yes. I bought a Medalist and converted it to 120 roll film. Hard to handle but the Ektar lens is worth the bother/.. Ed
BTW, this lens is virtually identical to the 105mm, f/3.7 Ektar sold by Kodak for use on small press cameras. The speed difference is due to the maximum aperture limit of the Supermatic shutter it was sold in. This is a Heliar type lens built according to the Altman patent. Altman wrote that he used the extra element to help correct "rim-rays" to reduce the aberration of the lens at maximum aperture. Other lenses in this series include the 50mm and 75mm Kodak Enlarging Ektar and some others. Altman appears to be one of very few designers outside of Voigtlander to exploit the Heliar type.
