I'm shooting for fun, using a Pentax film SLR.
how much difference would I notice if I were to buy a (relatively) modern K-mount prime lens, compared to my ancient SMC M 50mm 1.7?
I'm trying to decide whether it's worth upgrading or not. Ken Rockwell calls my current lens 'excellent'.
I also want to buy a wide angle lens but I can't decide which one.
