Teleconverters Is a teleconverter (e.g., 1.4x or 2x) compatible with a Canon EF 70-300 1/4.5-5.6 lens? I know I won't be able to use AF, but will work with MF? Thanks, Rob

It's not compatible with that zoom lens. It's compatible with the 70-200L f/2.8 and the 100-400L f/4.5-5.6 and the L series fixed telephotos of 135mm and above. You can use autofocus as long as the lens that you put it on has a max aperture of at least f/4 with the 2x extender. Manual focus will work as long as you can turn the focusing ring.

Canon's and Sigma's teleconverters will not fit that lens. Their TCs have an extended front element that nests into the rear of a select few compatible lenses. Kenko and Tamron make teleconverters that will fit and do work with the EF 70-300. AF will be unreliable if it works at all, and the viewfinder gets dim which hinders manual focus, but it can be done.

Thank you all for your advice. Product descriptions many times don't tell you these things. Regards, Rob
