Late last year I tried two copies of the new 24mm STM lens on my 650D. Both times the AF was not consistent, actually was pretty consistent being a bit "off". But it was dead-on using live view. I returned both lenses. FYI, my 40mm STM lens AF is dead-on with my 650D.

By now, there are several reviews posted about this lens (none here) and I've not yet read anything about AF problems.

Is is it not a contrasty lens?  It misses focus on subjects with little contrast to work with such as in low light?  I think that is the issue with my 50mm f1.4 (and it isn't stabilized).  My 50mm lens also works better in live view because focus is achieved using different methods than contrast.

How well does it focus on well lit subjects with high shutter speeds?
