I'm not the first to say it, but K & F makes some nice lenses and this collection for the Osmo Pocket 3 is no exception.

I'm also not the first to say it (since I read some other reviews!) that I wish I had at least one more stop on the ND filter. (It's been my experience when I want to shoot outdoors at 1/50th and 24fps--when I'm being all "cinematic"--I need at least six stops on a sunny day. This ND filter stops at 5. It's been my experience that that's just not quite enough. (In fairness, some people think the 180 degree run is too pretentious with a device like the Pocket 3 and that you should just set it on full auto and be happy what the camera gives you.)

My only other "challenge"--and this is the case with any variable filter I use on the Osmo Pocket 3--is adjusting the lens delicately enough not to make the gimbal fight back a bit. It's a very delicate procedure and I feel very ham handed when I try to do it. This is certainly not K&F's fault. It's just the nature of this technology. And my fumbly fingers, I guess.

All that said, this is a fine set of filters for the Osmo Pocket 3. I love that you can close down the camera on most of them (save the wide angle lens) without having to remove the lens. But I also admit that I may not be hip enough to completely appreciate what a black mist filter does. Glowing highlights? (The softer skin affect, I get.)

The only other difficulty I ran into was getting wide angle lined up correctly. You really have to make sure its lined up right before filming or the images will come out soft or blurry...and you may not be able to see that softness in the camera's tiny monitor. (At least that's what happened to me.)

Still, a pretty decent set. Maybe the younger people with skinnier fingers are better with the variable filters.
