I've been a bit negative, if not absolutely nasty, about the large size and high price of the GH3. Compared to some smaller DSLRs, the comparison really is shocking. But I'm warming up to this monster. I've thought of maybe getting an E-PM2, E-PL5 or G5 as a backup in case something weird happens with my OM-D, but I'm finding the features of the GH3 very compelling. OLED screen and EVF 3 custom settings accessible by dial 5+ customizable function buttons large comfortable grip 3D / multi-process noise reduction Interval timer built in Articulating screen rugged build very nice control layout You know that big kerfuffle about the iPad Mini not having a Retina Display? That's me and OLED screens. Anything less is unacceptable. I'm spoiled by OLED. The sensor in the E-PM2/E-PL5 is compelling, as is the grip & articulating screen of the G5, but the lack of OLED screen really makes a difference for me. I know I shouldn't judge an image by the screen, but I end up shooting with the screen (rather than the EVF) 90% of the time. When what I'm seeing is uninspiring, I really don't enjoy shooting - it's that simple. The OLED display on the OM-D (and sensor to match) has been a thrill and has transformed how I experience photography.
