I use a Canon 1D Mk IV and have installed all the Canon software.....my question is, if I connect a Canon 650D to my laptop, can this camera (650D) use the 1D Mk IV software to download and process images? I do not have the 650D supplied discs but I assume that the Canon 1D Mk IV software is "backwards compatible"? Can anyone help so I don't have to connect the 650D camera?

Cheers
Richard.
