Primary, I apologize for my bad English. Then, I need help for a question about architectural photography with digital sensors.
I have not yet found a digital alternative to architectural photography in large format.
I know the cameras such as Sinar P3 or Silvestri S5 Micron, and Sinar Artec or Arca-Swiss R-series too, but the real problem is represented by lenses.
Lenses designed for large format photography cannot be used on a digital sensor, not only because they are too "long", but also because their resolving power is not enough for the digital sensor .
Digital Schneider and Rodenstock have focal lengths good for architecture, but also have a poor image circle, that often barely covers the medium format sensor.
So you cannot use camera movements: tilt, shift, swing, rise or fall.
The sensor I use ( Phase One P45 +) has a diagonal of 61.36 mm.
Here are the lenses that I can use:
Rodenstock Apo Sironar Digital 4.5/35mm - Image Circle: 105mm
Rodenstock HR Digaron W 4/40mm - Image Circle: 90mm
Schneider Apo Digitar XL 5.6/35mm - Image Circle: 90mm
Rodenstock HR Digaron 4/35mm - Image Circle: 70mm
Rodenstock HR Digaron 5.6/23mm - Image Circle: 70mm
All others have an image circle smaller than the diagonal of the sensor.
So I wonder: why using a Sinar P3 when I cannot have a lens that respond to the capability of the camera?
Where am I wrong?
Thank you very much.
I wish a fantastic 2014!
