Selling my OM-D and returning to 60D

Buy the Panasonic GH-3 or the GX-1 if its a camera thing OR get the 12-35 2.8.

They will have a 42.5 mm 1.2 on the way too.  If your ready to go to the Canon DSLR the Panasonic GH-3 should be even easier to use since the physical size of the camera does not matter to you.
