16.5cm Carl Zeiss Jena Tessar for 8x10

[Steve Williams_812]

I am looking at a 16.5cm Carl Zeiss Jena Tessar for use on 8x10. It is in an Il ex #4 Acme shutter. Can anyone tell me the image circle on this lens?

According to more knowledgeable sources on the web, a tessar will cover about 60 degrees - this works out to a 190mm image circle  way short for 8x10 at infinity. Is someone out there marketing their tessar as a 8x10 lens??

To cover 8x10 at this focal length, youll need a 165m Super Angulon (ouch  expensive), or one of the more moderately priced older lenses like the 159mm Wollensak Extreme Wide Angle.

The 165 (non-super) Angulon will also cover with some room for movements stopped down. Some of the later ones are coated and in reasonably modern shutters.
