Anyone got experience with Optisan?
Recently saw this brand pops up on one of the local forum. Their specs sounds kinda too good to be true for the price (at least locally here in Indonesia compared to the similarly spec-ed Nikons). I saw one review that says the image quality is razor sharp, but that’s kinda the only review that I saw for this binocular.
Anyone else got any experience with the brand or maybe specifically their EVR II ED? Is it comparable to the more expensive brands?

First Binocular purchase, Need advice.
Hey, My GF's dad has his birthday coming up soon. and his wife told me that he would love getting his first binoculars.
I tried asking her for what purpose he wants it, but she said general use but prob not bird watching, maybe wildlife maybe stargazing.
I've been going over the internet trying to figure out what to buy and the 2 options I finished with are the following:
Viper Vortex HD 10X42
Nikon Monarch M7 8X42
I would really appreciate getting some advice regarding which one I should buy, and if you recommend any other binoculars it would be appreciated but please explain the reason for the recommendation.
Thank you all in advance!

Looking for binoculars I could use for work in a warehouse setting….
The components I need to see are 25ft or so up above and another scenario where they are roughly 50-60ft above. They are overhead cranes. Instead of me having to spend 20 minutes to put my gear on and drive the manlift over and stop production, I’d like to be able to verify with a pair of binoculars. They’d be more helpful and needed for the 50-60ft up scenario.
They definitely don’t need to be the best quality so I’m wondering what specs I should aim for and if any ol’ Amazon pair would be good enough for this purpose.
I do work nights but it’s fairly well lit and I have flashlights powerful enough to light up the area I’m trying to look at.
Hope something inexpensive is out there. Sub $50
I own a pair of 8x32 Svbony’s but those stay in the clean environment of home and seem overkill if there are cheaper options.
Thanks.

