Canon's new EOS 1D Mark III looks like a winner, but I'm a little curious about this new sRAW file format: "In addition to the RAW and JPEG options found in previous EOS Digital SLRs, the EOS-1D Mark III Digital SLR now offers the "sRAW" recording format. "sRAW" has all the flexibility of standard RAW data recording, but at one quarter the resolution and approximately half the file size of conventional RAW images...." Is that new format a big deal? Tell us what you think!
