It's not about the tool, its how you use it

My Q is in the mail! 

But you'll need a good fast lens, because diffraction is already lurking at f/2.8, obvious at f/4, and a killer at f/5.6... (Correct me if i'm wrong, i haven't tried it for myself yet).

That said, i've seen better pictures of the moon with the Q+DA*300, than mine are with the K5+Sigma APO 400 f/5.6 and Sigma 2x TC

Here is mine, for the record.
