K&F 46mm 經典藍色鍍膜 MCUV 鏡頭濾鏡

I was worried a filter would add bulk, but this one's super slim ring barely changes the profile of my lens. The Japan-imported glass feels solid, and the blue coating cuts glare without affecting color.

Spent a whole afternoon shooting by the coast and didn't worry once about salt spray or sand getting on the glass, the slim profile never caused any vignetting. The blue coating really cuts reflections too, colors came out punchy straight from the camera.

It's barely there on the lens—the slimness is what sold me, and it really does sit flush without adding bulk to my camera bag. The glass feels clean and sharp for daily protection, and I've already knocked the front element once with zero scratches to show for it.
