you think a EF-M 22mm will focus faster on the eos-m than a USM lens on a body like a 7D/70D?...there may be something wrong with mine then...cause speed is definitely not it's strong suit...
i'm pretty sure malveaux doesn't just have FF, and M, i think there's a crop body in there
Yeap... several cameras, full frame, several APS-C's, and the EOS-M.
The EOS-M is by far the slowest AF system. The EOS-M lenses are not fast either. They're not USM. Also, a USM lens on the EOS-M still focuses faster than the EOS-M lenses. I used my 85 F1.8 with a generic fotodiox adapter on the EOS-M, and it still focused much faster than the 22 F2 pancake for the EOS-M did. EOS-M lenses are about as fast as non-USM lenses. They are fast enough for general purpose, but still slow. USM is simply faster. Even on the `M with an adapter. I did notice heavier, bigger USM telephotos were slow on the EOS-M too. But the smaller USM primes are snappy on the EOS-M. I only did it as a test. I use the 22mm on the EOS-M 99% of the time otherwise. And I find I use the EOS-M more and more, it has easily surpassed my other cameras for overall usage, simply because it's smaller, goes every where, is less obtrusive, and does the day to day stuff that I don't want to lug a big SLR around for (kid, outside, landscape, general walk around, travel, etc). I drag out my full frame for portrait. And my APS-C's for macro/wildlife and some secondary landscape, etc.
