That was me who asked this question first about Dmax for b&w film with this scanner. I haven't received any answer but I carried a simple test myself. I don't have the scanner yet but I measured the Dmax of my negs with a professional densitometer. The results are the following: B&W - the highest value recorded was 2,35 (very dense sky area in a picture measured for the shadows, the sky was not intened to show any detail) - the highest value were detail should be preserved was 1,85 - most often the highlights have value of 1,5-1,7 COLOR NEGATIVES - the highest value recored was 2,60 - usually highlights have the value of 1,75 COLOR SLIDES - the highest value was in the filmleader 3,48 - the darkest areas where detail should be preserved had the value of 2,9-3,0. Dmax of 4000ED for b&w film is said to be 2,3. My conclusion (without seeing the actual scans) is that this machine should cope with my b&w negatives as most of them have highlights of about Dmax 1,7.
