I have two very specific questions for new D90 owners, particularly those who come from a D80 or D40: 1) Matrix metering --- how is it in controlled tests? I have seen some statements to the effect "it is better but still blows out some highlights". No meter will always preserve all highlights, so this does us little good... Anyone willing to do some controlled tests? On a sunny day find an area with a sharp shadow. Frame a picture so that approximately half the image is in the shadow, half is brightly exposed. Point the focus spot slightly in the shadow area, take a picture. The reframe slightly, point the focus spot to the bright area, take a picture. Repeat with both cameras, compare blown highlights in images 1 and 3, report here. Actual images would be great, but just a verbal description of observations would also do. This is an important question for me, it is THE data point that will determine whether I keep my order for a D90 body alive or cancel it. 2) L-clamps --- will the D80 clamps work reasonably well (from Kirk or RRS), or is a new clamp required. I don't relish the thought of shelling out $150 for a piece of machined aluminum, I can probably find a D80 clamp for under $100 used, it will be great if it works. Yes, I firmly believe that EVERYTHING RRS and Kirk sell is drastically overpriced, but unfortunately there are no viable alternatives when it comes to L clamps.
