My father recently gave me a nearly 50 year old camera, a Konica Autoflex T (full 35mm). When I inspected the lens, a 52mm 1.8 prime, it had a UV filter on it, but once removed, I could see it was in pristine condition.I was curious to see how it would do on my Sony A7iii, so I found a 3D printable file online for Konica AR to Sony E and a half hour later I was shooting (with manual focus of course). I decided to do some side by side shots with a Canon 50 1.5 adapted over with a Metabones Adapter and was very happy with the results. For the cost, its pretty awesome! Enjoy!
