Ok, so more questions since I have Hassies on my mind. Since the film is much larger I know (I think I do atleast) that the lense acts opposite of a digital camera lense i.e. 20D when the sensor is smaller. Like.. since the 20D has a small sensor the lense acts larger. With a medium format the lense should act much much wider correct? So like the 20D it's focal length multiplied by 1.6, what is it for medium format? I hope I'm making sense and I hope it actually works like I think it does. Haha thanks for putting up with my random late night questions that make no sense.
