Excuse me for quoting literally Phil Askey -I hope with his kind permission- "A check of the detail crop however shows that at ISO 1600 and 3200 we're losing detail to the smoothing effect of noise reduction. A quick scan of the graph below shows that noise levels between these cameras are actually quite similar up to ISO 800 (with or without noise reduction), with noise reduction switched Off the D2X's ISO 1600 noise is marginally higher than that of the EOS 1Ds Mark II. Set noise reduction to High and you get the cleanest looking images and lowest measurable noise levels but at the expense of image detail (see samples below graphs)" "In development terms this new sensor may not be as mature as those found in Canon's digital SLR's but it real terms it performs almost as well, the only difference seems to be Nikon's choice of standard sensitivity range which is ISO 100 to 800. Turn off the High ISO noise reduction and shoot at ISO 1600 equiv. (HI-1) and noise levels will be higher than we'd like, turn noise reduction back on and you begin to lose detail (my preference is keep the detail as the noise isn't that objectionable)." "Having now matched the in-camera sharpening we can see that while the Canon's resolution advantage can be seen in areas of fine detail it's not a storming lead" Leica DMR option for 1.3 crop sensor is an economical decision consequence of cost influences and it's the first time I see Leica not going to the top notch absolute quality but is doing concessions to practical factors. May be it will be necessary for survival. Felix
