Just got a used 5D2 and have a question about the CF door. When you open the door, does it not have the spring loaded type hinge of the 7D? The camera is in extremely nice shape, very little in the way of use showing but the door really bugs me the way it just flops open. I know it may be a little thing but still it is annoying to me. Also, if it did have a spring and now doesn't, I may send it to Canon to have them replace the door. Thanks for any info.
