First day with the Panasonic Leica 100-400...C&C PLEASE!

All of these pics were tweaked in Lightroom, but there were no adjustments to increase sharpness.  There was a lot of wind, so I used the monopod and it helped.  I'm very happy with the lens so far, just two issues (I'm not a pro photographer, so I can't provide any kind of technical analysis)...it  IS heavy and a bit difficult for me to hand-hold, especially in the wind today, so I used a monopod.  The zoom ring is pretty stiff compared to my 20-150 Zuiko Pro, but I think it will loosen up in time.

Not cropped.

Not cropped and no monopod.

Very slight crop.

I would really appreciate comments and suggestions!
