I also switched to digital a couple of weeks ago and have been feeling something similar... I converted a lens from a cheap film p&s I like but it's way too shit on a digital sensor.
That lens you got looks nice, good shots with it
Yea I think if you can manage to find a focus point then it has an acceptable resolution. Certainly not an easy lens to exploit the best, but easy enough to use like a disposable camera.
