Derogy Convertible Petzval 140mm F3.6
This very early Petzval layout lens comes from one of the most
exclusive french lens making workshops: Derogy Paris. This lens was introduced in 1858 and called: Objectif a foyers multiples et lentilles addictionelles. It features the portrait petzval layout, but it also offers more options, like the additional glass element which changes the focal lenght. For easier use it also features the Derogy bayonet system, which greatly improved the changing the inner elements.
Condition: The condition is very good here, i would say it makes a fine specimen in any collection or any shooters cabinet. The brass is authentic and unpolished, while the glass is mostly clear, showing some only minor cleaning marks and specs here and there.
lens has a focal lenght of 140mm at a speed of F3.6. It will work best for 4x5 formats with fine petzval characteristic on the ground glass.
Lens comes with a flange (not original but holds the lens well), a washer stop and a middle glass element.
