Well, I got to play with a pre production eos m today at the canon stand at Rutland Water birdfair. Mounted on it was the eos adapter and a 40mm pancake, and that was all they had. First impressions of the body were good, it felt very nice in the hand and felt well balanced with the 40mm on the adapter. Build quality is good. I was hoping to see the video in action, but as usual, no cards were allowed to be put in and they didn't even have a demo card to show the video capabilities. All I was told was, it's the same as the 650d! The touch screen I liked, nice and responsive. Though I did find the camera slow at updating the image on screen as I went from light to dark areas. Touch to focus and shoot is a neat idea and it seems to work well. Menu system seemed decently layed out. The only main problem I found with it was it focus speed! Nowhere near as fast as the likes of my dad's G3 along with the Nikon J1 and V1 that had a play with today. Of course this was just a pre production model and nowhere near finalized, and also an ef lens on the adapter, but I expected the focus to be quicker. I look forward to seeing a full review and actually playing with one when they are officially released with the dedicated lenses. But for now, it is down at the bottom of the list of mirrorless cameras for me to considor.
