Not really…

Strapped the big Sigma on to my little Lumix 2x crop camera.

Tried to shoot the moon.

Focusing was truly abysmal. Gave that up as a very bad joke.

And now I think about it, I have at least twice the MP in the KP, and its 1.5-ish x crop sensor, so I could crop a bit more and end up with a better and bigger pic anyway, so there’s really no point in trying things like this. xP
