Galbraith posts exhaustive review of Canon EOS 1D Mark III autofocus situation
Photographer and camera reviewer Rob Galbraith has been all over the Canon EOS 1D-Mark III autofocus situatione like white on rice, and now he’s gotten more thorough than ever: Galbraith released a 17,000-word report detailing his review of Canon’s latest firmware update that everyone hoped would sharpen things up.
It’s going to take you a while to read the whole report, but if you’re a pro shooting with a Mark III or if you’re interested in learning about this situation inside and out, it’s worth it. This guy went into incredible detail.
If you don’t have time to ingest the entire manifesto, here’s a spoiler: Galbraith doesn’t think the problem’s been solved. He says the latest firmware update, v1.2.3, leaves you with autofocus that’s “better, worse or about the same as before, depending on what you’re photographing.”
Galbraith writes:
The EOS-1D Mark III with v1.2.3 loaded offers much better and quite usable autofocus for stationary or slow moving subjects, righting one of v1.1.3’s most pressing autofocus problems. But it now offers middling or even poor autofocus when tracking a low contrast subject that’s on the move, and mixed performance for tracking a subject that’s on the move and the light is frontlit, overcast or indoors. And the raw speed that has typified EOS-1D Mark III autofocus to date, while not gone by any means, isn’t quite as speedy.
