Really? 1/50th at 800mm?? Really? One has to shoot with 800mm lenses to truly understand how remarkable it is to have a sharp image at 1/50th sec at 800mm handheld.
Show off!! Remarkable.
My R5 is ordered, but I have no idea when it will show up yet. My only 800mm long is a bit heavier, a Sigma 300-800 from about 2005 vintage or so. Almost always shot from a tripod with a Wimberly head. Not hand held, for sure.
Was this shot late in the day or in the shade in a very overcast day perhaps?
