Thanks very much. The in-focus field
diameter projected by the transfer lens
is exactly 50mm which is what it ought
to be. The flat (corrected) part of the
image is about 38 mm across. The smaller
sensor of the *ist D has certain
advantages here; the field is flat to
less than 0.5 mu all the way across. And
so -- as long as the sensor is normal to
the beam we have a perfect match. I have
noticed, since starting to use the *ist
D, that the images are far sharper in
the corners than I generally got with
film, even when using Plan Apo and Plan
Fluorite objectives and the Wild camera.

Hi all,
Does anyone know the exact distance
between the front surface of the *ist D
mount and the sensor?
