Via Time Machine I went back and had a look at the old version of EOS Utility that I had installed. It was ver 2.7.2. According to http://software.canon-europe.com/software/0037084.asp
ver 2.7.2 supports the 1Ds II. One perverse thing about ver 2.7.2 is that it won't let the computer control the shutter when mirror lock is set on the camera. Why oh why....
It appears Canon dropped support for a large number of cameras with the introduction of ver 2.8.1
"Stopped providing support for old models. - Although it is possible to use EU 2.8 with EOS 30D or later models, we have stopped providing support for previous models: EOS D30, EOS D60, EOS 10D, EOS 20D, EOS 20Da, EOS 5D, EOS Kiss DIGITAL / EOS DIGITAL REBEL / EOS 300D DIGITAL, EOS Kiss DIGITAL N / EOS DIGITAL REBEL XT / EOS 350D DIGITAL, EOS-1D, EOS-1D Mark II, EOS-1D Mark II N, EOS-1Ds, EOS-1Ds Mark II
· Added supported Oses: Supports Mac OS 10.6"
Has anyone tried using ver 2.8.1 or later with the 1Ds II?
Also, does ver 2.7.2 work on Lion? (I'd hate to have to buy a product like Lightroom simply to be able to do tethered shooting!!!!)
