I have a few Promaster lens, were sold as kit lens with Minolta, Pentax, Nikon and Canon bodies, were either Tamron or Sigma. I have not seen Pro Master paper in my market for a very long long, the store that I bought it from is no longer in business, the owner was certain it was Mitsubishi which he said had or has has a coating plant here in the U.S that makes inkjet paper as well. At the time he sold to schools and college students. The paper I used was pretty good, quality seemed fine, responded to filters just as ILford. If my local store carried it I would buy again.