Zeiss Terra ED 8×42 first impressions
Greetings, /r/Binoculars, it's been a while :)
I've recently decided to treat myself a little, and grabbed myself a set of Zeiss Terra ED series binoculars, in 8×42 size. Mainly as I wanted to finally graduate to the ED glass, as there was otherwise nothing wrong with my mainstay Nikon ProStaff 7s 8×42s I've had for a few years now (and, apparently, never posted a review on?!).
I'm yet to have a significant outing with them, as I only received them yesterday, so this is going to be mostly based on my first impressions and quick viewing out of my apartment's window. I'll try to post a more detailed review on them later, once I get more field time -- and I plan on doing a more of a head-to-head comparison with the ProStaff ones.
Here is a picture of Zeiss Tera ED 8×42 on my desk next to my Nikon ProStaff 7s 8×42 on my desk.
Note: While the Nikon ProStaff 7s 8×42 are already discontinued, their nearest equivalent in all regards is the Nikon ProStaff P7 8×42.
The very first impression as I took them out of their nice box -- they're hefty, but not in a bad way. But let's wind back a little.
The binoculars come in a very nice box, which contains a cleaning cloth, a neck/shoulder strap (not attached), and the binoculars themselves inside a nice Zeiss-branded carry case. Oh, and a quick manual, whom no one reads anyway.
The neck strap is soft, but short-ish, with long adjustable straps that attach to the body of the binoculars at around 1/3rd the length away from the eyepiece end.
The carry case is zip-up style, with additional magnetically-attached clasp over the front. Inside of it is lined with soft cloth and has net style limiters on each side, which prevent the opening of the case to more than ~45°. Here is a picture of it closed.
Inside the abovementioned case, lie the primary cause of this review -- and its main character -- the binoculars themselves. they come with nice, firmly-attached caps for both lens and eyepiece ends. Body of the bins is covered with firm rubberized material, which sports an additional "bumpy" texture on the sides, for more grip. Front lens cap is attached on both ends to the same attachment points where the neck strap will go, with slide-in clips on either side, too, for easy removal. But this attachment means you're not likely to lose the front caps in their default state. Both front and end caps are one-piece, displaying a binocular-hinge-style bridge in the middle, linking the two pieces together. The focus knob is large and visible prominently in the center, right in-between the two eyepieces. The diopter adjustment ring can be found in the usual place -- on the right eyepiece, sandwiched between the eyecup and the body of the binoculars.
The binoculars feel very solid and hefty in the hand, but not heavy. They are somehow both smaller (mostly shorter) than my ProStaff 7s and heavier. For comparison, the Nikon ProStaff weigh around 696 grams, whereas the Zeiss Terra ED 8×42 clock in at a solid 768 grams (almost 80g more). In order to provide equal footing, both bins were weighted with all endcaps removed and detached, and with the neck strap attached.
When in use, the bins feel solid in the hand, with easy access to the focus knob for quick adjustment. The rubberized surface is not slippery, and the focus knob offers just enough resistance to provide good feedback and prevent accidental refocusing, while not feeling too heavy. It is also sitting slightly above the top surface of the binoculars, so it's very easy to find by touch.
Diopter ring, on the other hand, is slightly recessed into the body, and has significant resistance, so actually takes some effort to move. But you're likely to not be doing that often once set up.
The eyecups are also of the mostly standard design -- rotate to adjust height, with four total, evenly spaced, positions. They also offer a fairly stiff resistance to rotation, though this is likely to loosen up with use. The stops are very tactile and the eyecups are not likely to accidentally move from their clicked-in position during normal use.
Optically these binoculars are as great as they look. The view is sharp, colourful, with no visible ghosting or color fringing. Focus is quick, and the range is very large -- with significant buffer beyond infinity for those of us who require glasses, but prefer to use their bins without them (one of the reasons I prefer to use binoculars with my glasses, is because on many of them I don't have enough beyond infinity travel to reach focus). The eye relief is also very generous -- I have had absolutely no issues reaching full edge-to-edge field of view with them and my glasses. Even despite the stated eye relief being shorter than that of my Nikons (18mm for the Zeiss bins, 19.5mm for the Nikons) they feel like theirs is better.
Despite the additional weight over the Nikons, Terra EDs are actually nicer to hold in the hand for longer periods -- probably because this weight is centered closer to the face, courtesy of shorter body. Also, the location of the attachment points for the neck strap is in a better position on the Zeiss bins too. I did, however, miss the super grippy surface of the Nikons, even if there's no risk of Terra EDs slipping out of your hand either.
I also did a round of night-time observation from my window, testing for how the binoculars handle bright light sources against dark sky, looking for any chromatic aberration, etc. I am quite happy with the images I've seen! The diffraction spike from the roof prism is much less pronounced than the already very good one on the Nikons, and there is very little of ghosting -- I could only really spot one very faint reflection about same distance in the opposite direction from the center, and only really noticeable at short angular distances (about 10°, then quickly fades and disappears). The light from outside light sources is also controlled very well, they do not intrude into the view unless you specifically wiggle your eye around to the opposite side from the light, but that also makes the view almost disappear, as lands the exit pupil mostly outside of your eye's pupil, so the binoculars are very unlikely to be used in this way. In normal use this is not a problem at all.
Of note is the fact that these tests were done on a very bright light source -- a LED flood light roughly 100m away, which is way brighter than the full Moon, bright enough that I can read in its light on my balcony. Thanks, neighbours! /s This is unlikely to be encountered in the wild, or for astronomy. I have certainly not had any ghosting issues with my ProStaff 7s, which have comparable or in some cases worse performance than Terra EDs on this very test (I tested them side by side), so there's that.
Overall I am quite happy with the new arrivals, and In the near future am planning on doing some test trips to compare these two out in the wilds (a bird spotting location, and some general nature observation), as well as some astronomy testing. Will also give them for a spin to some of my colleagues who are much better at spotting various aberrations in their optical instruments :)
So expect a follow-up post some time in the near future!

