I recently purchased an Ektar 152mm f4.5 in a supermatic shutter on ebay. I did some research, and it seemed like a good deal at $99.00. But I would like to get opinions from the group on this lens. The serial number indicates that it was made in 1947. I plan to use it with 4x5 for landscapes. Probably on a Crown Graphic, and maybe on my Zone VI field.
