I do believe that they did stretch it a little bit, but it
really is true. However, in the case of the 4/3 sensor, the
amount of it is very limited. A full-frame 35mm definitely
would be problematic if, say, the sensor used in the E-1 were
FF, 35mm.
I'm using a lens that pushes the limits of off-axis light
pathing. The Zuiko 35/shift which is being loaned to me by
Joel. (I think he wants me to buy it back). Anyway, the
results are absolutely amazing--however, you have to work for
them. When the lens is used with minimal shift, the image is
sharp and uniform edge-to-edge. When used at maximum shift, the
fall-off is noticable and the chromatic aberations start to show
up. The severity is overstated, though. A five-frame stitched
panaramic (ultra-easy to stitch), gives me around a 16MP image.
The fall-off and edge distortion is very similar to what we see
of wide-angle lenses on the 5D or the 1DS cameras. Really, in
the case of a maximum shifted image, only about 1/3 of the image
would be considered to be "marginal".
