>>2987931AF is dick-splitting quick on the 35mm f/2 in good light, and slowpoke tier at EV3 and below. Dunno about any other lens. The battery that came with mine was kind of miserable, but OEM ones from China were much better at like 1/8 the cost (~20 eurobucks for two). Only problem I've had was contact trouble between lens and body, but that seems to have gone away after cleaning the contacts w/ a q-tip.
Adapted OM-system and m39 lenses work fine.
Detail on the no-AA x-trans sensor is phenomenal. This makes the Acros film simulation extremely pornographic (pic related).
