I just had an email from my camera dealer to say that my 1Ds MkIII is in and ready for collection, but he's heard there may be low light focus problems with the camera and he'll understand if I want to cancel or delay.
To cut a long story short this dealer is mainly a Nikon and Leica dealer and doesn't normally handle Canon, but sourced the camera for me from Hong Kong as a favour. The thought occurred that he may be confused with the 1D MkIII focus problem? In any event, does anyone know of any reported focusing problems with the 1dS MkIII?
No. I just stress-tested it for responding to this inquiry. In a room with a single 60 watt bulb shielded by a dark opaque lamp shade ( at 11:30PM) I focused on a black chair about 8 feet away from the light source, indicating an exposure of 10 seconds at f4, and it found the focus very quickly. There is nothing to worry about focusing this camera. It works.
