Sony A580 Best Low Noise Crop DSLR in Sony Line up?

Wow, that got off track in a hurry!  Again, wasn't arguing sharpness or anything else guys...Didn't even mention it. Take all the bells and whistles away from the Nikon's and the Sony's, then compare the Low noise at High ISo, and Nikon D700, D600, D3,D4 will surpass every time...The A99 is a great Camera, no argument there...But for price and performance, I'd still take the used Nikon's mentioned...Minus the D4...waaay overpriced, great non the less.  I'll leave this for you all to argue, I made my point and am sticking to it...Peace my friends...Be safe...have a Merry Christmas and a Happy New Year!
