...who are unsure whether their shiny new camera is suffering from the now legendary front/back focus issue, Bob Atkins has posted a quick guide to checking the focus. I’l be testing my camera later today - fingers crossed that it’s OK…

“There are many reports of focus problems with the EOS 10D. There are also many examples where the reported focus errors turned out to be user errors rather than camera errors. For a lot of users the 10D seems to be their first serious camera, their first SLR and their first exposure to the Canon AF system, so operator error isn’t unexpected. However the possibility does exist, and there certainly does seem to be some evidence to support the hypothesis, that some EOS 10D bodies have a problem which manifests itself as focusing in front of the intended subject. It’s also possible that in some cases the 10D has no worse errors than those in film bodies (Canon, Nikon or other), but the ability to do “free” tests in digital reveal those errors! It’s also possible that after being told that there is the possibility of the 10D focusing in front of the desired focus point, some users will find just that, whether or not an objective test shows it to be the case!”
