Considering switching from Canon to Nikon. Tried a D500 and found that I better BIF images than I did with my Canon 1Dx M2. Of course the Canon was tripod mounted while the D500 was hand held.
Going to give this a serious try, with lenses from 14-24 all the way to 180-400. Evaluation will include babies at a game a farm, Palouse and then Africa. Right now thinking of going with only Nikon equipment which makes me a bit nervous.
I'll be posting questions today to address some of my "concerns".
