IMVHO Merrills aren't the same thing. Ok they're cameras

but they're fixed lens cameras and unless you love the focal length you need multiple cameras and then there's the little operational issues that make any A7 series camera look like it was designed and made by God, on a good day.
Good and cheap though Merrills are they fixed lens APS-C cameras with a host of operational issues and personally I'd rather have my Panasonic G1 forever... Merrills have their fans but personally they're not for me and I just can't see many people who are seriously considering an A7 series camera considering a Merrill unless one is to compliment the other.
