  Table Of Contents ✓ Lens Version The lens can be divided into two different major versions: Version 1: Wide white bands and narrowly banded black bands on the aperture and focus ring. Serial Number <4,000,000. Version 2: Narrow black and white bands on the aperture and focus ring. It is also available in Enna "Sockel" mount. Serial Number >=4,000,000. Tele or not tele? For photography lenses, a telephoto lens has a focal length larger than the Total Track Length (TTL), where TTL is the distance from the surface of the sensor to the top of the lens. Enna adds “tele” before the name Ennalyt to indicate a telephoto lens. For example, Enna Tele-Ennalyt 90mm f/2.8(Ernostar design) is a telephoto lens while the Ennalyt 95mm f/2.8 & 100mm f/2.8(Triplet design) is a long-focus lens. Photo taken by Dr. Klaus D.

Rodenstock Lenses Serial Numbers for 35mm Interchangeable lens cameras (羅敦司得可換鏡頭序列號)

Rodenstock was a well-known manufacturer of medium/large format lenses as well as enlarging lenses. From 1950s to early 1960s, they had produced some interchangeable Lenses for 35mm SLR and viewfinder cameras. Like many other Germany manufacturer, the lenses changed from chrome finish to black finish with focus/aperture ring in zebra style. Although Rodenstock produced two million lenses from 1954 to 1961, it seems the production number of interchangeable lenses is relatively low compare to other Germany manufacturer.  I have included some data on serial numbers in the list below. As I don’t have the official production figures, the data may be far from complete.

If you found any errors, please let me know too. Below is the list of all the interchangeable lenses made for 35mm cameras, sort...
