History: A very intriguing lens that packs a heavy punch. The Plasmat was a small revolution back in its days. It offered not only a very nice and corrected field, but also a quite fast open aperture (F4). Furthermore the symmetrical layout made it possible to use each cell of the lens at a slower speed (F8) to cover double the image area, making it one of the most desireable lens layouts on the market. The only drawback beeing its hefty manufacturing costs, since it is a 6 elements in 2 groups layout.

Condition: The condition of this specimen is very nice. The aperture mooves smoothly forth and back and have all its leaves. The glass is in an good condition, some cleaning and minimal dust specs, but this will not affect the image quality. There is no fungus, haze or any chips there.

The compound shutter is working so far as i can see. Only the slower times sound to fast to my ear, so no guarantee there.

The lens offers a combined focal lenght of 240mm and will work best for 5x7 and fullplate formats. Also each cell on its own (front and back) used alone will offer a focal lenght of 400mm at F8, useable for up to 8x10 and 11x14 formats.


The lens comes with a fitting flange.
