Received yesterday my A900 with the Zeiss 16-35 and 24-70 and the Sony 70-200.
My first impressions are very good! I had not expected such well built camera and lenses, easy and logical to operate and overall a pleasure to use. FYI I compare with Nikon (D series) and Canon (5D series). Sony has really done a great step towards a perfect camera - if such a thing exists
Hers some examples all done with Aperture Priority and processing and exporting in C1Pro:
First is with 24-70 at 35mm, 2.8 and ISO100
Second is with 70-200 at 200mm, 2.8 and ISO100
Third is with 16-35 at 24mm, 2.8 and ISO100
