I was just waiting for someone to tell me this. LOLI was going to recommend the A7s as well. It locks on in low light with f/4 lenses no problem. I actually tried it last summer in the stock room with the 70-200 mounted of the GAS Pusher (camera store.) I was shooting and locking on stopped down to f/8 with ISO between 25600 and 102400. Really impressive and if Sony put out a replacement in the future with at least 16MP I'll buy one as my everyday camera no question.
Need loan shark. ROTFLMAO
Seriously to stay in the FE mount this maybe the answer. This is becoming a math issue now.
