Lens info wanted

[olroy2044]

I found this lens in my drawer. I had forgotten about having it. It is the first "wide" lens I bought way back in 1967 or so. I think it came from Cambridge's ad in the back of one of the photo mags of the time. It is a D.O. Industries Auto 35mm f2.8. Solid, all metal construction, good build quality and decent results. From what I have been able to find out, the company is still in business under the name "Navitron," building projection lenses and possibly some military applications.

Does anyone know anything about it?





ISO 200 f/11 touch of unsharp--no color tweaking at all Composition stinks, but the lens did its part!


This lens is going to get used!

It appears to be a Chinon Japanese sourced lens, many suppliers put their own names on generic source lenses. Even Vivitar is only a brand, not a maker. There were about six actual manufacturers of optical lenses in Japan in the 1960's/70's, and they all made other "named" lenses, even making for German distributors like Porst etc.
Most of these lens are good, after all, by the 1970's the Japanese had 50 years of making lenses by then as experience, and unless cost paring reduced the quality by cutting corners, they usually work quite well.
