Got this filter set for my R6 to use for a variety of things. First off, I lost my lens cap a long time ago and have been wanting to try a magnetic one for a long while. Fortunately, one of the options in this kit IS a lens cap, which is super convenient.

I run a 35mm prime lens for like 80% of the stuff I shoot, and so I already had a lens ring adapter that I used for my VND filter, so slapping that on, and then screwing in the base magnetic mount, I was able to easily get a lens cap!

A far as the quality of everything, it is all top tier. K&F is generally pretty respected in this space, and all of the lens kits are of high quality. The threads are smooth, motions are smooth, and the magnetic fitment between the lenses is really nice. I would say with a lens stack up like this, you are definitely more likely to get dust stuck between the outer filter and your real lens, but nothing a blower can't fix.

The image quality coming out of these is great, as you'd expect and hope for filters at this price, so I was happy with that. I don't think I'll use the black diffusion filter much, but both the CPL and the ND filter are quite useful. I'm happy to see they did not include a useless UV filter, like some other kits, and instead have a set of very useful filters. Granted, the ND32 isn't a lot of light filtering, but it can be helpful if you just need a slight tweak to get your frame rate or aperture right.

Overall, its very expensive, but I really like the kit, and it comes with a really nice organizer for them. Lens cap is awesome, and the magnets make me never want to go back to threaded filters again.
