  1. Concerning the issues with printing of 16 bit files, this is normal.

     

    There isn't a printer made with any technology that can manage all the colours that you can express with 8 bits/pixel, let alone 16.

     

    The point of using 16-bit files is that you can do all the mathematical operations needed to make critical corrections on those files without losing accuracy due to rounding errors. Any rounding errors that do occur will have a much smaller effect on 16 bits/pixel than 8.

     

    Then as the last operation before printing you can convert them to 8 bit colour.

     

    With earlier versions of Photoshop you'll need to go to 8 bit earlier as it doesn't support all operations in 16-bit.

     

    The crucial point though is that you can use 16-bit colour while you're making colour corrections and sorting out the levels, which are the critical areas.

  2. For those complaining about the lack of a true spot meter, I'd point

    out that Canon have never offered one in a body below the T90 and

    EOS3.

    They really like 9.5% semi-spot metering for some reason.

    As far as the camera goes, it looks identical in layout to the D30 to

    me, except the controls on the back will be different.

     

    <p>

     

    It is still a mystery to me why the D30 only has 3-point AF

    considering what the Elan 7/EOS 30 has.

    I was planning to rationalise my current collection of film bodies so

    I just had a D30 and an EOS 30 as backup, but it won't be as

    effective given the different AF patterns :-(
