Even though the K500 is a relatively simple design, it's possible that
the lens took enough of a bang in the past to make it less sharp, I say
this because even cheap 500mm long lenses from that era were acceptably
sharp when stopped down a stop or two.

1) Is the lens really dirty of just soft? Put it on a tripod and

(I might even try flask.) Can you get good results, or is it just
your technique?
Honestly, it's probably just soft. I've done lots of tripod shooting
with it, and it doesn't even start to look sharp until f11, and even
then I have to add a ton of sharpening in Photoshop to make the images
look halfway decent. I just thought, well, *maybe* the glass just
needs a cleaning. It is an old lens, after all, and was in some guy's
closet for more than a decade before it came to me.
You could get it cleaned, but you'll still end up with a big/heavy lens.
That's a good point.
