I found some problems with the new D500 AF. I tried test several Nikon lenses using both this method, https://nikoneurope-en.custhelp.com/app/answers/detail/a_id/51633/~/how-to-use-the-af-fine-tune-function and the on-board method, http://nps.nikonimaging.com/technical_solutions/d5_tips/af/auto_af_fine-tuning/. Consistently, only the 16-85mm AF-S needs no adjustment. Some older ones, 50mm/f1.8, 35mm/f2D, 80-200/f2.8D, all need to adjust to about "-10". These lenses all focus dead-on on the good old D300. However, shooting soccer using the same 80-200 on D500 produced a lot more keepers than on the D300. So, no questions about the power and speed of the D500 AF. But it's accuracy shooting static object is problematic. Did I get a bad sample???
