I was getting ready to pull the trigger on a 1DM4 when a buddy suggested I borrow one from CPS. They shipped to me on the 19 and I've been using itbalongside my 5dM2 and 7d for the last 10 days. It's a great camera but I don't think I can bring myself to spend $5000 on it. It just doesn't seem to offer much bang for the buck compared to my 7d which it would replace. Focus doesn't seem any better and in many cases I find the center point seems to be too big and locks onto something near the center but not what I'm aiming at. The final factor was image quality. It's great but so are the images from the other 2 cameras. When I dumped pics from all 3 cameras in one folder and reviewed them with my fiancé it really wasn't obvious which came from the 1dm4. I had several friends and family review them. In the end I decided that if I was going to spend $5k on a camera I wanted to see more than slight improvements over my current gear. I honestly feel like it would be a really dumb move. Anyone else been there? Maybe there will be a1Ds Mark4?
