I found my 20D + A16 give front focusing at 17mm. This happens consistantly at the center focusing point. The other points seem better. I tried another A16 with same results. However, this does not happen with 30D + A16.

Does anyone have similiar experience?

Thanks.

your meaning of 'front focusing' is not clear

I mean the focus is not right at 17mm. The subject is a little blur. The camera focuses somewhere in front of the subject.
