Samples: Steinheil Culminar 135mm F4.5

mount: M39 LTM, M42, Exacta
format: full format
year: ca. 1954-1960
max aperture: F4.5
min aperture: F32 (no clicks)
elements/group: 4/2
aperture blades: 16
min focus distance (mm): ca. 1200
filter diameter (mm): lens has no filter thread
length (mm): 129
weight (g): 369

additional information:
The Culminar's design goes probably back to the 1940s - more on Steinheil lenses you can find here and here. The lens has a couple of advantages, outstanding are: a very round aperture (due to 16 blades) and quite nice bokeh, relatively small MFD (ca. 120 cm) - and between 2m and infinity there is more than half a turn for focussing - the lens behaves at the infinity end as a macro lens behaves at close distance - you can turn and turn and the image still gets sharper and sharper. The head of the lens can be unscrewed and used with a bellows for macro exposures.






Thanks for looking!!

Edit - some links repaired!
