I have been using manual exposure mode almost exclusively so far ( I did try program/Av mode with a couple A lenses and was not impressed with the consistancy, some overexposed too much and some underexposed too much depending on subject). I think the problem with AE on this model ( istDS ) is the camera doesnt have that much exposure latitude (much less than neg film), and precise exposure is fairly critical to a really good image. I just guessimate exposure, shoot, and tweek manual settings via f-stop or shutter speed till I get a good histogram and then shoot for real. I know this technique wont work for fast shooting, but it works well if you have the time to do it and a steady subject in steady light. And its a HELLUVA lot easier than shooting in AE and tweeking the exposure compensation over and over again when the subject brightness changes but the incident light falling on the subject doesnt. I would like more exposure latitude on a camera (is K10D better in thie regard?) which would in effect make the AE much more usable. That and a working apeture cam sensor for K/M lenses to implement full AE properly for those lenses too! (Guess you know that already).