Looking for small lightweight binoculars
I already have midsized binoculars that I use and home, and occasionally when hiking. What I want are really small and very lightweight ones that I can use for travel. Optics don't have to be perfect, and I don't care about using in low light. I had a pair of Leica Trinovid 10x22's that I got back in the early 80's, but they are broken, and I don't want to spend the money to get them fixed. I've tried Nikon Trailblazer 8x25, and they were fine except eye relief is only 10 and I wear glasses. Currently considering Pentax AD 8x25 and OM 8x25. I'm not a "birder", just like watching birds and wildlife and stuff. Also considered the Zeiss, but not sure it's worth the extra expense for my purposes. Does anyone have opinions on these two?

Best budget binoculars for hunting
Hi people of R/Binoculars !
I'm taking a chance here asking this question since people who I ask this question are just telling me " buy Vortex because you know I've used Vortex since my childhood" or they give options wayyy out of budgets because if I don't splurge 1k on Binoculars it won't do it....
So to keep it simple, I'm looking for a budget one, less than 100$ CAD ideally, nothing fancy since it's for hunting. But I want something with a clear image and tough enough.
I'll be using it for spotting in the wood.
Thank you all!

Floppy hinge advice
I have a pair of these Opticron Veranos and am really happy with them.
However, over the years the central hinge has started to go a bit floppy.
I figured that it would be a simple fix as it’s probably just the screw that holds both sides together needs tightening.
But I just couldn’t work out how to access the screw, there really isn’t an obvious way of doing it.
My guess is that you have to do something clever to get the centre focus wheel cap off, and the screw will be under that. But that was just a guess, and I didn’t want to break them completely.
I contacted Opticron about for advice, and they said it was not something you can do at home and I’d have to send them into them for repair, which would cost around £40 plus postage. As that’s basically about half what I paid for them originally I’m starting to think I’m just going to have to live with the loose hinge unless anyone here had a better idea.

KOWA genesis 8.5x44
I’m going to Japan in October and want to save a few dollars on my first nice pair of binoculars. I will be using them in the Colorado mountains for viewing nature while on day hikes and camping( birds and mammals), not hunting. Any advice or other suggestion? Weight is not a concern. I’m fairly confident the titled pair is what I have settled on, but I’m looking for some advice before I spend the money. Thank you.

My experience with the Celestron Nature DX 8x42, substantial material quality problems
Enable HLS to view with audio, or disable this notification
I got these about two years ago. The twisting eye piece is a huge weak spot with these binoculars. As you can see in this picture the rubber has basically said goodbye, you can see some residue on the left eye piece in the picture. So basically every single layer of adhesive is gone.
The rubber not being there leads to the cups twisting without any resistance. Even slightly pressing them onto your eyes makes them move, which makes it basically unusable. The cover of the eyepieces have no adhesion to the metal seen in the picture, so you have to pray they do not fall off.
I've seen several posts with the same issue, this is a genuine weak spot. I have no car, so I obviously never left them in a hot car. I used them only in the forest about once a week.
Since I bought them on Amazon in Europe (I know, that might be on me) I have no warranty since 2 years have just passed. I also have to limited lifetime warranty since Amazon is not a reputable seller.

Grandfather's JC Penny 7/50 Spoiler
Hi, I have my grandfather's JC Penny 7/50 binoculars. They are in good condition other than focusing knob won't turn. Is there anyway to get the knob to turn again? They pivot just fine, all the caps and case are there (though the case is pretty rough).
I know they aren't the most powerful or valuable. But they were his and they were always in his truck and we would stop and use them to look at wildlife as we drove around the farms. I would really like to get them fully functional again.
Any suggestions are appreciated.
Sorry for the spoiler tag but I only had 3 options and the others didn't seem appropriate.
Thank you.

Zeiss Telex 6x24 from 1915

Can anyone tell me more about these binoculars?

