I wanted a camera that was capable of better images than a cellphone and I have a lot of Olympus gear so the E-P7 seemed like a logical option. It doesn't do some things I had hoped like real focus bracket (there is an online review that claims it does but I have been through the menus several times and the best there is a the AP mode, but this is very limited). I am adjusting to no viewfinder. Image quality is great. I had originally planed on using my 12-45 m.zuiko but I decided pick up the 14-42 pancake (this lens is surprisingly good) to make is pocketable. I picked a mini tripos (Leophoto MT-03 and MBH-19 total weight is about 8 oz and goes in a pocket). I can use any of my other Olympus lends (but anything more than about 300 g doesn't make sense).
Absolutely fantastic take everywhere camera ! I already have an extensive Olympus camera system, but it's just too big & heavy to carry around constantly.
With the E-P7, I can use my Panasonic Leica lenses & get the same image quality as my EM-1's, but without all the hassle.
My only concern would be the lack of weather sealing, so it will be a fair weather camera !
