Sure. There are a few big differences between the A7CR and the A7RV that you'd have to be comfortable with. That's the price you pay for having something much smaller, lighter and cheaper. One is the EVF and screen. The A7CR doesn't have the amazing 9mp EVF of the A7RV but just a 2.3mp EVF which is also smaller. The screen is 1mp rather than 2mp. I find this just fine as I mainly use the screen. However, for people who normally use the EVf they'd probably notice a big difference. The other big difference is the EFC shutter which limits the flash sync speed to 1/160th.