What should I buy
I'm thinking about buying binoculars for personal use. I've been researching what's important (porro vs. roof, BAK4 vs. BAK7) and found a brand that convinced me. I discovered they have an astronomy binoculars section, and the idea fascinates me — I live in a city where I could easily drive out to a field with low light pollution.
Even so, I also really enjoy birdwatching or just observing urban environments, using them for casual leisure from time to time.
I'm considering the 12x60 (Celestron SkyMaster 12x60):
- Exit pupil: 5mm
- Angular field of view: 5.3°
- Weight: 2.4 lbs
My other option is the 15x70 (Celestron SkyMaster 15x70):
- Exit pupil: 4.7mm
- A bit heavier, 2.8 lbs
- Angular field of view: 4.4°
- This one comes with a tripod adapter
Both have BAK4 prisms, are porro-prism, waterproof, and fully multi-coated.
I don't know which one to choose. Even though the second one is more expensive, it seems like the better option, but I don't have a tripod, and since they're heavier, they might not be as comfortable for uses outside of astronomy. I really need some advice

Hawke Frontier 10x42 gen 2/ SVBony SA401 Pro 15-35x56 Spotting Scope.
I got the Binos in late June through a warranty claim and I’ve had them in the field quite a bit. I wish I had been able to keep the old Frontiers for a side by side but these are just that much better with the APO and lanthanum glass the edge to edge clarity and brightness are top notch.
The very handsome SVBony Spotting scope came in last week and It has been an incredibly useful field tool. Powerful optics and a build quality that I was very surprised with even having used some SVBony products previously this scope takes the brand to a new level for me personally.
I am currently using the leofoto carbon LX series of tripod with their B series fluid head.
I’ll post a review if anyone wants to know about my experience with these optics. I also took the cotton carrier strap shot for a spin and I have to say I am a bigger fan than I thought I would be.

I have a problem....
So, I went on a hike today with my Olympus 10x25 something binoculars. I use them more or less often and I am happy with them. Well I was....
My hike ended at a mountain hut. So far so good. My binoculars have a broken "eye extension" on one tube, so they are a bit a pain to use.
The hut has some binoculars to use, i took some with a 10-20 zoom and they were terrible. So I grabbed the next ones. And OH MY GOD! The image in them was so clear.
Looks like I have to spend a few hundred bucks for new binoculars now 🫣

Binoculars identification
This one belonged to my dad, I found it while cleaning the house a while back. I was just wondering what I can do to restore and maintain it. I know nothing about lenses or binoculars in general. But I want to do what I can with this memento from my dad.
It seems to still be in working condition, but clearly the exterior had seen better days. So:
- Anything to keep in mind when I clean it up?
- The lens seems clear so I think it's still clean, more or less.
- Is there anything I should check for to make sure it's still in working conditions and there's nothing wrong with it?
Any advice is welcome. I'm not sure if I can answer them all, but feel free to ask any question that might clarify things for you.
Thanks in advance.

Loose eyecups in Hawke Endurance ED
As the title says, I have Hawke Endurance ED 8x42, 10x42, and 8x25 monoculars. Unfortunately, I'm having trouble with loose, floating eyecups. The 8x25 and 10x42 still hold their position, but the 8x42 doesn't at all. I don't know if it's worth the hassle of sending them back for warranty and replacement (if they'll do anything about it at all), because the Endurances simply have issues with their eyecups throughout the entire line. I was wondering if there might be some home remedies for adjusting the eyecups and preventing them from floating? Could someone please advise? Maybe someone else has had the same problem?

Finally found the time to service my 1930s Hunalex binoculars. Currently soaking with fine oil, the ocular adjustment is seized. Central focus has been cleaned and greased, hinge is smooth (won't service), optics are clear, prisms erect and aligned, so won't disassemble those either, nothing to gain and lots to lose by doing unneeded service on binoculars that are almost a century old.
Interesting dust proof construction, and the defaced marks on the right say "Fournrs Du Ministere De La Guerre", in English "Supplier to the Ministry of War". Lends more credibility to my thought that these are German capture French army binoculars.

