Covers remain attached to the binocular barrel and hang down when in use. Model fits objective lens barrels with an outer diameter 51-52mm. Remember to measure the OUTSIDE DIAMETER (including armoring) of the barrels of your binoculars to get accurate sizing. Fits Opticron Models: Alpha ED 8x42, 10x42. Explorer WA 8x42, 10x42. Explorer WA Oasis-C 8x42, 10x42.

Review: Perfect Fit to Leica Ultravid 8x20 BR Binoculars - MUCH better than Originally-Supplied Caps - Yes, they seem somewhat overpriced for what they are: two little rubber rings with attached caps. But I must say: they are an absolutely perfect fit to the objective lenses of the Leica Ultravid 8x20 Binos - and are FAR better than the Leica originals (which required attachment to the neck strap if you wanted to keep from losing them, plus were "loose-fitting" to boot). These Opticron 30-31 mm caps not only fit just right, they won't get lost - and do not interfere in any way with the ability to keep them mounted when inserting the binoculars back into the case. (And yes, they do also perfectly fit the eyepieces - I may have to get yet another pair... ( sigh - :) ). Review: Purchased as lens covers for Leica Ultravid 8x20 binoculars and Leica Monovid 8x20 monoculars - I bought these as objective lens covers for my Leica Ultravid 8x20 compact binoculars. They are a good fit and work on the eyepiece side as well. The Leica's come with eyepiece covers, but they must be used either loose or attached to the strap. I prefer to keep these as pocketable as possible, so I don't use the strap. So I'm getting an extra set to use on the eyepiece side as well. Note, however, that using them on the eyepiece side means that either they sit a bit awkwardly on the pull-out eyecups OR they have to sit on the barrels where they will ever so slightly hit the Ultravid's wonderful and delightfully oversized focus knob and prevent the binoculars from fully folding up (it's about a 2mm difference in total). No impact on folding up if used only on objective end. Since the Leica Monovid 8x20 is basically a single tube Ultravid, I tried the lens cover on the Monovid object as well and it's a great fit. Moreover, it's slim enough that the Monovid will still fit in it's leather carrying case with the objective cover left on! My previous solution, a hard plastic flip cover suggested on some sport optics forums, is more durable but precludes the use of the Leica carrying case when mounted. It's also much stiffer and harder to open (it's really designed as a cover for a rifle scope). This Opticron cover is a much better solution for a birder like me. The material grips well to both the rubber armored Ultravid (I have the BR model) as well as the metal barrel of the Monovid. Pricewise, these are a bit expensive, but there's almost nothing else out there at such a compact size. So I'm buying two more pairs: one to use on the Ultravid eyepieces and another to put on the Monovid. ## Features - Fits tube with outer diameter 51-52mm - Friction fit over objective lens tubes - Easily removable - Protects lenses from dust/dirt - Hang down when binocular is in use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00I3ZZZVI | | Age Range Description | Adult | | Best Sellers Rank | #97,268 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #59 in Sporting Optics Covers | | Brand | Opticron | | Built-In Media | Lens covers | | Coating | UV-Protective | | Color | Black | | Compatible Devices | Binoculars with tube diameter 50-52mm | | Customer Reviews | 4.5 4.5 out of 5 stars (1,270) | | Diopter Adjustment Range | +/-5 diopters | | Enclosure Material | Rubber | | Exit-Pupil Diameter | 6.38 Millimeters | | Features | Lightweight | | Field of View | 7 Degrees | | Focus Type | Fixed Focus | | Global Trade Identification Number | 05036422310460 | | Item Weight | 1.28 ounces | | Manufacturer | Opticron | | Manufacturer Part Number | 31046 | | Model Name | 31046 | | Model Number | 31046 | | Mount Type | Tripod Mount | | Objective Lens Diameter | 51 Millimeters | | Size Map | Compact | | Specific Uses | Hiking & Outdoors | | Warranty Description | 2 year | | Water Resistance Level | Water Resistant | ## Product Details - **Age Range (Description):** Adult - **Brand:** Opticron - **Objective Lens Diameter:** 51 Millimeters - **Special Feature:** Lightweight - **Specific Uses For Product:** Hiking & Outdoors ## Images ![Opticron Rubber Objective Lens Covers 42mm OG M Pair fits models with Outer Diameter 51~52mm - Image 1](https://m.media-amazon.com/images/I/61YzrUDzngL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Fit to Leica Ultravid 8x20 BR Binoculars - MUCH better than Originally-Supplied Caps *by S***S on June 3, 2025* Yes, they seem somewhat overpriced for what they are: two little rubber rings with attached caps.

These 42-44mm covers are a perfect fit. Snug but easy to slip on. Good quality material. These binoculars came with caps that have no attachment, so this was a "must" (wish I had done this long ago). I was taken back by the price, but once I received these covers, it appears they might be worth it. Attached pic shows one side with cap on and the other side with cap removed so you can see the natural fall point. Nikon Laserforce 10x42 range-finding binoculars: measured objective was about 54.6. The 53-55mm covers were a perfect fit. I was a little worried that they'd be too snug, but not the case. They fit just as nice as the aforementioned covers described above. The covers that come with these Nikon binocs are 'plug-inside the objective tube' rather than a cover. After several uses, I found that much as I like the plug design for sealing out the elements, they just never went in easy. It always took a little fiddling and some moderate pressure to get them in (one slip and you could easily end up with your greasy fingerprint smushed onto the lens). These new covers go on very easy without any fiddling or unnecessary force, and they are plenty snug that they won't come off. If I had not purchased these covers for my Leupold binocs, I would never have purchased for covers my nice, new, and expensive Nikon binocs. But I'm glad that I did. Much as I like these Nikon range-finding binoculars (they are awesome), I was getting tired of spending 30 seconds and, arguably more importantly, having to divert all of my attention to the binoculars just to secure the objective lenses. ## Frequently Bought Together - Opticron Rubber Objective Lens Covers 42mm OG M Pair fits models with Outer Diameter 51~52mm - 42mm Binocular/Monocular Objective Lens Caps Internal Diameter 51.8-53.3mm Rubber Cover Set Black, (51.8-53.3LC) - Opticron 31020 43mm BGA Binocular Rainguard Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/12564786-opticron-rubber-objective-lens-covers-42mm-og-m-pair-fits](https://www.desertcart.vu/products/12564786-opticron-rubber-objective-lens-covers-42mm-og-m-pair-fits) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-01*
