Wouldn't say that I was in the market for an FF camera. Many factors would have made this a no go. I sold my 6D as it was too big and heavy, so glad to see it is much smaller and lighter. Anyhting approaching the M5 is size would have been way too small for any larger lens, so that would have made me say no. The size is just a bit larger than the 77D - and very similar to my Olympus E-M1, so that really seems perfect for me. Since the lenses will have IS, IBIS is a complete non-factor for me (and I presume a very large percent of new buyers, who do not have older lenses). Eye-AF is something I would turn off immediately anyway. Two slots would be nice, but I expect one - and that is perfectly OK. Glad it soes not have too many MPs as well! If the price is really around 2K, then I may have to sell some of my old gear to make room for this one!
