On Saturday I shot about 50 photos of a band inside of a bar with some natural light coming in from the front. I used the D100's ISO setting to 800, and was pleasantly surprised with the lack of "grain" in the resulting photos. Much better then any 800 speed film that I've ever used. Wish I'd used ISO 800 for all the photos. The 30 or so that I took without a flash turned out great, if a little blurred from long shutter times. The mixture of natural and artifical light worked beautifully. The 20 or so that I took using the SB-50DX flash with ALL came out underexposed. This reinforces the impression that I got from previous day's shooting that the D100/SB-50DX combo was under exposing. On the other hand, it has worked great as a fill flash under strong light. Under weak light it tends to over fill. My new rule of thumb is to only use the D100/SB-50DX in bright sunshine and not use them together indoors ever. I never had this problem with the N80. Oh well, new toy... new rules.
To demonstrate this, here's two photo's taken right after each other with the D100 and Sigma 28mm f1.8. The band's name is Lighter. This was take at a concert they gave to benifit the Leukemia and Lymphoma Society at R.T.'s Longboard Grill in San Diego. The first one used ambient light at 1/20 f2.5 and the second with the SB-50DX at 1/60 f6.3. The D100 was set in Program mode, white balance was set to Cloudy-3.
