I don't know that one. I have never done the mirror lock up thing yet, with or without the winder.

do you still have to wind a new film forward till (1) appears in the film back window using the little film winder handle on the film back or can you put a new film in and fire the shutter via the motor drive untill (1) appears in the film back window?
You can do both. I do the former - saves battery power.
