Dunnocks in Full Song

We took Phil's new lens for a trip to Wicken Fen this afternoon. This Dunnock was singing repeatedly from a ground level perch - in contrast to the one taken on the Exe Estuary that inconveniently sang from a skyline twig. As the lighting conditions were very different it is quite difficult to compare Phil's 400 mm prime (first two images) with my 100-400mm zoom. More tests to follow - or perhaps not as it is not always wise to compare lenses - just enjoy the moment.
