Thanks, Click! It’s been fun getting these images. I’ve watche the family gather steam to cross the river, feed, then cross back, and find a spot to sleep, but I haven't actually seen any adult Mergansers in the air. Hopefully I’ll get some airborne images some day.Very nice pictures. I especially like the second one. Well done.
...there is so much to unpack in your wonderful posts in this thread and here.I thought I'd give the RF 800mm f/11 a whirl on the R6 because it should give the same resolution as the RF 100-500mm on the R5 and the large pixels on the the R6 would not be affected so much by the f/11 diffraction. I thought the high iso performance would be good, but I was bowled over. I was set up for BIF at 1/3200s and suddenly a small bird dropped by for a second, some 15m away in the shade. This is an 800x800 pixel crop from the centre at iso 20,000 of a Whitethroat.
