P3D vignetting tests

Sure.

A couple of weeks ago, I shot some test photos with a Kodak and two 3.5
Realists.  I shot all three cameras at the four smallest apertures.  At the
time I was interested in focus.  I have that film in my hand now.  (Why the
film is next to the bed, I don't know.)

Anyhow, it's unmistakable.  The two Realists show vignetting in the bright
part above the horizon.  There is vignetting on both Realists at both f16
and f22.

The Kodak shows no vignetting.  And I might add, I couldn't find any
difference in the three cameras, sharpness-wise, and I used both a loupe
and microscope.

(I'd like to mention that one of the Realists belongs to George Themelis,
who generously lent it to me for testing.  Thanks, George.  It's nice.)

Anyhow, in side-by-side tests, the two Realists showed vignetting at the
smallest apertures, and the Kodak showed none.  Just my little experiment,
your mileage may vary.
