No dual pixel AF goodness for 3rd party lenses?
Jul 5, 2013

OK, this has me a little alarmed:

Dual Pixel CMOS AF will work with 103 current and legacy EF-mount lenses, encompassing most of the company's modern lens family. The few lenses that can't take advantage of on-sensor phase-detect focusing will fall back to a legacy contrast AF system. You can't choose this system through the camera's menu; it will simply turn itself on when the camera detects an incompatible lens.

From here: http://www.digitalcamerainfo.com/content/canon-eos-70d-first-impressions-review

Could Canon be trying to cripple 3rd party lenses? I really hope not!
