    Super Angulon 90mm/f8 on Sinar DB for 5x7 vignettes or not?

    My 150mm lens has a little movement on my Sinar P. Sometimes it's not wide enough for architecture shots. A Superangulon 90/f8 would be a lot wider. Not much movement, on 5x7 anyway, but on a DB board with Sinar shutter will it be vignetted? Usually these lenses are mounted into the bellows not ahead as with a DB mount. I'm pretty sure this approach was intended for 4x5 where it is far less wide. I have a 4x5 kit for the Sinar but if I could use it with the shutter I have for 5x7, that'd be much more attractive. Thanks for your help.

    I've never posted and gotten zero responses before. No one else has tried this?

    My SA 90mm will not cover 5x7 on my Norma. I've been told that the old Angulon 90mm will just about cover 5x7 but I've seen no evidence.

    My f/8 90mm Super Angulon covers 5x7 at f/22, and the Schneider lens data states that 5x7 is the recommended maximum format size. Placing the entire lens forward of a Sinar shutter, your primary problem will be compressing the bellows enough to focus, I would think. If your 90mm SA is in a shutter, then I would skip using the Sinar DB shutter.

    Thanks. It might be worth it even for 4x5 where I have the bag bellows. I will do some measuring. I'm not in a hurry to make a bag bellows for 5x7 but I might. The plan would be to buy this in DB mount for use with Sinar shutter.
