Peter Bendheim has looked at banding conditions for the new D200 in another thread (Bendheim Findings), and shown a "recipe" for this problem. Peter's also rightly pointed out that Nikon should be addressing the question. However. Judging from how Nikon responded this last spring to the focus issues on the D2X, Nikin will only move with some specific findings to present to them to get this addressed (especially in light of the current battery questions, which could occupy centre stage for them). So, I'm not going to ask members of the Cafe to run a zillion tests (I, too, have paying work I need to do, and understand not being able to act full-time in lieu of a testing laboratory for Nikon). Nikon will eventually address this, but perhaps we can derive some understanding of the banding phenomenon and be able to minimise it, just as people minimised shadow noise issues with the D2H and the D100 by using proactive shooting setting(s) on those respective cameras. Here's what I'll ask of members of the Cafe shooting with D200 who are seeing banding issues : Summarise (briefly) shooting conditions for shots with banding; Save the NEFs of any significant banding phenomenon shots for examples; Continue to note any additional (not yet reported, that is) conditions or circumstances for banding; and, Note any changes in shooting settings or conditions that eliminate or reduce the banding effect. Members of the Cafe and other fora have determined some important issues in the past with respect to equipment. I'm unsure if Nikon reads the postings on the Cafe or other fora, but even in their absence, we've found some intelligent workarounds in the past that allow us to address problems. We may well be able to do this here. :Smart: If we develop a significant list of repeatable conditions with examples, I'll take the lead on trying to get this dataset into Nikon's hands for action or pass it on to anyone who has better contacts to do so. Thanks for any constructive contributions to assist the D200 owners in the Cafe. John P.
