Steinmueller of Digital Outback Photo has just let me know that he's posted
a review of Canon's EOS-1D digital SLR and the new EF 400mm f/4 DO IS
lens. Of the EOS-1D Uwe says, "Even if the EOS-1D might have low
noise compared to other cameras at ISO 400 and above we will try to stay
with ISO 200 as often as possible. ISO 400 (and higher even more so) look
clearly more grainy than ISO 200 photos (if seen at 100% pixel level)."