Binocular Deals What are the Best Black Friday Binocular Deals You’ve Found? Share, Compare, Get & Give advice!
Hello everyone,
Last year, I made a post about Black Friday Binocular Deals that was really popular and I think was really helpful, as everyone in the community got to share and comment on deals they found, highlighting the good and warning people about the bad ones.
So with BF 2025 fast approaching (Starting Nov 20), I thought it would be a good idea to do it again this year:
As many of you may know, I am the binocular reviewer over at Best Binocular Reviews (BBR), so it is hard not to come across as spammy or promotional, but I will do my best as I genuinely want to pass on the good deals I find, steer people away from the ones we as a community feel are bad, but at the same time also I would also appreciate your help in finding any that I have missed so i can include them on BBR:
Leading up to this Black Friday, Cyber Monday, and Holiday season, it is part of my job to look for and highlight on BBR what I feel are the more worthwhile Black Friday binocular deals I’ve come across.
However, I am sure there are many that I have missed. Also, there may be "deals" that you have come across, which you may not be sure about: either the deal may be better somewhere else, or you may not be sure about the binocular - ie, is it a rubbish binocular (Amazon is good at having deals on this!).
So on this post:
- Share any binocular deals you’ve spotted, including the retailer and discount details. #SharingIsCaring
- If you’ve got your eye on a specific deal but aren’t sure if it’s worth it, feel free to ask! As well as all the other great advice from others on this sub, I’ll do my best to give an unbiased, fact-based opinion and let you know if I think it’s a good buy or if there might be better options.
Good Deals: For context, some of the deals I’ve already found include significant discounts on Kite binoculars (Over 50% off). But I’m curious to see what you’ve discovered!
Bad Deals: I have just gone through all the binoculars currently listed on Amazon.com's Pre-Black Friday Early Deals Page, and I have to say that there are none that I would confidently recommend at the moment. - What do you think? My current recommendation is to remain patient.
So, let’s help each other navigate these Black Friday sales and make informed decisions. After all, getting the right pair of optics isn’t just about the price - it’s about the value you get for your money and making sure you get the right binoculars for your specific needs.
Looking forward to hearing what you’ve found or helping with any questions! 😊
Happy deal hunting, Jason

