TTL Blitzen

[Manualman]

no, TTL (through the lens) does not work with analog lenses.

I have no problem with TTL flash and legacy lenses. That applies to my Olympus m4/3 (Olympus RC flash) and Sony A7R3 (Nissin Air 1 system flash). I only use old glass and Laowa on the Sony. This is mostly for close-up and macro.
