Haida 105mm UV Protector II

The threaded metal ring is precisely machined, so it screws on smoothly without any binding. It’s already saved my front element from a splash of mud while hiking last weekend.

Finally got this filter for my 105mm lens, and the fit is perfect—no wobble or looseness when screwing it on. I've already knocked the front element against a doorframe, and it took the scratch without any damage to the glass underneath.

I was worried about the 105mm size being too bulky, but it screwed on smoothly and feels solid without adding much weight. The glass is crystal clear—I've left it on for weeks and haven't noticed any image quality loss.
