Canon ET-67 Gegenlichtblende für EF 100mm f/2.8 USM Makro-Objektiv

Bought this to keep flare and glare off my macro shots, and it does exactly that without adding much bulk to the setup. The reverse mount for storage is a nice touch, makes it easy to toss in my bag when I'm done shooting.

The bayonet mount clicks on so securely that there’s zero wobble, and I’ve noticed it completely kills the flare I used to get shooting backlit flowers. It’s a simple piece of plastic but it does exactly what it’s supposed to—and it’s saved my front element from a couple of careless bumps too. Glad

After using this with my 100mm f/2.8, the way it blocks side light has noticeably improved contrast in my macro shots. It's a solid piece of plastic that fits perfectly without any wobble.
