early Bertaud Portrait Petzval 300mm F3.8
History: A very interesting Portrait petzval for the 8x10
format. As with many early french lenses it doesnt feature an engravong on the barrel, but its market on the glass with 'B J' on one side and also 'Bertaud J - 1854' on the other. Imagine, this beauty was made 166 years ago!
Bertaud was a young and very talented Opticien who made lenses in the very begining of the wet plate era (from 1848 - 1867). It is mentioned that the optical quality was outstanding and in 1851 he participated in the great Exhibition in London!
Condition: the lens is in very nice and authentic condition. The brass of the lens comes with an authentic and warm patina, showing only minimal wear. The rack & pinion is comple and working. The lens was made before the waterhouse era, so it doesnt feature a waterhouse slot. The glass is in really really good condition, it shows only very light cleaning marks, but overall it is very clear and doesnt show any signs of seperation, haze or fungus. All in all i tested this baby on the ground glass and the image was very nice with a very sharp center.
has about 300mm focal lenght (12") and an open aperture of
F3.8. It will cover 5x7 and 8x10 format with a nice petzval character especially at portrait distance.
Lens comes with a fitting flange.
