5D mk3 AF point illumination: Firmware update coming April 2013?
One of the first things we noticed when we began testing the 5D mk3 was the un-explained, and to be honest downright annoying change in the way AF points illuminated during a “half-press” for autofocus / metering. Basically, ….the focus points don’t light up anymore. Not until AFTER focus ins confirmed in one-shot AF, and barely at all in AI-Servo mode.
