Miniature Petzval lens
Miniature French Petzval, 2 inch focus, late 1850s, early 1860s. Some refer to these as apprentice pieces or exhibition pieces, the real origin is not recorded. I have handled four of these and know of another three, I doubt if more than 20 were ever made. The lens is a perfect miniature, the glass being just under 1/2 inch diameter giving exceptional results on my Olympus E-P1
