Double Protar Series VIIa Wide Field 8X10 in Compound
Here's a fine choice for wide field use on your 8X10 camera.
The Protar Series VII was Zeiss answer to the Goerz Dagor. But the Protar was 4 elements in a group not 3 like the Dagor. As a result it was far better corrected for single element use, making it a true convertible lens.
So this lens has two 16 1/8" (410 mm) f12.5 cells that when combined make a 9 1/4" (235 mm) f6.3 lens that covers the 8X10 format with moderate movements. I've used one on the Deardorff with as much front rise as the bellows would allow and not seen the edge.
If you remove the front element and use the rear group by itself, you have a 410mm f12.5 lens. Both aperture scales are on the shutter. The shutter has been serviced and is running perfectly.
Common for these to have the yellow balsam showing at the edges. It looks nasty but really doesn't hinder performance. Gone by f8. Overall this is in wonderful shape, with glass surface flawless. Original flange is present. It'll be a fine performer for some lucky buyer. $415.00 shipped in USA
