It all depends on the lens, Andrew. On 120 roll film, in 6x6 cm format, my 55mm Rodenstock Apo Grandagon (which covers 4x5) outperforms my dedicated 50mm Hassleblad Zeiss Distagon. My 110mm Schneider Super Symmar XL (covers 5x7) outperforms my dedicated 120 mm Hassleblad Zeiss Makro Planar. In addition, the superior performance of these two example LF lenses easily extends to the 6x12cm roll film format as well.Originally Posted by AndrewH
The main reason for using the Hassleblad (or my Hasslebladskys) is that they are much faster to set up and shoot (not really of a virtue to me - except for doing film testing).
