Before buying the D100 I want to be sure for one mode to work on the camera. I've always shoot with Nikon cameras and when shooting with flash in dark interiors, I always shoot in M mode but leave the flash on full TTL. So the camera decides on flash power and I decide on available light (for example I choose 1/8s). On the scale in the viewfinder I observe the proportion of flash and available light changing the latter, and this method gives me excellent results. I just want to be sure that it's still doable with the D100 and SB-80DX or the built-in flash. Recently I bought Canon G2 as a till-I-can-afford-D100-camera and I was very disappointed to find out that Canon doesn't allow me to shoot in this style (which is so convenient). It give me only standard slow-synch which, in dark interiors, leads to too long exposure times. So what I considered a standard with my Nikon cameras now appears unique to them. I assume that Canon can't do that in film cameras as well?
