K&F Concept 40.5mm Lens Cap Cover, 4-in-1 Center Pinch Lens Cover + Anti-Loss Keeper Leash + Microfiber Cleaning Cloth Kits Compatible with Nikon, Canon, Sony, Fujifilm Camera Lenses

Fits perfectly on my 49mm lens. The springs are a little tight but better than being loose. To thread the small lanyard through the lens cap I used a needle to pull it through. Worked like a charm. I also attached the orange part to the camera strap which keeps it out of the way of the lens.

I've purchased 3 of these lens caps, so far (49 mm, 52 mm, and 55 mm). They're useful on vintage lenses, for which the caps are often less than ideal (or missing entirely).I really couldn't be happier with them. My only regret is that I didn't get them sooner.First, the build quality is great, they feel very robust; second, they fit like a charm, very snug, and I have no worry about them coming off unintentionally; third, their tastefully low-key branding doesn't spoil the look of the lenses; and lastly, they come with a sealed cleaning cloth, which is useful and appreciated.The cinch on the keeper comes loose far too easily, and I actually lost the 55 mm cap thinking that it was securely attached to my lens. I've never lost a cap due to removing it and sticking it in a pocket, so I'll have to buy another 55 mm lens cap and NOT use the keeper leash. Too bad, it seemed like it would be convenient. (EDIT: for less than $5 you can get several cord locking beads, using one of those on the leash keeps it tight on the lens and solved the issue for me.)K&F will definitely be first on my list if I need replacement lens caps in the future, and I definitely recommend them based on the quality and fair pricing.

The 58 mm was a perfect fit for my EOS 4 camera. The lanyar is a great add to keep the cap on the camera strap. The lens cover is at least as good as the one that came with my camera, and protects the lens well. It's easy to attach, good for its intended function, and is a terrific value for something that just works.We are really pleased with it.

I recently purchased the K&F Concept 62mm Lens Cap Cover, and I have to say, it's been a pleasant surprise. Finding quality accessories at a reasonable price can be a challenge, but this lens cap cover delivers on both fronts.First and foremost, let's talk about the cost. At such a low price point, I was initially skeptical about the quality, but I was pleasantly surprised by how well-made this lens cap cover is. Despite its affordability, it doesn't feel cheap or flimsy at all. The plastic construction feels durable and capable of providing adequate protection for my lenses.In terms of practicality, this lens cap cover is a workhorse. It fits my 62mm lenses perfectly, providing a snug and secure fit that ensures my lenses are well-protected from dust, scratches, and other potential damage. The spring-loaded mechanism makes it easy to attach and remove, saving me valuable time when switching lenses on the go.What I appreciate most about this lens cap cover is its simplicity. There are no unnecessary bells and whistles here – just a straightforward, no-nonsense design that gets the job done without any fuss. It's the kind of accessory that you can rely on day in and day out, whether you're shooting professionally or just for fun.Overall, I couldn't be happier with the K&F Concept 62mm Lens Cap Cover. It's affordable, practical, and does exactly what it's supposed to do – protect my lenses without breaking the bank. If you're in need of a reliable lens cap cover that won't cost you an arm and a leg, look no further. Highly recommended!

I have been shooting professionally (mostly Nikon and, more recently, Canon) for decades. Recently I lost or misplaced my 82mm Canon lens cap for my Canon RF 24-70mm f2.8 lens. Rather than pay an astronomical price for a replacement Canon lens cap, I decided to — based on favorable Amazon reviews — check out the K&F Concept 82mm lens cap. It arrived today and I immediately compared it to one of my 82mm Canon lens caps from another lens. Functionally, the K&F lens cap is every bit as good as my Canon lens caps. It is the correct diameter and has screw-on threads like the Canon lens caps. It goes on easily and is secure. However, it is not a copy. It differs in ways from the Canon lens caps that do not hurt its functionality (different spring mechanism, different interior design, etc.). Furthermore, while it does not have Canon emblazoned on its forward-facing surface, its logo is black and tastefully inconspicuous. If I lose or misplace this lens cap, I would buy another one just like it without hesitation.

I purchased the 49 mm size for my Fujifilm X100vi because once I added the AR-x100 accessory adapter ring and the 49 mm Chiaro Pro UVATS UV filter to add water resistance and lens protection to the camera, the Fujifilm supplied lens cap no longer works. (Who designed this?!!) The cap seems sturdy and the supplied leash is a nice add on that fit around the lens very nicely. For other camera setups, I'd purchased a clip that can hold a lens cap on the belt of my fanny pack, but it didn't grab lens caps sturdily enough. They would release from the clip when I sat down. The leash here keeps everything together and feels like nothing will come loose or fall. For me, it's a keeper. I know some people rely on the UV lens for total protection and throw their camera in a bag with no protection, but I've always used lens caps despite the slight annoyance of taking them on and off. Now having to worry about and find my lens cap is no longer necessary, at least for the Fujifilm X100vi.

Yup it’s a lens cap!! Works perfectly fine. Cost is great. Quality is excellent. Keep your front element protected.

The lens cap snuggly fits on the UV filter. The strap works well and I will get more for my other lenses. The problem is the lips you have to pinch to remove the cap are too shallow making it hard to grab hold of to take off. I will not be buying this brand again.
