Looks like Canon is still tweaking the AF algorithms, but at least they're being receptive to customer feedback. New firmware was released today (well, 'tomorrow,' but world time helps) for the 1D/1Ds Mark III with the following remarks:
Haven't noticed AF issues with the 1DsIII in AI servo, but perhaps things will be even better underwater1. Includes the following new features that were frequently requested by customers to the new firmware.-----1. Direct selection of AF points by the Multi-controller is added to C.Fn III-9.
-----2. Alternate access to Exposure compensation is added to C.Fn IV-3.
-----3. (1D Mark III only, already included in 1Ds Mark III) With the camera's External Speedlite control menu, Flash function settings can be used to set the Wireless setting and Zoom.
2. Improves the stability of AF accuracy in AI servo AF when shooting extremely low-contrast subjects.
As always, you can download from Canon's firmware page. Who wants to be the first to update? ![]()
