Is this Sinar lens in fact a Apo-Sironar-N?

jah3 · Dec 19, 2014

I have one Sinar named lens, Sinaron S 72° 1:5,6 f=150mm MC with a serial of 11147XXX and i was thinking it was a Sironar-N, but then i read these in fact would be Apo-Sironar-N lenses.
It takes a 49mm filter and is quite small.
Made by Rodenstock Germany.
Can someone help me with this?

Yes, you are correct, APO Sironar N.

I found that post, but got a note from someone shooting LF that it would not be the APO version? IS there any other sources available? I have only found varoius forum postings with mostly "maybes".

The Sironar-N and Apo-Sironar-N are optically the same lens, just the labeling is different. So functionally it makes no difference. Your serial number is from the early '90s, around the time when Rodenstock was transitioning from the "Sironar-N" labeling to the "Apo-Sironar-N" labeling.
