Well, it turns out I actually DO HAVE a Cambo Wide with a 65mm lens panel!
My memory sucks, I thought I sold it. I guess I just sold the 90mm lens panel with lens that I had, but didn't sell a Cambo body.
I would like to get $1,500 for it. You could sell your 75mm lens on eBay if you wanted to go with the Cambo and it's 65mm. In 4x5 the difference is not huge, and you have a bit of leeway in framing and cropping. I believe the 65mm is a Schneider Super Angulon.
The Cambo Wide is fairly similar to the Fotoman in many ways. It is also a solid body camera with a fixed/rigid lens cone. The Cambo actually has 10-15 mm of shift/rise that the Fotoman does not though, which can be a plus.
I will pull it out and get you a description of the body, lens, etc, along with a couple of pics. Send me your e-mail address via the e-mail function of the forum here, then we can chat offline.
If you want to hold out for the Fotoman I wouldn't blame you! It is a beautiful, very well engineered, solid camera. The first time I saw and held one I **knew** I had to buy one!
We could look at alternatives for cones for you on teh Fotoman, but the closest I could come to the 75mm is the 90mm cone that I have for the Fotoman. If you wanted to swap out lenses, you can pick up a 90mm pretty easily for $300 to $500. The Rodenstock 90mm f/4.5 Green Stripe that I have is actually a pretty expensive and somehat big lens - it runs around $1,2000 used.
Although the Cambo is also a pretty decent 4x5 film camera in it's own right. I used the Cambo for the 47mm, 65mm, and 90mm lenses, and the Fotoman with a 125mm and a planned 150mm.
Cheers! Good luck!
