Now you've got the bellows don't buy a 25 inch TTH lens and discover that you can't reach the lens while you're looking through the ground glass. Like I did.
Took it out today with a 19" Artar. Couldn't reach the front standard from behind the ground glass. With my long arms, that is definitely a first for me. But I FINALLY got to use my 19" Artar! I'll develop the films tomorrow and see how badly I screwed up.
