On paper the SOny A99 sounds like a miracle Pro DSLR with flawless real fulltime AF, but thats the best case. Im sure this camera will have its flaws, A more pessimistic review can be found here:
Schonbeck: I just returned my Nikon D600 (and 85mm 1.8G) - was very disappointed - the difference from the D7000 was close non existent. Look, feel etc. almost identical (now that is not something negative). Speed and general response was not as good as D7000. Image quality was good but sharpness was huge disappointment and step down from D7000. Same goes for exposure metering that i thought was not as good as on D7000. Not sure if i got a bad example or if the firmware is not yet fully optimized. But as a D7000 owner i would never go for the D600. Instead i am going for the A99 - i want something truly new and innovative that will challenge me to develop my skills. Just my opinion.
Damn, Im a d7000 owner and was gonna get a D600 as my 2nd camera and was hoping to do event photography. Im also drooling over the A-99 but I have a feeling its gonna fall short.
