The pictures here are uncropped
And some pictures in terrible light of distant Ruff and a Dunlin. Both pictures are uncropped but as you see I have magnified a selection of each picture.
So there is not much in it although the bazooka definitely under good conditions gives better quality pictures (see my recent pictures of the R-b Fly taken with the different cameras on different days) but with birds at some distance the superzoom often offers possibilities for a record shot that the bazooka may not have given.
The difference in size of the two cameras though makes the superzoom a much more birder friendly camera
