K&F Concept 86mm Nano X MCUV濾鏡

Mounted this on my wide-angle lens and the 99.6% light transmission definitely helps with sharpness in low light. It threads on smoothly and doesn't add any noticeable color cast to my images.

I swapped it onto my 70-200 for a landscape shoot and didn’t notice any color shift or flare in the highlights. The ring threads smoothly, no binding at all.

I was a bit worried about stacking this filter on my lens for the extra protection, but the image quality stays crystal clear edge to edge. It's also super easy to wipe clean without smudging, which makes swapping lenses on location way less stressful.
