I like the RX1 a lot, but center sharpness gets A LOT better when stopping down from f2.0 to f2.8 or f3.2. At 100% view, this is fully field relevant: Details and sharpness at 2.0 are okay, from 3.2 they are brilliant. I must admit to be somewhat disappointed by that. Does this practical view fit to Your lab results (which are somewhat abstract to me), i.e. is that "perfectly normal" or did I get a bad copy ?
