To each their own, but I find swapping lenses quickly with a screwmount adapter (esp. from screw to nonscrew) really cumbersome. I'd buy a 50 1.4 SMC tak if I found one for a good price, but I really value ease of use. I'm one of those guys who would pay a lot more for the A version of a lens. I hate stop-down metering my K55. It's worth it, for now, but I generally think that the first manual prime someone buys should be a little easier to use than M42.... especially if the lens does not expose properly (like all non-A lenses do on my k20d)...
YMMV, but if I am shooting a moving target, I only want to worry about focus, not focus, stop down aperture, and exposure errors...
