Witam.
Osobiscie nie, ale polecam wywiad z Chuckiem Westfallem czyli gościem z canon USA:
1/ The overall AF system speed of the EOS-1D X including lens drive is superior to that of the EOS-1D Mark IV on a lens for lens basis. The overall AF detection speed of the EOS 5D Mark III is superior to the AF detection speed of the EOS-1D Mark IV.
2/ The level of AF precision for 5 of the central area AF points on the 61-point sensor (i.e., the dual X-shaped cross-type points) is superior to the level of precision for any of the AF points on the 1D Mark IV.
3/ 21 cross-type AF points in the central area of the 61-point sensor are functional with maximum apertures as small as f/5.6; None (zero) of the cross-type points on the EOS-1D Mark IV are functional as cross-type sensors at maximum apertures smaller than f/4.
4/ The 61-point AF sensor has twice the low light sensitivity as the 1D Mark IV’s 45-point AF sensor (EV -2 vs. EV -1).
5/ The 61-point AF system supports AI Servo III, which is superior in subject tracking stability and consistency compared to AI Servo II found on the EOS-1D Mark IV.
Czyli jednak piątka
