In the digital SLR camera, EOS-1D Mark III that was launched in May this year, Canon has found that some cameras have an adjustment problem with the mirror for AF. The adjustment problem means for the affected products that the focus is not stable or that the Auto Focus tracking is not right when using the AI servo continuous shooting under high temperatures in particular.
The news comes after a letter, written by Canon's Special Retail Channel director Lee Bonniface, was discovered to be circulating the net. The letter states that quality defect with some EOS-1D Mark III units in the market had been discovered, and asks retailers to recall all unsold models of the camera.
The models thought to be affected are those with serial numbers between 501001 and 546561. If you have already purchased a 1D – Mark III, check the bottom of the camera to see if your model may be affected.
Canon will be offering free of charge repairs for those who have purchased a faulty model which will start at the end of November. In the meantime, anyone with any questions should contact Canon's Technical Help Desk on 08705 143723.
