You certainly were active today. Good exposure on the flight shot despite the bright sky and good panning for the kingfisher considering they fly so fast and low thereby offering little reaction time. All this with a heavy lens. I sure could have used your 600mm's reach for the GCFC today, although at f6.3 I may not have captured enough light with only first-generation stabilization. I wonder how profound the IBIS is for the new Canon R cameras? I mean, I know what they purportedly achieve but I don't really know how it feels when using it in the field. It must be amazing. I heard that there was a Sora at Sam Smith. I don't suppose that you saw it. That may have been a few weeks ago ... I lose all track of time. There was one at Reesor pond (south) ... the little pond in Scarborough, not the one in Markham.
