Hi Folks,
I have just come across a lens and am wondering if anyone would know anything about it.
According to the stamping on the housing its a Bausch & Lomb. Stamped on the front element holder it is stamped 18 In EF. With my rudimentary knowledge of lenses, I am assuming that it is a Petzval, as there are simply one element at the front and another element at the rear.
Can anyone tell me anything about this lens? Can anyone tell me what kind of coverage I would expect? I am hoping to get at least full plate coverage.
Also, how do I calculate the aperture and check the focal length of this lens?
Cheers
PS - sorry about the name in the title. I know its supposed to be Bausch!
