mamiya rb67? (question from a pentax 67 user)

[epatsellis]

easiest way is to by a as-is RB from KEH, less than $45.00, unscrew the bellows and racks on the sides, slide forward, figure out the best way for you to rotate the lens cocking lever, based on your fab/cobbling skills, mount it on a lensboard with some machine screws and locking nuts or tapped holes (use self adhesive foamie gasket, <$1 for a 8x12" sheet from wally world) put your lens in MLU mode, cock to open/compose, close, load film, fire shutter. pretty simple once you play with a lens for 5 mins, it all make sense.

Pentax 67 lenses

I own the 55mm f4.0 SMC. It is the sharpest lens I've ever used. I recently tested it using gigabit film and could resolve 156 lp/mm on the Air Force charts.

one thing that I wonder often, how does lpmm relate to image tonality and OOF smoothness, image sharpness is a give, naturally.

erie - how does one remove the bellows from the front standard?

I can't seem to work out how to do this while keeping the standard as complete as possible...

if you're not in a big rush, give me a week or so, still sorting out from the move, and I can post a pic of the front standard of a pro-s, with the holes hilighted. If you're impatient, fire the body, rack the standard all the way out, then remove the 4 or so screws holding the bellows to the body, remove front standard, then peek inside the bellows and remove the 8 or so screws holding the bellow onto the front standard (from memory)

Well, I'm not particularly impatient but that description should be enough for me to work it out anyway...

Thank you,

David.
