Sigma 17-70 C on A77 AF/MF toggle.
11 months ago

Lens switch set on AF.
When I toggle the AF/MF button on the A77, the MF symbol shows on the display.
The auto focusing is disabled but cannot do manual focusing(manual focusing ring if locked or stiff).
Is there a problem with the lens or is it that this function cannot work on this lens.
