Geez, I'm actually putting my money where my mouth is: last month I broke down and bought the Zeiss Touit 12mm f/2.8 for my a6000 (and now my a6300, too). Good thing I don't have a full frame e-mount camera yet, or I'd probably have to cough up the dough for the field of view equivalent Batis 18mm f/2.8. Sigh. Gear porn at its finest, from Las Vegas (NAB 2016).
