I'm interested, but I don't do pre-orders, so I'll wait for reviews first - and possibly that the price will drop a bit before buying it.
Otherwise, it's pretty much what I've been looking for: a lightweight full-frame camera that is more portable for trips than the Canon's crop bodies. I will still use the Canon's larger bodies closer home for better handling, but on trips, this is about perfect.
Especially if they get a 35/2 and a 85/2 (or 1.8s) out soon the A7 will be darn good for holidays, able to tack about anything I can think of and still be lighter to carry around than an APS-C body with 28/1.8 and 85/1.8.
Actually, thinking about it, I may sell the 28/1.8 and 85/1.8 soon.
