DS. DISTINCTIVE STYLE Rubber Lens Hood Anti Reflection Reversible Collapsible Lens Hood Compatible with Nikon/Canon/Pentax/Sony 50-65mm Camera Len...

This fits various lenses fairly easily and I did like the ease of moving the hood in and out (expanding and collapsing it) but therein lies the problem. The silicon hood is so thin that at the seams (folds for expanding and collapsing) it is thin enough to easily transmit light through it. This defeated the whole purpose of using the lens hood to block out environmental light to eliminate shadows from glass windows). I tested it at night shooting through the sliding glass door to the back deck and a darkened backyard - with the room light set to normally bright conditions. What I found was that the thinness of the hood's material allowed light to penetrate the seams of the hood and cause severe reflections on the glass even with the hood completely sealed against the window. While I liked all other attributes of this hood (I was testing it against another brand and this one was easier to fit on the lens and easier to manipulate) however, the inability to block out the ambient light was a fatal flaw producing image failures.

I purchased the 50 to 70mm lens hood for my 67mm Canon lens. I followed directions for product installation and it tore. It was too small for the lens, and the silicone didn't have enough give to stretch around the lens. I'm pretty disappointed.

I used this while flying out to the west coast so I could take pictures from the plane. It cut the glare and I was able to get some great shots. Just make sure you get the correct size for your lens. I ordered one for my Canon 50mm a nd ended up using it on a Canon 24-105f4. It was way too tight so I cut it a bit for fit.

The plastic is too think and low quality, it ripped really easy as I put it around the lens

The hood worked perfectly in a museum, took plenty of reflection free photos.
