History: The Cone Centralisateur lens design (which is a petzval design with a larger back element and a cone shaped rear part 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 normal 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:

'JAMIN & DARLOT Btes - R Chapon 14 Paris - 3403'

That engraving puts the lens in the short time period of early 1860 where Darlot became the partner of Jamin. Just a couple of years later (around 1863) Darlot took the workshop over.

Condition: This brass beauty comes in a great condition! The brass shows some wear and still an authentic patina, the rack & pinion mechanism seems complete but not really working. The lens features a washer stop option inside (no stops included). The glass is in nice condition too, there are a few cleaning streaks here and there,  and a small chip in the edge of the rear lens, which wont affect the image at all.

With its fast open aperture of F4.5 and a focal lengh of 330mm (or almost 13"), this lens will work anywhere from 5x7 to 8x10 format (and very likely even 10x12 if you really want to see alot of petzval character in your images and some light vignietting).

In landscape mode it will have an estimated focal lenght of 600mm, covering huge ULF formats like 20" x 20" !

The best part about this lens is, it comes complete with the authentic flange and also the brass lenscap.
