€1100.00 EUR

Shipping costs will be calculated at checkout.

History: The lens is engraved with: 'A. J. Thompson & Co - Importers - Boston'. Thompson was an US importer for optical and other technical equipment. He had a contract with Darlot, from whom he imported the lenses. This quite early lens is probably around 1860ies, since it lacks a waterhouse slot and also the screws on the rack & pinion mechanism are really large (which was a sign for early lenses).

The focal lenght is about 300mm (or 10") and the open aperture is around F4. It will work best for 8x10 format with a destinctive petzval character in the outer region.


Condition: This brass beauty comes in a great condition. The brass looks nice and shows a fantastic patina. The rack & pinion mechanism is complete and still works perfectly. The glass is in good condition, there are only very few cleaning marks, which is rather unusuall for such an old lens. There is no haze, fungus or anything that would affect the image quality.


It comes with a flange and even the original leather lenscap!
