Kowa makes great optics. Back in the day I had a small commercial dark room and a couple of Kowa Six cameras I used to catalog art work for some noted wildlife artists. I used a pair of Beseler 23C color head enlargers and printed 8X10s from transparencies onto Cibachrome paper, a positive-to-positive process. Cibachrom was great for true colors and saturation, and it had a stable archival quality.
I had been using a borrowed Bronica camera, then bought the Kowas. They were easily on par with the Bronica, high praise.
Buy a Kowa with confidence.
