Just had a rather interesting day spent with a couple of the Canon reps.. Basically iv got to play with the new EOS-M.. Build quality is very good, it has a touch screen which is pretty much the same as a iPhone ( very good even tho I strongly dislike touch screens on cameras ).. The only downside to today was I wasn't able to try it with either the standard kit lens or with the EF adaptor.. Ill uploaded some pics.. If you have any questions just ask..
Update.. For some reason I cant upload the images to Canon Rumors so Ill add them to my flickr
Nice. This will be my mirrorless camera.
