m43.eu posted a great side by side autofocus speed test of the Olympus OM-D E-M5 vs the new Canon EOS M. Canon have arrived late to the mirrorless party and the EOS M is a hot seller, but the camera itself is less than impressive in a lot of ways – particularly it’s pitiful autofocus performance – and has become a bit of a joke in mirrorless circles (witness the hilarious video below from The Camera Store in Calgary, Canada).
The EOS M is a decent camera, and in some ways, it does show some promise. But when you stack it up against an OM-D E-M5, it shortcomings become even more apparent, and at $900 USD, there are a lot of other (and in our opinion, better) cameras that we would recommend before you pick up an EOS M, such as the Panasonic Lumix G5 or Panasonic GX1 (only $450 USD, half the price of the EOS M and a real bargain at the time of this posting), a Sony NEX 5R or Sony NEX 6 or an Olympus PEN Mini E-PM2, Olympus PEN Lite E-PL5 – or just go for the OM-D E-M5. Looks like it’s back to the drawing board for Canon.
If for some reason your heart is set on it, you can Check out the Canon EOS M Here. Otherwise, grab one of our recommended cameras >> Panasonic Lumix G5 (which is still small, but has a more DSLR-like form factor), Panasonic GX1, Olympus PEN Lite E-PL5, PEN Mini E-PM2, Olympus OM-D E-M5, or the Sony NEX 5R, Sony NEX 6.
