Never wanted, nor owned a 5D2. Still, many did enjoy their 5D2's.
It's weird with me. I think I am a fool for the marketing... I started with an XS then upgraded after 2 years to a 60D (mostly because of the cross type AF points and shots per second). When I had the XS, the mkii was my dream camera... stuff that I would love to have, but simply would never be able to afford to get. But then everyone said the auto focus was weak, and the 5d mkiii was just so much better. And then the mkiii became my dream camera which was really out of reach when it was 3500... but now that you can find one for 2500... it is still expensive, but not impossibly so.
Back when the 5d mkii packages were selling for around 2200 with the body, 24-105 and a printer... I thought about getting one. But I couldn't pull the trigger because of the shots per second and the auto focus, and I think I would even miss the crop factor. So the mkii just simply became something I had no interest in.
And I think where my biggest hang up is... is that I don't want to pay for something that will depreciate so quickly. I love that lenses hold their value, but not bodies.
