Kenko 1.4x Af Dg Pro-300 to suit Canon

[Roosta]

Has any one used this on a 70-200mm F2.8?

Any feedback on good/bad issues please.

I've used one on a 70-200 F4L. No noticeable difference in image quality just drops the lens 1 stop, still focused OK. - A good thing.

Thanks Russell, nice to know, The af is what I was wondering..

Cheers.:th3:

No problems with AF following footy with it - I reckon the 2.8 would be better again.

Yeap, Thats what I want it for, Photographing Rugby Union.

Thanks again.

Just got to watch the lens release button on the Kenko. It's easy to bump and a couple of times I had the lens turn and almost come off whilst using it.
