This kind of surprised me - a review of a 40 year old lens on the K1. Spoiler alert - it does quite well.
I sold my 135 f3.5 some years ago, and I'm not sure that I'd want to fiddle with a screw mount adapter on the K1, but this review does bring back memories of those finely tooled lenses that were a joy to use.
