As there is lot of discussion about DR charts from Bill with 6d2 release,I checked out d7500 with 80d. Surprisingly 80d is very competitive with best crop sensor (d7500). I was expecting Full stop difference at low iso and consistent 1/2 stop difference at high iso. Instead 80d is within 1/2stop at low iso and very close at high iso. It is almost same at iso 200,1600 and 6400. There is something going on with intermediate ISO,s with 80d where DR drops quickly. Don't know why they decided to cripple 6d when they finally have competitive tech.
