IMHO
The rank of Pentax 35's is FA35/2>K35/3.5 >> K35/2>M35/2.
Keep the K35. They don't make anything like this any more and nothing does colors the same.
K55/1.8 is a tricky lens to rate. Below (Wider than) f/8 mine is soft, but it competes with any 50 I own at and above f/8 for sharpness. I've had at one time or another almost everything but the A50/1.2. It has some kind of mild 3D effect I haven't seen in another lens (I read the FA31 is the queen of this), and it sells for so little money neither keeping it nor selling it matters. Maybe
give it to a young K-mount user.
FA50/1.7 really doesn't bring anything special to the table against your other lenses.
