Review title: Doesn't work with Canon 7D.
Product review: Although it says it works with the 7D, it wouldn't work with mine. I don't know if the unit is defective or isn't advertised correctly, but even with all the AF and timer settings as they should be, the release does nothing. After doing some more research, I am getting the Opteka R-4, since it's compatible, wireless, and cheaper.
