Hi Edurado,
ONLY the Rodenstock Digital HR 28mm & 35mm have an image circle of 70mm (stopped down 2 f-stops at Infinity).
The HR 60mm, 100mm, and 180mm have a bigger circle of 80mm.
The 28mm and the 35mm, although given only with a 4mm, respectively a 6mm shift range, can be shifted more, without any noticeable vignetting up to 10mm: the values given are pretty "conservative" and on the safe side.
Member "rehnniar" as made some interesting comparison tests with the Rodenstock 28mm, 35mm, 60mm, ... and I think he had made them available for anybody asking.
And FYI: a Sinarback can also be mounted vertically on a V camera.
Hope this helps.
Best regards,
Thierry
I found out that the popular HR digital lenses have only 70mm at f8 (optimal aperture). These lenses only allows 6mm of shift with the very popular 37X49mm digital sensors.
According to my book, 6mm shifts in this format for archicture photography is not enough. Even for product is very limited. Canon TS lenses have 11mm of shift either way. Well, 9mm to be safe.
Why such a small coverage?. I know they are optimized for smaller digital sensorr sizes, but 70mm circles only? - Come on!
Can someone tell me here if Phase One P25 back can be mounted vertically on a V camera? I've seen here a picture of a Leaf back that can be mounted both ways.
Thanks
Eduardo
