Canon 2x converter with 70-200 f2.8 lens version II
Jan 3, 2012

Hello

I went to my local camera store yesterday and had them mount the canon 2x mark iii converter on the 70-200 f2.8 mark ii lens on a 5d m2 body.

I played around with the combo and I noticed rather fast focusing.

I thought that the converter was supposed to slow the auto focus down substantially.

I did not notice this.

Any thoughts and anyone with experience using this combo?

What about deterioration in quality? What has your experience been?

Many thanks
