Hey Cal,
Thanks for the response and the great deal on the A7! Looking forward to getting it. And congrats on the A7R purchase. I thought long and hard about it but I do a lot of intimate landscape work with long lenses so the shutter shock issue was a bit of a deal breaker for me, particularly at the higher price. Once the price of the R comes down I might pick one up or finally cut the cord and sell my 5Dii to get whatever comes next. For now the detail level on the A7 will be enough for me I think.
The ZE lenses are too rich for my budget right now, and much heavier than I would like. But I know they're amazing and would love to pick up that 21 one of these days. I'll most likely look at the Contax ones for now. Seeing good things about them on here.
Best,
Colin
