For those of you considering these cameras, Focus Camera and B&H are running promotions to get $300 credit for used cameras traded in when you buy the A7 or A7r.
Rented the A7r during a trip through Utah & Arizona; think I may jump on this myself if they'll take one of the p&s I no longer use. Will try to post some shots in the A7/A7r thread later when I get home.
I bought from Focus Camera because that $300 for any camera trade-in, even a non-working point-and-shoot, is stackable on top of the $650 ($200 without flash) Sony instant rebate, leading to $950 total off the package (body+lens+sony flash). Granted, that Sony flash is the HVL60M, which has known overheating issues similar to Nikon SB900, but it is still a top-of-the-line Sony flash and should work fine for casual use without continuous flashes. If needing continuous flashing, SPTS will repair it for $100. http://www.sp-ts.com/
One last thing, Focus Camera website does NOT list a package with body+flash+FE55mm, only one with FE35mm. So if you want the 55 mm in package, call focus camera and point them to their eBay listing package and order that one.
