#1 1/800, f11, ISO 800, 2XIII and cropped from full frame to 2000X1100 - lots of thermal turbulence in this one
#2 1/1000, f11, ISO800, 2XIII -minimal crop - this one had a focus issue, I think. The file shows the central focus point in focus on the animals neck. Maybe 1/1000 was not a fast enough shutter at 1200mm? I hate I goofed this one b/c this was the closest wolf all week.
Overall, the IQ of 600II + 2X III was quite acceptable when the lighting was good (IMO). However, I think I underestimated the shutter speed needed to stop motion of subjects and the combo did not handle back-lighting well (none shown since I already deleted those files before deciding to post this).
