Carl Zeiss Jena Sonnar Electric 135mm f/3.5 – 5th Generation – 4 Digit Serial Number + JML 20X

One thing I didn’t know about this lens before receiving it was the fact that it incorporated an in-built lens hood that slides out, much like the Nikon 35-70mm f/2.8 AF-D Macro-Nikkor from the 90s. This is a handy feature as microscope lenses are very prone to glare from any light seeping into their immediate vicinity. To mount the JML 20X shown you’ll need this 49mm adapter.
