Tested using a Nikon D3300 with the 18-55mm lens and a lens hood (HB-47). I had no problems using this with the camera, both with and without a tripod. Since I had a shorter lens, I bundled the lens portion of the cover together and secured it with tape (the middle part) and the end part with the velcro strap stayed in place. I simulated rain by using my shower, aiming the water at the back of the cover (the viewfinder side), with a box inside instead of my camera. The box remained dry, and I was able to put my hands inside without getting too much water. However, I'd be cautious if using it in strong winds. This is a good alternative to the clear plastic bag method I was using.

The one downside to a more universal fit camera rain cover, as opposed to a version that comes in a few sizes, is that it might end up being a nightmare to fit and set up. And this is kind of the problem I have with this rain cover. While it does fit every size of mirrorless cameras I threw at it (all bigger than APS-C), there is just so much room left in it. You can honestly probably fit a smaller cine camera in there, though it's not really compatible with all the extra attachments so it still won't make great sense. The clear window on the back is so large it can wrap even the bottom of my camera, though sometimes I wonder if that isn't so that you can see your tripod settings (if you leave the bottom zip open to use with tripods). Still, this oversizedness does make it a bit of a hassle to manage all the extra material. The lens portion isn't much of an issue since there is a integrated elastic to cinch up around the lens. The arms portion aren't too bad because at least it lets you put your arms through even wearing a reasonably bulky jacket. It's mostly the bottom/height of the whole rain cover that makes it awkward.

That said, I do appreciate the little viewfinder hole so that it plays well with the EVF's proximity sensor. I did find that on my larger cameras the hole is a bit too small to fit the EVF, though if I wanted to specifically personalize it for that camera I would easily cut the hole larger. Even if I keep the EVF inside the cover but facing the hole, I am usually still able to see through it perfectly and most of the time the proximity sensor still play along too. I do appreciate the little adjustable shelf over the EVF, which protects it but also keeps your glasses out of the rain too.

Overall, for an inexpensive one-size-fits-literally-all (other than your most ginormous lenses) rain cover this does a great job. It just becomes a matter of if the oversized nature of this design becomes way too much of a hassle in handling... though at least it does mean that once the internal lens collar strap is undone, you can remove most cameras from out from the arm holes instead of needing to open up the zip underneath.

This camera cover from K&F is well made, light and packs away easily for travel and transport.

It can be used in a hide environment or simply outside to give protection against the elements. Particularly useful for anyone outside for an extended time such as wildlife photographers, sports photographers, even wedding photographers on a bad day.. Very flexible in that is can fit most shapes and sizes of cameras and has a transparent window to see the LCD screen.

For a small price it will protect expensive equipment and allow you to continue to operate in poor weather conditions. Although I think designed primarily for use on a tripod it could still be used handheld in an emergency.

Definitely recommended if you plan on extended periods outside where you need some protection for camera and lens.

I used this during a downpour and was honestly impressed. It fit my camera with the 24-200mm like a glove, and I had no trouble adjusting the lens with the Velcro and cuff design.
The clear window stayed fog-free the whole time. I still had full access to all the controls, even when mounted on a tripod. It’s bulky in the bag, but worth carrying when the weather turns.

This rather decent camera cover arrives inside a slim easy to recycle cardboard box. A cover, that like all of the K&F products that I have, has an excellent build quality. A cover that provides really good protection against rain, sand, snow and dust.

It's also really well designed with a clear back window to view the live view screen. Plus it's got sleeves with pull cords, which makes operating my camera nice and easy. The maker has even included zips underneath, so you can still mount the camera on a tripod and keep things nice and dry.

Personally not keen on the cut out hole that's designed for the rubber viewfinder to fit through. A fitting process that can be fiddly to use, plus there's a strong likelihood you'll lose your viewfinder, when the cover moves around. But that's a problem that exists with many other brands of camera protectors that have holes cut into them. It's easily fixed by taping over the hole with clear tape and using live view instead.

The other thing to know is while the orange velcro strap does keep the cover well attached to the lens, that can affect autofocus. In particular if the lens needs to move, so sometimes (usually depending on your subject material) you might need to modify this area slightly. Something you can do by pulling the lens part of the cover back to the body and lightly taping on a very loose light weight plastic bag that can move along with the lens.

An approach that's also useful if you want to use this with anything bigger than a 200mm lenses. That's because this cover isn't designed for for use anything like a 300-600mm.

