I have used Canon DSLR's for about 12 years before switching to mirrorless, i got fed up of the bulk of a DSLR and found myself leaving my Canon 60D at home most of the time, unless i was specifically going out to shoot, i switched to the EOS M system purely based on brand loyalty and i took it out with me more but i missed the OVF of the DSLR, so have recently switched to the Olympus OM-D E-M10 too, i was concerned about the EVF at first as earlier mirrorless systems EVF was poor, but i found that on the E-M10 is very good, my camera always leaves the house with me now.
