    Jake, this forum has resources. One is a list of useful links that includes a link to Cambo's directions for setting up an SC (that includes your SC 2). See http://www.largeformatphotography.in...mainly)-lenses, the link you want is under Cambo, which is under older modern view cameras.

    I'm sorry that none of the other responses so far told you to RTFM.

    An SC set up properly should focus a 150 mm lens well through infinity.

    I think I can put a 90mm lens on my Cambo with the tripod block between. I suspect a rotated front standard is the problem.

    Viewed from the side both standards should be identical, with the posts towards the front and the side pivot hinges toward the back.
    Thanks, but I'd rather just watch:

    Another problem with the Cambo SC /SC II is the bellows is not soft enough or wrong type to use much shift with a 150mm. It is good enough for use in the studio at macro distance +shift, but not for landscape or architecture. If you are not going to use lenses longer than 210 and no macro, a (long) bag bellows will do wonder. Take a look at the Arca-swiss Misura bellows. That's the ideal. Cheapest way to get a bag bellows is to buy from eBay, and replace the frames...

    Interesting if true. Why do you believe this? I ask because my SC 2 doesn't agree with you. With a 21 pleat standard bellows mounted it gets full rise/fall and full shift with a 150 mm lens focused at infinity. There are several standard bellows for the SC 2, I believe the 21 pleater is one of the longer ones.

    Why do you believe this? What's the point of destroying the OP's only bellows when he can buy a perfectly fine genuine Cambo bag bellows, used of course, from a seller on eBay? OP, if you decide you must have a Cambo bag bellows, look for a modern one made with relatively thick artificial leather, not an old one made of thin leather. The old ones can sag into the light path, the new ones don't.

    Good to read the bellows can be good. Mine where not- I almost destroyed it trying to take pictures of the mountains from bottom of a valley. Maybe the front mounting of my apo-something made the flange focal length a bit short??
    Presuming your bellows is not good, the frames can be used for a homemade bag bellows, else, keep it as Dan says. I had my Kardan 8x10" bag bellows made so it could be used with a 210mm with 30mm rise before starting to stretch. Never used, so when a local photographer asked to buy one, I was willing to part with it.

    Absolutely. Front mounting adds extension, makes the front-of-board-to-film plane distance shorter than the barrel lens' nominal flange-focal distance. The shutter's thickness plus the adapter's length. I use a number of lenses hung in front of shutters, but front mounting can be problematic with shorter lenses. Highly compressed bellows, as you've found, and the risk of mechanical vignetting.
