....No mention of what's needed most for shooting videos though: auto-focus with subject tracking and in-body image stabilization. I recently purchased a Nikon D5000 to get my first taste of DSLR HD video, which I'll write more about later, but the lack of in-body image stabilization when I'm shooting with my f/1.8 35mm prime makes for some nausea-inducing videos unless I'm extremely careful.
In-body IS is a true boon: am able to get wonderful (albeit SD) movies with my now "old" Canon S3 IS. In fact, these are so much better than had anticipated that now use video mode on a fairly regular basis. But BEYOND movies, IS is great for all sorts of hand-held still shots, and having it "in-body" certainly helps keep the costs of extra lenses down.
Obviously that is not a problem with the S3, but when we picked up a Pentax K10D for our youngest daughter (and now no-longer-resident Photography Major), the sensor-based anti-shake system was one of the decisive purchasing points. (Along with dust & "weather" seals, good reviews, & a very competitive price...
