The Canon EOS-50D was announced as a sister model, rather than successor, to the EOS-40D. The 50D uses the same body as the 40D, but inside is an upgraded 15.1 megapixel CMOS sensor and the next generation processor (Digic 4, versus the 40D's Digic III), Canon claims that the Digic 4 allows for up to 90 photos in a single burst mode. The 3" LCD screen has more pixels than the one found on the 40D, and the Live View preview mode is touted as having been upgraded. Maximum ISO sensitivity has been increased to 12,800 ISO.
