Building a complex lens approaching the performance of the RX1's 35/2 probably would mean a substantially larger product. While many of us would have bought such a lens, and paid up for it in price, size, and weight (guilty!) did Sony back off for reasons of competition either internal (RX1) or external - continual harping on Sony about "large" lenses? I'd have loved to have heard those design discussions.
I bought one because performance looks decent and I want a mix of AF and MF. As for speed, given I only had one RF lens faster than f/2.8 and all were more expensive than this one, a f/2.8 35 doesn't feel completely foreign.
