On the surface, I love the concept - a FF camera nearly 400 grams lighter than a D610. Fantastic! But am I the only one that thinks this is a bit of a shell game? With a CIPA battery life of only 340 shots, vs. the Nikon's 900, I'd be investing in a battery grip for the Sony just to keep the battery swapping down. Then you'd still want one or two more batteries on hand in addition to the two in the camera for a full day's shooting. It looks like most of the weight advantage goes away. Same issue applies when comparing a D7100 to a OMD-EM1 (although of course the lenses are a different issue in that comparison).
But I suppose if you didn't mind swapping and went without the grip you'd still have a significant weight advantage. Bravo to Sony for innovating! I love my D7000 but Nikon needs to pay attention here!
trac63: I think the price, size and weight are going to be deal-breakers for me.
Quite frankly, if I were in the market for something like this I would spend the extra money for the Nikon 24mm f/1.4, and I'm not even a Nikon snob or anything. Two of my favourite lenses are Tamrons.
I dunno, if you get the eqiv of a 18, 24, 28, and 35 mm prime in one lens, I suspect that will make for a lighter kit overall.
But of course, there's no substitute for how the camera feels with a light prime on it.
It all depends on how good the out-of-the-box experience is. If you can pick up a GH-3 turn it on, and get pleasing shots right away, this should work great. But if it requires even a few tweaks before you get good jpegs, it could backfire.
Awesome. Makes perfect sense. I wonder how long it will take before most cameras take this approach. Would love to see an android based DSLR.
