I shot this video with the R5 and RF100-500 with RF1.4 extender. Shot in 4K crop mode. I have been playing with video a little the last year. If the video does not play I will delete this post.
A pair of Peregrine Falcons nest under the Mississippi River bridge at Hannibal, MO. I have been watching them off and on since late 2018. This is one from a spot I just discovered it likes in the last year that is not conducive to shoot at. (Shoulder of very busy road) So handheld from drivers seat out passenger window. I was very pleased to get, to date, my best video so far.
Just returned from the ME with the 100-500 accompanied +-1.4x TC, in blazing heat (103+ deg F). I was fighting heat shimmers all of the time and as a result many images were unusable (no fault of the lens/camera). Here are a couple Nubian Ibex with papa and one of the newer kids captured with the 100-500.
