Thanks for the correction, Lou.
Thanks for the correction, Lou.
Mr. Shiu is correct- you remove the front group of the 150mm Symmar to make it a 265mm lens. Opinions vary on the optical quality of the rear element alone, but you'll soon find out for yourself. Looks like you have good find!

What I recall about the Symmar is that when you use the rear group alone, it's an appealing soft focus look when not stopped down much.
I think that is a Prontor shutter. It looks like the Prontor logo on the right front, photo 4. Has anyone seen a dial-set Prontor? The lens serial number indicates circa 1961-62. The 1962 Symmar brochure on cameraeccentric shows the 150 mm Symmar came in a no. 1 shutter but doesn't list what shutter choices (if any) were available.
I was surprised to see the 150 mm Symmar came in a no. 1 shutter; I would have guessed no. 0. Looking a bit further I see the 150 mm Symmar-S came in a no. 0 shutter.
On edit: Googling this turned up an image of a dial-set Prontor with a Dallmeyer oscilloscope lens.
Does anyone know when the plasmat formula Symmar was introduced?

The first Schneider Symmars were f/6.8 designs; similar to a Dagor, I believe. Those were replaced by the "convertible" Symmars (as seen here) in the mid-1950s. I've used several of those lenses over the years; all of them were in Compur shutters. That lens series was replaced by the Symmar-S line in about 1972. I once had the introductory brochure for the Symmar-S lenses (long gone) where Schneider mentioned eliminating the convertible feature in order to improve optical performance. I've used both convertible Symmars and Symmar-S lenses and they are fine performers... never had a chance to do an A-B comparison, though.
Thanks Oren, that's the one. When I got hired at Kodak in 1984 the English version of that brochure (along with a bunch of other ephemera) was in the desk they gave me. I still have some of those papers...
