Hello, I'm looking for a wireless remote that will just control the shutter on my canon 30D. I really don't need it to do other things, though anything else would be icing on the cake. You'd think that this sort of thing would be easy to google search, wouldn't you, but there seems to be something about the 30D that makes it difficult to find a remote. I'd also prefer something that works on as many canon models as possible, for someday when I upgrade from the 30D. I did find this, can anyone confirm that it does indeed work with the 30D? Or tell me why I shouldn't get it? $26.00 does seem awfully expensive for just a shutter control, though.
