Berthiot Olor IIa n°8 - 300mm f5.7

A slower berthiot lens that covers more than 60°. The catalog asserts that it is sharpest wide open and that the only reason to stop down is to increase depth of field. It adds that f/5.7 Olors shorter than 255 mm are so well corrected that they can be used for reproduction and trichromie.

It will be a perfect daily lens for 8x10 shooters as for tack sharp portrait than for landscape and outdoors works.

Glasses shows minor cleaning marks. Aperture works smoothly.