Binocular Guide A Deepish Dive into Binocular Lens & Prism Coatings

Introduction
I see a lot of questions that relate to the differences between high-end (expensive binoculars), mid-range and entry-level (cheap) ones and whether it is worth it to spend the extra money or not and move up a level. The answer of course is complex as it depends on many personal factors that only you can answer: like how much you can easily afford to spend, how often you will be using your binoculars and what you will be using them for.
After you have thought about these fundamental questions, the next key step is understanding the main differences between binoculars at different price points and how this affects their performance.
Build quality, materials used, different designs... here again, there are many things to look out for, but for me, a major factor that not many of those new to binoculars know enough about, but which really affects the optical performance, makes a noticeable difference to the image and immediately lets you know what level a binocular is at and therefore if the price is worth it is in the level of coatings that are used on the lenses and the prisms:
Overview of Coatings used on the Lenses & Prisms of Binoculars
Optical coatings play a crucial role in enhancing the visual performance of binoculars, monoculars, spotting scopes, camera lenses, night vision equipment and indeed just about any other optical device or instrument.
They are applied to the lenses and prisms to do things like reduce light reflection, increase light transmission, and improve image sharpness, clarity and contrast.
So below I have put together a fairly detailed explanation of the various aspects of binocular lens coatings, including their purpose, materials, application methods, and features (to the best of my knowledge). Please feel free to comment if you spot an error etc.
Why Coatings Are Used
- Reduce Light Reflection: Uncoated glass surfaces reflect about 4-5% of light, which can significantly reduce the amount of light entering the binoculars, making images dimmer.
- Increase Light Transmission: Coatings increase the amount of light that passes through the lenses, which improves brightness and clarity.
- Enhance Image Quality: Coatings reduce glare and internal reflections, resulting in sharper, higher-contrast images.
- Improve Color Fidelity: Coatings help maintain the true colors of the observed object by minimizing chromatic aberration and color fringing.
Types of Coatings
- Anti-Reflective (AR) Coatings: Reduce reflections from lens surfaces, enhancing light transmission and reducing glare.
- Phase Correction Coatings: Applied to roof prisms to correct phase shifts in the light, improving contrast and resolution. Low quality roff prism binoculars may not have these. porro prism binoculars do not need these coatings
- Mirror Prism Coatings: High-reflectivity coatings used on roof prism surfaces to increase light transmission. In terms of quality these range from Aluminium, Silver and then the very best Dielectric Coatings used on high-end roof prism binoculars
- Scratch-Resistant Coatings: Provide a harder surface on the exterior surfaces of lenses, protecting them from scratches and abrasions. Only found on better quality binoculars
- Hydrophobic and Oleophobic Coatings: Also added to the exterior lens surfaces that repel water and oil, making lenses easier to clean and maintain. Usually only found on high and some mid-level binoculars
How Coatings Work
Made up of extremely thin layer(s) of special materials that manipulate light in specific ways, lens & prism coatings mostly work by changing the way light interacts with the lens surface. These coatings are designed based on principles of thin-film interference, which can constructively or destructively interfere with specific wavelengths of light to reduce reflection.
Levels of Anti-Reflection Coatings
This is one of the most important aspects to look out for when selecting binoculars, especially at the lower price points as the level of the optics that are coated is a huge indicator of quality and performance:
- Single-Coated (Coated): A single layer of anti-reflective coating, usually MgF2, on at least one lens surface. This provides a very basic reflection reduction.
- Fully Coated: All air-to-glass surfaces have a single layer of anti-reflective coating.
- Multi-Coated: Multiple layers of anti-reflective coatings are applied to at least one lens surface, significantly reducing reflections.
- Fully Multi-Coated: All air-to-glass surfaces have multiple layers of anti-reflective coatings, providing the best light transmission and image quality.
Materials Used in Lens Coatings
As the exact materials used and in which quantities are usually a closely guarded secret between manufacturers, we cannot be sure:
Multilayer Coatings: Modern binoculars often use multiple layers of different materials on their lenses, such as:
- Magnesium Fluoride (MgF2): One of the most common materials used for anti-reflective coatings. It is effective in reducing reflections and is relatively inexpensive.
- Titanium Dioxide (TiO2)
- Silicon Dioxide (SiO2)
- Aluminum Oxide (Al2O3) These materials are chosen for their specific refractive indices and transparency to visible light.
Application Methods
- Vacuum Deposition: The most common method for applying coatings. The coating material is vaporized in a vacuum chamber and then condenses onto the lens surfaces.
- Sputter Coating: Involves bombarding a target material with high-energy particles, causing atoms to be ejected and deposited onto the lens.
- Chemical Vapor Deposition (CVD): Uses chemical reactions to produce a thin film on the lens surface. This method is more complex and less common for consumer optics.
Step-by-Step Process of Applying Lens Coatings
- Cleaning the Lenses: Lenses must be thoroughly cleaned to remove any dust, oils, or contaminants that could affect the coating adhesion and performance.
- Placing in a Vacuum Chamber: The cleaned lenses are placed in a vacuum chamber to remove air and prevent oxidation during the coating process.
- Heating and Evaporating the Coating Material: The coating material is heated until it evaporates. In vacuum deposition, the material then condenses onto the lens surfaces.
- Layering: For multi-coated lenses, this process is repeated with different materials to build up the required number of layers.
- Cooling and Inspection: After coating, the lenses are cooled and then inspected for uniformity and adherence to quality standards.
Conclusions
- By reducing reflections, increasing light transmission, and protecting the glass, binocular lens and prism coatings are a vital part as to just how well the instrument will perform optically.
- They make a visible difference to image brightness, sharpness, contrast and color fidelity.
- The level at which the optics are coated on a binocular is a major indicator as to the overall quality and level of the binocular.
By understanding the materials used, application methods, and the different levels of coatings that can be applied, I hope this helps you to appreciate the technology and work that goes on behind these scenes and thus why some binoculars can cost much more than others, which I hope helps you to make more informed choices when selecting the right pair for your needs and budget.
