From what I'm seeing and hearing it looks like Sony has a real winner in the A900, every owner seems to be genuinely satisfied with the camera and the system lenses. On the other hand it seems like the D3x owners are finding it difficult to wrangle the goods from the camera. There are many reports regarding the quality of Nikkors not being up to scratch for the sensor or that they find hand holding the camera results in blurred images. Looks like Sony made all the right choices with internal IS and Zeiss glass. The difference is most evident in the picture threads, A900 shooters are thriving with regular great new image posts while the D3x is dwindling. The pickings are slim even on dpreview and their huge user base.
Way to go Sony, now please add some primes at the wide end so I can join the party too.
PS. Forgot to mention how right was Sony's pricing policy.
