The store I work in is selling this Graphic Kowa 270mm f/9 lens on the eBay store. It was on an Argyle 12x24 copy camera. Theres just one problem, my employer had asked me to find out of the lens is apochromatic or not since it would seem that appears to be an important feature for some people considering the lens. But I've searched google, as well as kowa.com (Which seems to be Medical and Scopes), and I cannot figure out if this lens is Apochromatic or specifically color corrected for say copy work as I cannot find any specifications of it online other than it's focal length and max aperture.
Was not sure as some of our older copy lens and such were, but never had them listed on them, and have had lens in the past that had almost nothing on them, but did contain desirable characteristics only said in say a specification guide.
Whoever bought the lens (Sorry I didn't catch your Apug Name on the phone), I'd be curious to know how you like it when you get it on your 7x17, message me sometimes.
