It looks good indeed, yes Herb, sunbursts will look excellent in this new camera with the 14-bit image processing. Some more of the very nice new features:
1) -1 to 18 ev, 19 cross-type sensors autofocus system, with sensors spread through the detection area (the top of the line Canon 1Ds mk II has only 9 sensors, all in the central area of detection and a sensitivity of 0 to 18 ev) and the user can make micro-adjustments (no more backfocus?).
2) Automatic, in-camera sensor cleaning system.
3) For the trigger happy people (or for those who don't like to change cards between dives), it can take 2, yes, 2 memory cards at the same time, one CF and one SD. With this feature you can also for example record RAW files on the CF card and JPGs on the SD card, save the same images on both cards for backup or use one card at a time.
4) 1/300 flash sync.
I must confess, this camera is looking awfully good, especially at an MSRP of US$ 3,999... Here is the official Canon site:
