Anyway. Few years ago I bought some Kodak printing lenses from a camera show. These lenses have odd focal lengths like 63mm and 93mm, etc. and they all have a fixed aperture. Like enlarging lenses, the front and rear elements can be unscrewed easily and if needed, a different aperture disc can be inserted to change the native aperture value. They came with brass tubes which are then mounted inside commercial printing machines. Yesterday, I finally found a way to mount the 63mm f4.5 Printing Ektar lens to the helicoid, and today I had a chance to take some pictures with it. The lens captures an amazing amount of detail. Just like the Schneider Componon 80mm f5.6 enlarging lens, this one also has limited use, but it feels great to be able to capture images with it, and with very good quality.
