Japanese-language web site Digital Camera Watch has posted over 2 dozen photos by Yamada Kumi taken with a preproduction Canon EOS-1Ds Mark II and Canon EOS-1Ds (for comparison to the Mark II).
The photos include a range of ISO settings, from 50-3200. The web page notes they were shot as Large Fine JPEGs, which presumably means that the JPEG compression setting was the default of 8. White balance was set to AWB, and the lenses used were the Canon EF 16-35mm F2.8L USM, EF 28-135mm F3.5-5.6 IS USM and EF 28-70mm F2.8L USM.
All are available for download in their original, full-resolution form; the page indicates that only the file name has been changed.
Thanks to Simon Dai for pointing us to this web site.
