Large format and IQ180

[NN109526UL2]

I want to shoot large format with my IQ180 back. What are the lens lengths needed to compare with the standard 4x5 film lengths? I want APO's if possible. ie: the 4x5 90mm, 150mm and 210mm lens lengths would be what for the 180 back? Also, is the flexadapter the best way to focus precisely before sliding the 180 over the viewing screen and taking the shot? I have a pristine Cambo SCX system so I would like to just change my glass to APO's or the sharpest possible. I don't care for the zone focus of the Alpas. How wide can it go before the colors change too much to make it worth while? This will be used for products, architecturals, vehicles, food, artworks and scenics. Thanks a lot.

I am answering my own questions. Digital Transitions has a nice chart for the lenses that should work with my Cambo platform. They are a very good source of information. My Cambo is solid, so I won't make a switch to the Arca platform, at this time. I'll just shorten the main rail a bit. I'll keep the S/T movements. Due to the extreme angles of light coming out of the 35mm lenses, I'll start with the 50, 60, 90 and 150 APO lenses, from Rodenstock or Schneider, with manual Copal shutters. I am intrigued with the longer, 240, 300 and 400 APO lenses. I'd really like to see an image from them, using the IQ180 Back and a solid 4x5 platform. There are few published resources for this working platform, so I'll just open a Vimeo and YouTube channel and see what happens as I experiment and run the jobs. Always fun. Anyone have a link to a long-lens (240, 300 or 400mm), IQ180 Back image?
