The Sony does 7 frames per second....
But will those 7 frames track a dog or child running towards you in a diagonal ziz-zag in low light using 39 focus points in a 3-D matrix up to ISO 25,600 and keep all 7 frames in focus?
If it does then I'm selling my D7000 and buying one.
Not crticising your choice as it looks great but if you want SLR functions and speed, you'll need an SLR. Sony wouldn't produce an SLR-killer when they've spent millions (billions?) acquiring Minolta and producing some fantastic SLRs over the last few years.
How much did you pay for your D7000? If you want SLR performance, you have to pay for it. With a budget of £450, the Sony is a cracking camera.
There's no point comparing these cameras because at the end of the day, it depends on what you want from a camera, how much you want to spend on one and how serious you are. I could have said "well the Sony is a good one but it's rubbish compared to my 7D". What's the point of me saying that because my 7D cost 3 times the Sony.
