Focus peaking works with anamorphic preview, but only with "blinking dots" display selected.
Working like a charm!

I just miss the anamorphic preview in play mode now, but that can certainly wait.
I've been using the Alpha 3 for three days in a row, shooting a short film all day long - no resting times for the camera - with many lenses (m42 adapted, 24-70, 70-200, 50, 16-35), multiple cards (and brands) and custom cropmarks without ANY bugs, quirks, errors and such. Congratulations, guys! Your work helps a lot! I'll certainly donate some more soon.
