Check out Thom Hogan's blog entry from today - he is indicating bad jello effect on the D3100. Seems he is shooting with one already. Www.bythom.com
Let's hope the D7000 solves this as well as the D3S implementation. I thought I understood the key to solving jello is faster processing horsepower, which the D7000 should have in spades over the D3100?
I am looking forward to video. This will be my first DSLR with it.
