Got the 6d out of the box , charged the battery , installed sd card . To start with I put on my 50mm 1.8 to have a play . I've heard theses cameras are good at high ISO so I took a few shots inside using natural light on p mode and 1600 ISO .
Now the 40d in my opinion wasn't that good at that ISO so I was very impressed to see the results from 6d ,in my mind it's going to open up a whole lot of photo opportunities .
The thing that I like most is the massive viewfinder , it seems so much bigger when u look through it.
The focus seems spot on , I was put of a bit from buying one after reading about the af system from several reviews , but I also read two or three reviews from guys that have owned the camera for over a year and they loved the af on the camera. Going to have a play in my newly constructed studio .
The general image quality does seem to be quite a bit better than the 40d.
