I've played with a number of DSLRs this year - Olympus E-30, Pentax K-30, Nikon D600 - but couldn't bring myself to buy back into the heavy systems with outrageously expensive lenses. Yet ... I can't stop thinking about the feel of the grip in my hand. I have the OM-D with the grip, yet my hand still cramps up after holding too long. I find myself thinking of the GH3 and wondering how nice the bigger size would feel in my hand. I love the light weight of the µ43 system, but I'm think I'm coming down with DSLR-itis. Somebody help me!
