A Cirkut camera #10 is being sold at Ebay now. I am thinking of buying it. But I have no idea how it works. Could you help by informing the followings? 1. Can I put modern lenses on it? If yes, I can use different focal lenses to take pictures. 2. Is camera movement available? It is important to have perspective control. 3. I know it can take 360 degree photo. Can I take just 150, 180 or 270 degree photos? 4. Can I use 9.5" aerial film with #10 camera? 5. Some people said it could be difficult to get perfect exposed picture with Cirkut camera. Or it may require 2 to 3 exposures to get one perfect photo. Is it true?
