I heard of this method of doing mx but never tried it out before.
I took my lca out and fiddled with it abit...
What happens when the film rewind button is depressed?
The Gear ( 1 ) will not move/advance
But when the film has been loaded, and shots has been made...
The Take-Up Spool ( 2 ) Which has already collected the film, when you advance the film.
The film should continue to be pulled into the spool.
So the end result shld probably be the same, wouldn't it?
