Protecting my lens
Bought to protect my lens. Don’t seem to detract from picture quality. You can use both if you want. One screws on to the others. The polariser gives a richer colour to shrubs and green stuff. Nice little carry case to protect when not in use. Keep the uv filter on all the time and it does not detract from low light performance.

I have other K+F filters for other lenses and they have been exceptional. I ordered this duo for the Sigma APS-C 18-50mm F2.8 zoom which I use on my Sony A6000. If I stack both filters together I get strong black corners. If I zoom from 18mm to 19.5mm they are gone. If I use one filter at a time no problem. So I have decided to leave the polarizer on for the summer and re-install the UV in the fall. Unless I plan to shoot 20-50mm on a particular day. These filter rims are so thin I dont believe there is anything in the marketplace that could improve this situation. I have stacked K+F on other lenses with no issues. Must just be this Sigma lens design.
