B+W MRC MASTER 007 クリアフィルター (55mm)

Finally got around to putting this on my main lens and it's so transparent I keep forgetting it's even there. The German build quality is obvious the moment you handle it, threading on smoothly without any wobble. Sufficient peace of mind for everyday shooting without affecting my images at all.

The clarity is genuinely impressive—I can barely tell there’s glass in front of the lens, which is exactly what I wanted for pure protection. It screws on smoothly and hasn’t added any weird color shift to my shots.

I was a bit skeptical about spending this much on a simple clear filter, but the lack of any color cast or reflection is genuinely impressive. The glass is crystal clear, and it doesn't degrade image quality at all.
