D7200, 500f4 + 1.4 TC, ISO 800, 1/2500s @ f/5.6 (not sure about the fstop but that's what the EXIF says; lucky the birds were all pretty parallel to the plane.)
Pretty sweet to get four ducks to coordinate this well! Nice HAs throughout and I like the hint of pink clouds along the bottom of the frame. I'm okay with the crop but could also see it shifted up a bit more as well. A image for this months theme in particular. TFS
