Without filter / With filter photo. Super hard to tell if it's in or not. Stays sharp and great color. Don't know why people are having trouble taking it out. You can even just use your finger nail lol. My advice is to take photos without a lens while watching your shutter to see how and why it fits.

I do videography and with a 12-24 Gm I can’t fit any filters over the front.This was the ideal solution, however even though I shoot images and video indoors - I never need to change them around. The lightest tint gets the job done for me..That was until I needed to change it.First filter broke the glass when prying out with the supplied guitar pick (that’s kind of lame but thanks I guess), and than I was forced to use a shade I didn’t want to. I was installing it, and *plink* the second one but the dust.I’m handy, and work on a lot of expensive equipment. This was. It user error, this was terrible build quality.I really want to purchase more, but with how these couldn’t even be changed out and the risk of ass getting into the body of a camera I will not use anymore unless they send out replacements - I’ll update this if they do. I’m excited by the concept and the glass quality seemed great, but this was really disappointing.

I am a long time KASE user and I have used Kase Filters on my drone hyperlapses and and on landscape photos, timelapses, hyperlapses and video. They are just so good. This one in particular allowed me to use it with lenses that are difficult to mount filters on. And sometimes I just don't have the right filter size with me so I put this on there and any lens can now have the advantages of an ND Filter. Just be careful when installing and when taking it out. There is a serious risk there so be really careful. But if you know what you are doing, this is a really great product. I use the regular filters whenever possible. I don't know, I probably am just used to doing it that way, and some filters are not just for ND, I use fx filters and cpl so I need to use those front filters anyway. But, I always have this clip-in ND on my camera bag just beside my memory cards, as backup ND for when I need it.
