Re: 70d Focus issue with some lenses only

It is not about that.

Shooting in bright day at 1.4 was clearly showing the problem. A car at 20m for instance. Focus can be 10m front or 10m back at the next shot.

I see some comments here about other lenses tested. But testing a 17-55 2.8 is not relevant : focus problem is seen easily with small DOP. They still exist with smaller aperture but they are masked by the increased DOP. So you don’t see them. If you shoot with 2.8 or smaller aperture lenses, you will probably never notice it.

Take a car at 20m, at 1.4. Take 10 shots and see. If all are ok then your 70d is ok.

btw, yes, I tried with live view and all was fine. So it was not Lens related.
