150mm f/4.8 Ilex-Calumet Series S (Acuton) - does it exist?

[Steve Goldstein]

I have a really nice 215mm f/4.8 in an Ilex 3 shutter and have also seen the later f/5.6 version in Copal 1. This family was also made as Acutons in 180mm and 150mm focal lengths, both f/4.8 and in Copal 1. Over the years I've seen precisely one of the 180s on the auction site, but never the 150. Has anyone ever seen one other than in the catalogs?

Just curious, too many idle brain cells today.

Yes, i have seen one 150/247mm f4.8 on the auction site and was lucky to get it for a very reasonable price.
It's a great lens, covers 5x7 i am thinking about getting a cone for this lens to fit my 6x17

Yes it does exist...I have one! It came with an Anniversary Speed. Copal shutter.

They were truly excellent plasmat type lenses and could be used as a single convertible. They were originally f4.8 but under different names many of them were made as f5.6.
