Canon released new firmware for the 5D Mark III yesterday. Normally new firmware releases are not that big of a deal. Canon, in particular, is notoriously stingy when it comes to including new features through firmware upgrades. (Although they did include audio features with firmware releases for the 5D Mark II.)
One of the big knocks on the 5D Mark III is that the autofocus only works to f5.6. Which is fine for me about 99% of the time. But it did leave my 300 f4 and 2X teleconverter in manual focus land, a place I'm not comfortable in anymore (what can I say, autofocus has spoiled me). The new firmware, released April 30, promised to bring the joy of autofocus to f8 and my 300 f4 with the 2X (f4 X2 = f8).
I downloaded the firmware Tuesday and ran the updater last night while I was editing something I covered earlier Wednesday. Today I tested it. Eureka! It works great.
Okay, so using a 300mm f4 lens with a 2X teleconverter is not something I'm going to do every day, but there are times when I will have to haul out the big glass, and this is the biggest glass I've got.
I tested the firmware and the lens and teleconverter on the sunset as I watched it from the roof of my apartment in Bangkok. Like most of the sunsets here, it was pretty spectacular.
