I'm not defending canon, I'm saying that people didn't cause an uproar then, so canon didn't know it would be an issue. Basically, canon has a habit of testing some of their ideas out on lesser cameras before rolling them out on the bigger lines to make sure people like them and to iron out the kinks. Why do you think the 1Dx AF is in the 5D3 FIRST... But since no one complained when the 7D was launched, they probably assumed it wasn't a big deal. It obviously is, I just hope it's something that can be fixed via firmware.
Its cool man, i just never followed the thread on the 7d because i didn't need it but i will say this as a side note, the 7d locks focus even beter than my 1dm3 at least at the center point. I go thru hundreds of thousands of images during a summer and the guys that shoot for me that have upgraded to the 7d have had higher hit rate percentages since the upgrade and fewer misses like my 1dm3 can at times. I am super impressed with it. I know the sports photographer owner of Actions Sports Images personally and he has been shooting the 7d instead of upgrading his 1dm2n bodies. He would like to still use the m2n's but he is sick of repairing them and he wants more buffer these days.
