A new Canon EOS-1D X firmware (rel. 1.1.1) has been released. Among the fixes and new features, two stand out and one of them answers a diffuse user complaint:
- Center auto-focus is cross-type down to f/8 (was f/5.6 with previous firmware)
- AF points are now shown in red when in AI servo mode
The firmware and an updated manual can be downloaded (click here) from the EOS-1D X page. The product advisory:
