I might take the plunge on a 5D when the US rebates hit, but I'm a little worried about the eye-point compared to the XXD cameras. Do any of you glasses wearers find a difference between the XXDs and 5D in terms of ability to see the full viewfinder, or is an eyepiece extender required? I think I'll go buy Best Buy tonight and see if I can play with a 5D (only place in town that I know of that actually displays a 5D), but any input/experiences would be appreciated.
