You don't judge a format capability by its worst or average examples you judge it by its best possible examples. The best films will blow away a 6 MP DSLR on resolution using the best lenses. We are not talking about typical or average conditons we are talking about the sensor resolution of 6MP vs FILM's highest possible capabilty. The best films can be used if desired, so saying 6MP APS as as good as an average film means nothing when comparing the maximum performance limit of each format. jco

Of course, the best films can outperform 6-8MP iun ideal conditions, and that is what's reflected in the spec sheets. It takes 10+MP to exceed 35mm film under idea; conditions, and as the 1Ds mkII has shown you can match 120 film with 17MP. At 10MP and up the lens becomes the real limiting factor on performance with 35mm and APS lenses. -Adam J. C.
