The lens has a focal length of 350 mm with an aperture of 11. The wide image circle capabilities of 350 mm makes it possible to use the lens up to a format of 8 x 10 inches or 18 cm x 24 cm. Even when fully open, the apochromatically corrected lens, fully symmetrical with four lenses, exhibits excellent reproduction performance and has a homogeneous resolution with a very high contrast at a working aperture of 16 or 22.
Baseboard cameras with short bellows extensions of up to approx. 320 mm can use an accessory lens tube, which shortens the distance between the lens and the camera by approx. 44 mm without mechanical vignetting resulting in a distance between the lens and camera of 280 mm. The back of the tube has a size 3 thread so that conventional lens plates with a size 3 inner diameter can be used.
