Canon 5d mk2 the worst camera ever?

Well, I have to say, I have tried hard. Very hard to give this camera a chance to prove it's worth. I've tried different lenses, tried other peoples versions of the same camera, tweaked the settings and taken it to stores to get checked. No one can fault it yet it absolutely cannot, in any way focus on anything reliably at night. In the day it even struggles. You have to start questioning the camera when you revert to manual focus with your auto focus camera. I am quite simply stunned at how poor it really is. I own a canon eos 3 film camera, circa 1998 which does a MUCH better job at focusing than the 5Dmk2. I'm SO appalled by it I'm getting rid of it at once. I will not shoot with it again. I think I'll either be going back to the 1D mk3 or get myself a 1ds mk2 16mp. I HIGHLY recommend you stay well away from this camera. It's really a complete piece of shit. (but then who the fuck am I to give such an opinion anyway!)
