I am thinking of buying a 7x17 camera, and I would like suggestions regarding wh ich one to buy. The three available are from Wisner, Canham, and Lotus. I am kno w Wisner's cameras well, but I have heard mixed feelings regarding Canham and ne arly nothing about Lotus. I have heard that the Canham is shaky, does not lock d own well, has screws that come loose, and has a bellows that tends to rip off th e standards. I have also heard that it is very well made with great attention to detail. Any comments from Canham, Lotus, or ULF Wisner users? Which 7x17 should I buy?
