I bought the lens and here's how I cleaned it:
Water spots behind the front element. Mousey says hi.
This is a delicate operation so you need the right tools.
Stuff your knife under the plastic ring and pry gently.
Now you have to unscrew the three small screws that hold the front element to the lens. Eyeglass screwdrivers are perfect, but I'm awesome so I used pliers.
The front element will detach, leaving it open for cleaning and the front portion of the internal second element. Note that the plastic ring with the screws will also detach from the front element, even though in the picture it is still attached. So don't hold the two together by just the plastic ring, because the front element may detach and drop into dog poo.
When putting the thing back together, do not overtighten the screws because Tamron is awesome and made the screw threads on the body out of really easily strip-able plastic. Go Tamron.
I focused on the word "Tours" in this shot. So it backfocuses a little. Nothing that the in-camera focus compensation on the D300s won't cure. This was shot wide open. Pretty sharp at 50mm.
This was 17mm wide open. Edges are crappy.
And this is 17mm at f/8. Edges much better.
I am going to go eat bacon now.
