OpticronRubber Objective Lens Covers 50mm OG S Pair fits models with Outer Diameter 56~58mm

I bought these for my Swarovski Curio 7x21 compact pocket binocular which I will return due to jittery image in hands see my review on Amazon on this binocular. These objective covers however are very nice and fit these binoculars very well. Not too tight but they work excellent and protect the objective lenses. Give these a try if you own a Curio 7x21 binocular.

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.

Fit fine, now if the rubber holds up I’ll be happy

I needed a pair of objective lens protectors to replace a pair I'd lost on an older model Selsi binocular. I used a micrometer to measure the outside diameter of the lens objective and it measured 63 mm. This said it fits binoculars from 60 to 62 mm and I could not find any for 63. Close enough. I was able to put the covers on and with a bit of effort "stretch" them over the 1 mm size difference. They seem fine. I'll wait a month or two and hopefully the rubber will become permanently stretched to keep the tight fit. I like the "ring" attachment so as to not lose my covers again. I gave it 4 stars instead of five only because it wasn't a perfect fit for a "standard" pair of 10 x 50 Selsi binoculars.

Leupold Yosemite 8x30 binoculars: measured objective OD was 43mm (old binoculars but I still use them a lot). 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.

possibly product is not bad ... but it wasn't sent to me, instead of that, I've received 1.5 times bigger caps

Perfect fit for my classic Japanese made Pentax 7x50 PCF stargazing binoculars. The original covers are always coming off in the case, dropping out of my pocket, and generally being a nuisance. No more. These flip down for use but stay attached, so they are always there and easy to replace when done looking through the binos. Love them.There are less expensive ones out there, but not in the size I needed.

See title why I bought them. Work perfectly and great material.

Son mi segunda compra en menos de un mes, los recomiendo ampliamente. Muy flexibles y la medida exacta. Gran rapudes de entrega...

For my nature binoculars. Old ones were worn out thyese were replacement. Work very well, fitted a treat. Fully recommend to protect your lenses.

replacement covers for opticron binoculars.....fir exactly

The fit is tight but they stretch. Easy to fit and replace the caps over the lens. Much better to have the lens attached. Very pleased with the product.
