Product DescriptionSpecially designed lens hood for the CANON EF 75-300mm f/4.0-5.6 IS Lens (CAN ET64II)
Works reasonably well, but pricey (Rating: 4 out of 5) I added the ET64II lens hood after several weeks of shooting with the EF 75-300mm USM lens. Though I didn't often run into problems with lens flare (outside of when I deliberately wanted it for creative effect, that is), on several nature and plane photographs I found myself in need of a lens hood.
This one works fairly well. Using it for a day of nature photography in varied lighting conditions, I didn't have a single problem with unwanted flaring. Plus, it also works with my EF-S 18-55mm kit lens that shipped with my Digital Rebel XT, a minor plus.
However, it's a bit pricey for what it is and for the average price of the lenses it works with. It's not petal-shaped due to the rotating end of the lenses it's designed to work with, and if you for some reason change filters often or are using a circular polarizer (which on the intended lenses is somewhat problematic anyway due to the element rotation during focusing), the hood gets in the way.
Canon ET64II Lens Hood (Rating: 4 out of 5) This Canon lens hood works well and can be put on lens backwards for easy storage. Reduces sun flair when shooting on bright days. However the photo on Amazon's web page in incorrect. The actual hood has a flat surface on both the top and bottom. The photo shows a hood that is flat on the bottom and has several parabolic indentions on the top surface.
High quality (Rating: 5 out of 5) I've used this lens hood for over a year. It fits on easily and firmly - never falls off. With this, you don't need an extra (UV) filter for protection of the front lens. When put on the reverse way, for storage, it nearly covers the entire lens barrel, protecting it against rubs from other equipment.
