Canon EW-65C 鏡頭遮光罩（適用 RF 16mm f/2.8 STM 鏡頭）

Took it out on a rainy walk and the petal shape actually kept the droplets off the glass without any vignetting in my shots. It clicks into place with that satisfying lock, so I don't worry about it popping off in my bag. Exactly what I needed for the pancake lens.

I love how this hood screws on perfectly without any wobble—makes a big difference for such a compact lens. It cuts down stray light nicely and still lets the camera fit in my bag easily.

I was worried about flare with this wide lens, but the hood fits snug and cuts out stray light from the sides without adding much bulk.
