Sigma LH728-02 غطاء عدسة لـ 17-40mm F1.8

The bayonet mount clicks on so solidly that I don't worry about it popping off in my bag, and it's cut down the flare I used to get shooting into streetlights at night. Shading stays consistent even when I zoom through the whole 17-40mm range, which is exactly what I needed.

I was worried about the lens hood fitting correctly, but it clicked on perfectly with no wobble. The deep scalloped design really blocks out stray light, and I haven't seen any flare since I started using it.

Flare has been a non-issue since I snapped this on—the bayonet mount clicks into place with a satisfying, solid feel. It’s slightly bulkier than I’d like for tight bags, but the shading performance on my 17-40mm is worth the extra room.
