The cheapo effective 1,650 mm 5.6 tele (Q + adapter + Tamron 70-300 and other lenses)

Thanks for taking these shots.  I got my Q as a second body to take supertelephoto shots with my existing canon lenses.  I tried one pic with my Tamron 55-200mm at f5.6 and 200mm and it was horrible.  At first I thought it was the diffraction at 5.6 but after seeing your awesome 300mm pic, I think I must have just misfocused or shook the camera when I pressed the shutter.  Anyway I can't wait to try again!
