Actually improves the Sigma 150-600 E-Mount!
I'm usually against UV/haze filters due to concerns about their impact on image quality. However, I plan to use my Sigma 150-600 DG DN Sport (Sony E-mount) in fairly harsh conditions such as shorebird photography, surf photography and sports. So I gave in and bought this filter to protect the front element of the lens. In view of the fact that this K&F filter would probably be classified in the "middle class" in terms of price, I wanted to test whether it actually had an effect on the image quality. The attached image of a $20 bill was taken in exactly the same circumstances - 600mm at ISO 100, tripod with no OS. As you can see from the screenshot taken in the comparison view of my image editing software, the image on the right (with filter) is significantly sharper and has higher contrast. I am shocked! I fully expected to remove the filter if I wanted a better picture. Now I can leave it on 100% of the time and just wipe away any spills or dust without worrying about scratching the front panel. Strong recommendation!
