I bought the backpack for a Canon EOS R and a Nikon Coolpix P950. Both cameras, various lenses, spare batteries and chargers have enough space in the backpack and, if necessary, the compartments can be rearranged thanks to the Velcro.
The backpack makes a solid impression and the zippers work perfectly.

I was pleasantly surprised with how much I liked this pack, as I was not all that familiar with K&F's products. The pack seems very well made - the stitching and zippers are usually things that make a product seem cheap, and they are both quality. The materials all seem durable and the pack is actually quite comfortable. I've not worn it for an extended period of time but the shoulder straps and back padding are both very comfortable. The pack has a ton of storage - more than I need to be honest, but that's not a bad thing at all. Full disclosure; I use APS-C cameras and lenses so if you're running full-frame with tele lenses you're going to have a lot less space, but should still have enough. My only knock would be that I wish there were one or two more dividers included, just for small APS-C cameras/lenses.

This filter, if nothing else, helps keep my marriage on an even keel.Now I won't rehash the old UV vs non-UV filter debate, but personally I don't really feel I need a UV filter on my DSLR lenses, and if I were the only person using my cameras I wouldn't bother at all as I'm extremely careful with all of my equipment. My wife, on the other hand...Every time my wife takes out one of my cameras she treats it the same way she treats her sunglasses (lenses down on the dashboard of her car, jamming them in her pockets without a case or a second thought, smudges... just... everywhere. Oh, the humanity). When it comes to optical equipment she's history's greatest monster, a true menace to glass, but complaining about this to her will only ever end in a resentful argument.So the solution? A high quality UV filter that will protect my lenses without reducing image quality. I've tried cheap filters in the past that I've ended up removing every time I take a shot because there's noticeable degradation in the results, but as this is a high quality filter I can't see any different in the final product with or without the filter. All I see is a clean, scratch- and fingerprint-free lens coming back to me safe and sound, and that's worth its weight in gold.

D200, D7100+SMC Takumar 24mm 28mm I tried it in 55mm but I could use it normally. I don't know about other cameras or lenses but for now I'm satisfied. Endurance is unknown, but it is unlikely that this will break her.

have a few of these K&F adapters for mounting various vintage lenses on my cameras - I use Canon and Fuji ASP-C and M4/3 cameras and they are brilliant on all 3. Great price, well made and they work really well.

It has no ports but I can still use Canon lenses on NX cameras... Can enjoy different angles.

The adapter allows the use of AF or MF Minolta/Sony A lenses on Sony FE mirrorless cameras. Very well done. The lens can only be used with manual focus, but is fine in most cases. There is an aperture slider that isn't marked with f-numbers but with click stops so you can count stops if needed. It serves its purpose and allows me to do some vintage reviews of Minolta SLR lenses.
