Berthiot Perigraphe 135mm f14 - 3bis - wide angle lens for 8x10

A pretty rare early berthiot wide angle lens. This 135mm covers easily 8x10 and closed down up to 10x12. Don’t often seen on the market

With flange and original cap. Lensboard not include

“wide angle anastigmatic périgraphe covers a considerable angle; at small apertures, the diameter of the circle of good image quality exceeds twice the focal length; the angle covered is almost 106°. The two lens groups that make up this objective are symmetrical; they can be used individually and are then good simple [the French call lenses that have one group, such as either cell of a Dagor, Eurygraphe or Perigraphe, simple] lenses. The focal lengths have been chosen in such a way that the angle well covered on the longer side of the plate exceeds 90° at apertures from f/30 to f/40; it exceeds 96° at f/50 to f/70 when the lens is used to photograph interiors or near subjects. By combining two lenses [individual groups] of different focal lengths, one can make asymmetrical périgraphes, letting us make wide angle casket sets giving combinations whose focal lengths are approximately a quarter of the sum of the two components’ focal lengths.”

Please note you’re buying 100 to 150 years old items. Patina, scratches on barell etc. are signs of their previous lifes. I try to be as precise as possible so feel free to ask more picture (daylight pictures for example) via messenger or mail
