The Series IV Professional Edition incorporates our brand new
high resolution 'Black Chrome' ronchi screen. This is a 300 line/inch
black chromium ronchi grating etched on optical glass. It was
manufactured on the same machines used to etch integrated circuits.
The screen itself is calibrated to within .001mm of the factory spec
for your camera. The result is that even CCD users working with
f/3.3 focal reducers will be put in perfect focus in only seconds!
Series IV Standard and Pro Edition models are available for nearly
all 35mm, CCD, and Medium Format cameras. Using our modular approach,
you can go from one format to another on the fly, or easily upgrade
when you move to a different camera model or brand. During the special
introduction, shipping is on us!
