I've taken a roll of Konica 200 (colour neg) on a Minolta SRT100x. I used a PX625 battery (1.5V), but realised - towards the end of the roll - that the shutter speeds were really high for the low-light scenes.

Checking with 2 Nikons indicates the Minolta is up to 3 stops too generous (i.e. I've given up to 3 stops too little exposure).

So what should I do? Send it for 3 stops push processing, or 2 stops, or what? Thanks in advance.