The compact size also means you can't use monitors and other off camera kit inside this cover, not even small ones. But it's no big deal to run cables through the arm holes and cover that external equipment separately. You could even use the included drawstring bag for that.

Another thing to consider is the chance of condensation, a problem that exists with all camera covers. One solution to that is to slowly acclimatise your camera to the outside temperature. Something you can do by leaving your kit bag unzipped slightly or leaving your flight case propped open by a few mm. Another answer to this issue is to tape a couple of small slica bags inside the cover.

Overall ? Despite some limitations, many of which exist with other covers, it's a really nice, very effective cover, especially the great price.

I was needing a camera rain cover to keep my camera dry in scheduled rain setting session, it worked great!

The first time setting the cover up took a bit but once I did it a few more times it got easier. Once its on, it stays in place and keeps the entire camera dry. It fully covered my FX-30 rig (without a monitor) while still being able to view the built in screen with the clear window.

There are arm sleeves to be able to adjust settings, controls and press buttons without having to take the cover off and risk getting water on your camera.

This is a solid addition to my bag for any outdoor shoots weather you're planning to get soaked or unexpectedly!

Got this rain cover five days ago just in time for the mixed weather we've been having this June. Used it last week during a sudden downpour while photographing some street scenes in town - the cover kept my Canon and 70-200mm lens pretty dry. Its TPU material is genuinely transparent enough to see camera settings clearly, which was my main concern before ordering. The adjustable sleeves work well with both my Canon and Nikon setups, though it takes a moment to get the fit right initially. The anti-fogging mesh prevented condensation issues that I've experienced with cheaper covers. The velcro adjustments hold securely without slipping during use. However, the cover is somewhat bulky when folded, taking up considerable space in my camera bag. Also, accessing smaller camera controls through the material requires more finger pressure than ideal. The double waterproof zipper design works smoothly for quick camera access. For our unpredictable Canadian weather patterns, it's proving to be a worthwhile consideration that gives me confidence to shoot outdoors regardless of conditions.

I have started using K&F gear quite a lot for my camera as the quality is great and the prices are superb, what other companies charge for the same piece of kits can sometimes be so much, yet its all the same really.

This fits my cameras perfectly easy to install and quick too so if you're out on a shoot and suddenly the heavens open, its very easy to grab this and get your precious camera covered and water proof, very impressed with K&F gear so was happy to get this, and certainly recommend it.

Great value and good quality gear so far.

The K&F Concept Professional Waterproof Camera Rain Cover comes inside its own draw string carry bag. I have tried it over my professional sized mirrorless Canon Eos r5 with a variety of lenses. Getting it onto your camera is easy, even if your camera is already on a tripod when rain strikes. There is a large zipper along the base of the cover that you open via dual zips; and slide down over your camera. The two zips move smoothly and make it easy to close around the base of the camera whilst it’s on a tripod, sealing from both sides. It has a large lens cover; with an elasticated strap to cinch it tight. It just holds my camera and a 70-200 f2.8. Its plenty wide enough for my 82mm lenses which are the widest I have.

On the back there is a large transparent window, it doesn’t let you use the touchscreen but there are two hand holes you can use to get access to it. On the top of the window there is a Velcro flap; under which there is a cutout for a flashgun or microphone attached to your hot shoe to go through. Using this will reduce its water proofing.

After use it folds up nearly flat and easily fits back into the pouch. It’s nice and flat which makes it to pack into your camera bag for those days of rain. Great for outdoors UK photography or holidays in the tropics.

Another brilliant product from K&F thats well thought out, with lots of useful features. Its a handy little raincoat for your DSLR, to protect it from rain, or in my case dust.

What I liked:

There is a clear cover at the back, so you can still see your cameras screen and there is a little hole for the viewfinder, which has a cover over it that velcros into place.
The sides have openings to allow you to put your hands into the cover to use the camera, which can then be closed shut again using the pull cords and toggles.
The front of the cover has a rubbery seal that clings to your cameras lens.
The zipper underneath can be zipped from both ends to enclose around the tripod and these zippers are also water resistant.

The whole thing looks and feels like a quality item and is all sewn together well, with no loose stitching. I have been planning to video record some woodworking projects to post online and was wondering how I could protect the camera from dust and I think this product will be perfect. I am very pleased with it. I'd say its very good value at the current price of £17.99.
