Fits perfectly

Great for jogging or cycling.

Well-made glasses, solid and perfectly functioning

I love these glasses! I have bought several as gifts too!

I have this ultra-low reflection uv filter in three sizes! It is very well made, easily threads on the lens, and provides great UV protection as well as preventing my actual lens from being scratched. Great value for the price! Picture quality is great through the filter. I use this filter for everything outdoors.

If you want to see what shooting with this filter looks like and you wear glasses, just get your glasses really dirty with drywall dust. Everything becomes softer and less detailed. If that's the look you're after, this filter has it in abundance. It's a well-made filter and doesn't cause any optical problems (apart from the intentional blurring). No color shifts or additional scattering. I didn't notice any noticeable vignetting on the 82mm version either. The knurling is also well done. I am impressed with the quality of this filter and will be looking at other K&F filters in the future.

You can get the same effects using your computer programs but I like to do things “old school” by using different filters to achieve the desired effect. This filter works well.
