Query on 7D + 300mm 2.8 + 2x - does AF work?
Hi,
I currently use a Canon 7D along with a canon 400mm f5.6 prime. A TC does not work effectively on the 400mm f5.6 as AF goes for a toss. Now, I have been hearing that a 300mm f2.8 is one of the sharpest lenses around, but wanted to know about the image quality after adding a canon 2x on it. Also, is the set up even compatible with the Canon 7D where AF still continues to work reasonably well?
I have heard that 300mm is good on a 7D from someone once and also that 300mm works great with a 2x from someone else. But never in the context of it working well on a 7D without compromising on the AF and image quality.
Can anyone of you please post any experiences you have on this set up or please share any advice you might have?
Note: I cannot afford a 500 f4 lens!!
