JCL,
It glitched, (differently), for most of our 2 month road trip, summer of '11...it revived itself since then, but now I have the mysterious but not uncommon Error 1, where the cam doesn't 'recognize' the lens. It is the 'kit' lens, as my super wide 10-22 doesn't toss that code. I broke down and ordered a new lens, (a 15-85), and hopefully that will cure this semi-common, but sort of unrepairable Canon glitch. The ~couple hundred thousand shutter activations probably aren't helping either...

Too much Canon glass to step across the road to Nikon...
Thanks for the props!
BR, mD
