I just recently did a trade with a fellow APUGer and I ended up with a nice selection of Mamiya lenses and a good quality body.

I have a question about the Mamiya 80mm 2.8 leaf shutter lens. The leaf shutter can be cocked to preview the image (to actually see an image in the viewfinder) and Ive figured out how to do that, but is there a way to keep the leaf shutter cocked and locked in the open position so it does not have to be manually cocked after each subsequent frame?

Im a little confused and dont want to fool around too much with this new (to me) lens and body combination for fear of messing something up.
