ProMaster 27mm UV Haze 紫外線濾鏡 (8193)

Screwed onto my vintage 35mm lens perfectly and the 27mm threads were exactly what I needed. It’s already cleared up the haze in my outdoor shots without any weird color cast.

I was worried a thin filter would interfere with my lens cap, but this one is stackable and fits perfectly with no issues. My outdoor photos have noticeably less haze on bright days, and the UV absorption really does clean up the distant details.

This 27mm filter threaded onto my vintage lens without any issues and the glass is clear enough that I don't notice it's there. It blocks enough UV to cut down the blue haze on sunny landscapes, a nice bonus for the price.
