Anyone get their 5DMKIII to AF at 1400mm, I have.
Ever since the Firmware update which allowed the 5DMKIII to AF at f/8 I have been playing around with coupling extenders and I found that when I attach the Kenko 2X Teleplus Pro 300 to the 5DMKIII and then attach the Canon 1.4X II extender to the Kenko then both to the 500 f/4 IS L Series 1 that I can get AF at 1400mm. with good quality images. I use the central square focusing pattern with all squares with a dot in them I get very good results. Forget BIFs but I use it for distance shots on my Gitzo. By the way the Camera reports this combination as f/5.6 in the viewfinder.

I'd appreciate it if you could post a 100% RAW file crop of a nice frame using this setup.

Me too! I've stacked the Canon 1.4X Mark II extender and the Canon 2X Mark II extender on my Canon 500mm f/4 Mark I lens with the 7D and focussed using Live View. The quality of the resulting images was barely acceptable.

I have tried this setup on my 1DMKIII but no luck. I am house bound at present thanks to crashing my Velocette 500 in last month's Vintage MC races and I have a shattered Patella but I will try to shoot some birds next week, I have the 500 set up in my Laundry at present.
