D100, S2, Sigma, 10D and Digital Rebel have a plastic chassis
*istD has a MUCH larger and a spectacular viewfinder......vs all other DSLRs
*istD features glass pentaprism, like 10D has, better than Rebel's
penta-mirror
*istD viewfinder is therefore brighter
*istD has interchangeable screens....... competitors don't
*istD can be powered by AA batts........ vs a proprietary battery
Lithium, NIMH, nicads and AA alkalines..... get 'em everywhere
*istD is faster.......faster in waking up and operating than Canon
the Canon takes a week and a half to wake up
*istD has smarter autofocus, 11 sensors, 9 of which are cross vs 7 sensors
*istD allows user to choose AF sensor(s) ...... 'automatic' with D Rebel
*istD has PC terminal (D100 and Rebel Digital do not) (10D does)
*istD allows MTF program mode..... nobody else does that
*istD allows instant access to White Balance settings, easier than all
others
*istD allows intentional multiple exposures (no so for D100, 10D or Rebel D)
*istD FEELS like a substantial camera, Rebel Digital feels cheap and
plastiky
