Lens that are Compatible with the Canon EOS 70D Dual Pixel CMOS AF

Canon USA has a list of lenses that will be compatible with the new phase detection system of the EOS 70D. You can find the official compatibility list  here:

And here is a list of lenses that have "limited" compatibility. These lenses will default to conventional contrast focusing when using live view

Note that as per usual, there is no mention of third party lenses (Tamron, Sigma, Tokina). There is no reason given for why some lenses are compatible and why others aren't, although the age of the design does seem to be a factor. If it were purely a matter of optics, then compatibility would be determined by what angle the light rays are hitting the sensor: if the lens design produces too extreme an angle, it is possible that the dual-pixel system would not work. However, since the system is rated to f/11 with compatible lenses, I don't think this is the case, as there doesn't seem to be any rhyme or reason if you look purely at the lens design.

In other words, the reason is probably to do with the lens CPU, possibly in melding the lens operation with the video. Up until now, lens AF would have tied into the contrast detect programming on the camera body for movies, but with the new 70D live view AF, the lens is being plugged into the phase detection logic instead. How much of a change, only Canon would know. It's all a bit scary if you are an owner of third party lenses, but there will likely be lens updates coming in the future. Hopefully.

Here are the lenses that have been deemed compatible as of July 2013. This list will likely change over time as lenses are updated.

  1. would be interesting to create a list with third party lenses. My Tokina 12-24 ist not working in 12 mm mode (Error), but ok when zooming to maybe 14 mm.
