Version 1.03, for Nikon and Canon, for C and S versions
The latest firmware update improves the AF algorithm of 150-600mm F5-6.3 DG OS HSM lenses and further enhances AF speed by optimizing HSM (Hyper Sonic Motor) drive control.
It is expected to increase autofocus speed by approximately 20%, to a maximum of 50%, during normal shooting as well as when using Speed Priority set through SIGMA Optimization Pro.
