OP/TECH USAFold-Over Neoprene Lens Pouch – Camera Lens Case for safe Lens Cover storage, Great for Photography & outdoor shoot, Keeps your Lens secure with No-Lose Lid-251 (Black) - Made in USA

This is a review fore the 253 Pouch with stated dimension of 2.5" dia. x 3" L. I really like these pouches for a couple of reasons. They work great because you don't have to deal with zippers and they don't take up a lot of room. You can a leave the Pouch on when you throw it on your camera bag because it doesn't add much added space over the dimensions of your lens. After you swap lens, they crush down and can be placed into your bag into pretty much any available space you have left.I use it on an SLR Magic 50mm/F1.1 FE Lens for Sony Cameras. The dimension of that lens are 2.6" diameter and 3.5" Length including the backing cap. Both of these dimensions are larger than stated by OP/TECH USA. But it still fits. This is because the material is stretchy and the collar on the pouch cap is fairly long. The 253 has collar about 1.25 inches. So even though the lens actually sticks out over the lip of the bottom portion of the pouch the long collar allows you plenty of length to overlap the top and bottom by at least a 1/4". I state at least, because I like to keep the original lens cap at the bottom of the pouch as a spare, so there would be another 1/8" if I just left that cap at home. Mind you, this lens is at the upper end of what this lens will fit. Also, the 50mm/F1.1 has a simple 1/2" screw on ring for a lens hood. The hood is included in my dimensions, so reversible petal style lens wouldn't have worked. Without the spare lens cap and the hood removed, the lens actually fits perfectly. So I really like that the flexible design allows me to accommodate the accessories if I want to bring them along. I did buy a more traditional zippered pouch for this lens, but it ended up being over bulky to the point where I couldn't put it back into my bag after the lens swap, so I would just leave it at home. I like bring the pouch in the bag because it provides some organization during the lens swap. I'm mentioned, I like to have an extra lens cap, so I know exactly where to find it if I need it. Also, I have a place to put lens backing cap along with a spare body cap after the lens swap, so it's there when I do my next swap. For this lens, you can also insert the lens with the back to the top allowing you to leave the pouch on the lens during the swap. This might be a small thing, but it frees up your hands for a quicker swap allowing you to put the pouch into your bag last. So I just shove the backing cap along with the body cap back into the pouch and crush it and cram it into any available space I can find. This is extremely helpful when I've just swapped from a long telephoto zoom lens that is now taking up twice as much space as the 50mm lens. Pictures included show lens with and without the spare cap and lens hood.If I could have one thing fixed on this pouch, I would ask OP/TECH a bit more silk screening. We've all seen athletic T-Shirts that have an oval of silk screening. That oval allows you write a name in the oval to allow the managers who do the laundry to sort out who they should return the shirt to after they've been laundered. Well, a similar silk screened oval would allow you to write the focal length to help identify it without pulling the lens out. This is particularly helpful if you are placing the lens with the front of the lens at the bottom of the pouch. If you have 2 lenses from the same manufacturer, you can have a couple of lenses have the exact same dimension because the lens bodies are shared and only the internal optics are different. I have Sigma 19mm and 30mm that like this. If I had Pouches for these lenses, I would have to pull out the lens to actually know if I had the lens the desired focal length.

Bought severa of these and always pleased with quality, ease of use and protection they offer.

304 fits my Tamron 11-20mm for Sony. 306 fits my Tamron 17-70 (Sony APS-C) and (my friends) Tamron 28-200 (FF). They have enough space in them for the UV filter, ND filter AND Caps attached to the lenses. These are my favorite lens pouches compared to others that are just so bulky and the strap get in the way. I will definitely be buying more!Update 01/24: I just purchased the 253 for my Sigma 56mm for Sony and it's a bit of a tight squeeze, but I'm sure it will stretch a little over time and I prefer them a little snug instead of loose on my lenses. I tested this one on my Sigma 30mm as well, but the 30mm is about 3/4 inch too tall and was very hard to squeeze it into the sleeve.

I wanted a neoprene or soft case with a lid for my lenses. In my past the lens came with a hard shell case when you bought them. Today camera lens come sometimes with a soft fabric cover case. It really does not provide the protection I want for my very expensive lens. I really like OP/TECH pouchs, I have bought two (2) of them and I would like it if they made all kind of shapes and sizes for various other lens. Very good quality and I live the fold over pouch lid. They fit snug around my lens and provide that protection I want.

