I'm a sports photographer, and if it's raining, the games still go on. I keep a pack of these in my bag at all times. They are quick to put on when the rain starts, and I like that they have the hole in the back for the eye cup. That's a key feature for me!

The drawstring works OK, but I usually hit it with some gaff tape to secure the sleeve onto the lens hood.

I shoot with these sleeves on Canon 1DX MkII and Canon 7D MkII with grip, mated with Canon 70-200 f/2.8 and Sigma 120-300 f/2.8 lenses. It handles these large bodies and telephoto lenses, no problem.

I've only had to use this once since I purchased. A little difficult fitting over the viewfinder and to coordinate using your hands under the shield, but I know that will be easier with time. It worked very well during a little more than moderate rain storm. Worked as advertised.

I wanted something simple and inexpensive that would protect my DSLR from potential water spray while on a boat trip. This thing delivered. I wish the manufacturer would do a better job describing dimensions. I bought both the Original and the Small. I had no problem using the 'Small' on my Sony A77 with both my 18-270mm f/3.5-6.3 telephoto lens and my 16-50mm f/2.8 prime lens. This protector has plenty of room for a full DSLR body, even if you have a battery grip attached. Then, there is 12" of distance between the back of the protector and the hole at the end where the lends peeks out. So, assemble your camera, extend your lens to the fullest. Measure the longest distance (from the backside of the body to front of the lens). If it's within 12" you're good to go. If it's longer (and this means you're doing some serious telephoto work) you'll want something bigger. For most folks with consumer/prosumer equipment this is the one for you. I did find that trying to view my shot with this thing on was a bit of a pain. The plastic is mostly transparent, but not crystal clear (especially after its been crumpled after several uses). And making any setting adjustments, including zooming the lens, could be equally challenging. But assuming you can set and forget things for awhile, you should have no trouble protecting your camera without investing a small fortune for a custom shell.

The rain covers work very well on most of my cameras & lenses. It's easy to operate the camera with the rain sleeves on. The covers make it easy to see everything on the camera without removing them. The only problem I had was that one of the rain sleeves had a cut and a hole in it when I opened the package but other than that I like these rain sleeves. Now I can take pictures in the rain or fog.

A very simple and cheap solution that does just what it's intended to do. For a professional looking to go out shooting in rainy conditions all day, every day, a dedicated heavy-duty rain protection system would be recommended, but for 'emergency' rain use, these are great to have. I have been using the Original 18" sleeves on two different cameras when I go wildlife and bird photographing in the Florida wetlands, where rain is an unfortunate possibility almost any day of the year. Often I go for long walks far from shelter or cars and prefer not to haul additional lenses or bags with me, so I'll just bring the camera and mounted lens...these rain sleeves when folded up can easily slip into a back pants pocket and not even be noticed - just a few mm thick and no larger than a wallet's length and width. If I see rain coming, I can get the camera into the sleeve in under 30 seconds, tighten up the front drawstring, and work on mounting the eyepiece over the hole. Sometimes I just skip that step as I can still shoot with the viewfinder even through the plastic - depends on how long I expect the rain to last. I use this sleeve on a medium-sized DSLR with a Tamron 150-600mm lens, and it fits very nicely, even allowing the Tamron full extension at 600mm. I also use this on a much smaller mirrorless camera body with a 70-300mm lens, and it's entirely too big but can still be used in a pinch. I do wish they made a size in between their 'small' 8" model and original 18" model - something like 12" would be perfect for a mirrorless or compact DSLR with a 70-200mm or 70-300mm mid-range zoom.
