60D was a hybrid I hate to this date. Canon misstepped with this one. To that date, I considered xxD being a (semi)professinal line. 70D was a big improvement, a nice and consistent camera and imo it is not true, that it did not provide a sensor performance update. I remember something like 1/3 of stop at least, as well as 70D was the first camera ever, providing DPAF, so by all means, it as a new sensor.It doesn't, although the 50D did. That's one reason those other bodies I listed are a "significant improvement." The 70D also includes AFMA, but I did not list it because, in that case, the sensor performance was not really improved at all over the 60D. The 80D sensor was a significant improvement over the 60D and 70D. Perhaps I should have included the 70D. It also included the 7D's 19 pt. AF system over the 60D's 9 pt. AF, as well as AFMA.