I bought this to hold a unique item that I wanted to be able to transport, and it's worked perfectly for me. Can't comment on its intended use, but it functions as described. Closes tight enough to be secure, but opens reasonably easily when needed

Nikon, in their infinite wisdom, has decided NOT to supply lens cases for various high-priced lenses, including the Nikkor Z MC 105mm. Instead, you get an ultra-thin bag that offers no shock protection at all. No good.The OP/TECH neoprene lens pouch fits the subject lens perfectly, except you can't get it in the pouch with the hood mounted. That's OK, as it's the lens that really needs protection and I mostly use it for macro with a ring flash, so the hood isn't installed anyway.The Nikon lens is 3.4 inches (85mm) diameter x 5.6 inches (140mm) length and the OP/TECH pouch is advertised to hold lenses that are 3.1-3.5 inches diameter x 5.1-6.5 inches length.

Just the right thickness to protect without taking up too much space.

I use several sizes (253, 254, 304, 306) of the Op/Tech pouch to protect a collection of TeleVue astronomical eyepieces. These eyepieces are rather bulky & heavy (especially the Ethos series), & just tossing them in a bag is not a good idea.I needed pouches that would not be too bulky, hard to open in the dark, or likely to fall apart. The Op/Techs absolutely met all of my requirements. They are well-made from a soft, flexible material -- the caps are attached (sewn) at the top of the body & down about 1.5 inches along the body; they are cross-stitched around the cap top circumference & the body lower circumference. I highly recommend them.

Semble être de bonne qualité et recouvre ma lentille très bien . Le Néoprène est assez épais pour assurer une certaine protection contre des coups légers en voyage dans un sac à main .Seul le Néoprène à un odeur qui prend du temps à se disperser .

I have a couple of these, I use one for my Nikon TC-14 Teleconverter and the other for a manual 50mm pancake lens. Fits perfectly for both and gives plenty of protection when thrown in the camera bag

Teleconverters are awkward for camera bags - they're way too small for a typical lens pouch, and small enough that they will rattle around in a backpack. They tend to ship with a drawstring pouch that's not very cushioned and wastes space. They're fairly robust items (usually with limited or no moving parts), but shaking lenses can still make lens caps fall off, exposing the optics - and they're especially prone to knocking against other lenses or teleconverters (especially when trying to carry two in a bag space designed for one larger lens. They can also get scratched by any loose cable which escapes and flaps around inside a camera bag. So I wanted a small protective pouch that neatly fitted the teleconverters and padded them/saved them from scratches, while still letting me fit them neatly into a large camera bag, packed in around other lenses or together in a smaller pocket. For some reason, almost nobody else seems to make such a product - most other "small lens pouches" are much too big.Fortunately, these seem decent - I'm sure they'll tear under enough force, but my protective needs are reasonably modest, and I don't intend to let them move far before coming up against another lens or pocket - they're for going in a bag, not to provide full protection on their own. They could be a little more rigid (perhaps at least at the ends) for more protection, but these items are reasonably robust anyway, especially with caps held in place by the pouch. They're probably soft enough to help, if you're careful, with bare teleconverters, but that's not a risk (or smudge) I want to take.The attached picture shows Nikon gear: a TC-14E II and a TC-14E III in 251 pouches, a TC-20E III in a 253, and an FTZ-II in a 301. All seem a decent fit - they'll come out easily but not without an active attempt, and the lids close enough to stay in place and cover any gap. (One of the 251s is closed, the others have their lids inverted.) I imagine the 3 series would be the right width for a Z teleconverter, and any of these would equally fit extension tubes. For what it's worth, a 50mm f/1.8 E series will fit in the 251, and the AF-D version will fit in a 253 but is a little short for it (the AF-S is bigger, and I don't have, say, a 303 to test). Bigger lenses generally fit better in a camera bag on their own, though - it's for teleconverters that these pouches are most useful to me.They do seem to take a while to turn up, though - they shipped from outside the UK for me.

The 253 is an absolutely perfect fit for many of Canon’s EF-M lenses. Build quality of the pouches is excellent. An ideal solution for those looking to protect their lenses in a camera bag. The only negative thing I can think of is that the pouches are a bit on the expensive side.
