>>2699862Why not just adapt the Canon 11-24 f/4 L for E-mount? You'll get decent AF with the A7RII, auto IBIS from the lens data at all focal lengths (not that you really need it with how wide it is, but it's always nice to have), and it's fast. Sure it's expensive and larger, but it's also the holy grail of ultra-wide angles, primes included. Even though Canon has gone to shit with their bodies, their glass is still fucking amazing.
