History: The Cone Centralisateur lens design (which is a petzval design with a larger back element to avoid reflections), is absolutely famous and sought after in the late 19th century and even more today. It was the flagship lens for Jamins workshop in the early 1850ies and 1860ies in Paris. It offered better optical quality then most of his rivals, but also a possibility to it as a portrait (portrait mode) lens and also as a landscape lens (paysage). Even though its a a petzval design, you will see a slight difference to other portrait petzvals from that time. The Cone Centralisateur lenses have this cenrtain 'something' to their image, which is hard to grasp, but many people are looking for.

The engraving reads:

'ANCne Mon JAMIN - DARLOT, Sr OPTn Bte - 14, r. Chapon Paris'

This dates the lens back into the years between 1862 and 1864, after Darlot took over Jamins workshop. After 1864 Darlot changed the engraving showing his name only.

Condition: This beauty comes in a great condition! The brass shows only light wear and still a warm patina, the rack & pinion mechanism seems complete. The glass is in great condition too, there are light cleaning marks here and there but nothing that would impact the image quality at all.

A great bonus here is that the lens comes with the inner washer style stop part. Which can be used to stop down the lens to aprox. F6.

With its fast open aperture of F4 and a focal lengh of 220mm (or almost 8 1/2"), this lens will work anywhere from 5x7 and fullplate formats.


In landscape mode it will have an estimated focal lenght of 500mm, covering huge ULF formats like 14" x 17" !

It comes with a fitting flange, washer stop.
