Galbraith continues analysis of 1D Mark III AF issues By
Michael R. Tomkins, The Imaging Resource (Thursday, December 13, 2007 - 15:56 EST)Our good friend Rob Galbraith, professional photojournalist and proprietor of the Digital Photography Insights website, has posted an update to his analysis of autofocus performance in Canon's EOS-1D Mark III digital SLR.
Rob has been following this issue very closely from the start, and has put an absolutely staggering amount of time and effort into helping Canon resolve the issues that can cause inaccurate AF in outdoors shooting, particularly in bright sunlight. His latest update looks at Canon's current fixes - a revised sub-mirror mechanism and updated v1.1.3 firmware - to see if they offer a solution to photographers shooting the 1D Mark III. The answer so far looks to be a resounding "maybe", with clear improvements in some areas, but still sub-par performance in others.
If you're considering purchasing the EOS-1D Mark III, the article not only updates you on the issue, but also gives some idea of whether you're likely to come up against it in your own shooting. If you already own a 1D Mark III, it will help you in determining the best course of action in resolving any problems you may be experiencing. It also provides some insight into just how far both Rob and Canon are going to try and solve the issue, including multiple trips to Phoenix AZ (!!) where environmental conditions are rather warmer and sunnier than Rob's home in Calgary, Canada.
