Considering most of the stuff in the camera is electronics, I sure hope so.
Anyway, this is why I usually advise against buying used, especially if it's also old. With electronic equipments, there's always a chance of it to suddenly die without warning. The older it is the greater the chance, and if your luck isn't so good...
I would've waited for the extra 6 months and just get a brand new 5D3 instead. Because now you still end up waiting anyway.
BTW, Win8 Metro is crap.
My original thread went through my reasoning. I'm thinking that the depreciation on the MKIII will far outpace a used 5D over 6 months. I can learn some about Canon during that time and not have to layout $6K today and in the end wind up with a MKIII and a backup body for just a few hundred more than the MKIII today. I'm guessing I'll have the replacement by next weekend, so only a few days delay.
My reasoning my be flawed, but time will tell. Part of the reason I chose KEH was the 6 month warranty - very generous if you ask me. Many of the other big retailers offer 90 days and Ebay? Well, 0 there in the majority of cases. I never buy the extended warranty on electronics, but in this case I really did through KEH because I may, with patience, have won a bid for a little less for a camera in similar condition. However, knowing these things can happen, I paid the extra for piece of mind.
My used 24-105 f4 L from KEH? Immaculate. I really can't believe it is used. It is the one I used for the only pics I got from the 5D. I honestly anticipate zero problems there. Great value as far as I'm concerned. Time will tell on that one too though I guess.
I am still very excited about the 5D. Although a little "antiquated", it is still a fine camera that does all I need it to do.
As another poster or two offered, these things happen. It doesn't make me happy, but I'll get over it. No hard feelings for Canon. And I know folks today that are still using a 5+ year old 5D very happily, so I'm guessing most will last. If not, then I made the wrong call.
As for Win8 Metro? You hit the nail on the head there. May it die a quick death.
