Re: Seitz Roundshot 220VR lenses

[Gene Woolridge <gene360@xxxxxxxxx>]

When I was looking at the 220VR, I tested the camera with a 28 Nikkor-PC and it
worked really well. Covered top & bottom too! As Michael stated I wanted to cover
the whole neg height and opted for a shifting adapter that I had HULCHER build for
me a year before Sietz had the Hass. shift on paper. All is working well & making
beautiful prints with it! If needed for QTVR, don't shift the lens, but you would
still
have full frame top to bottom.
