Rodenstock Sironar 150mm f-5.6 in Copal 0 Shutter

Does any one use this lens or has used it and could give me some pointers as its good side or bad side! I have a 4x5 I am hope-ing to use it on it:
I was advised it a Pre-N series Lens???:confused:

I've been using one for over 20 years and they are superb lenses, mine's an N series. The differences between the series reflect the minor improvements in design and glass technology over the decades.

They are comparable in quality to the Symmars. What is more important is whether the lens is single or multi coated. If it's a reasonable price go for it.
