Nikon D5000 article.
I'm very interested in the articulated screen, it really frees up viewpoints. But sadly, it is now revealed that in "live view" mode (which you have to use to use the screen for framing) the autofocus is still very slow indeed, which makes it pretty much useless to me.
I'm wondering why it is that Panasonic has managed to make a fast live view autofocus system with the G1 and GH1, and the DSLR makers can't? Some say the lenses have to be made for it, because they have to be adjusted several times every time the camera focuses, unlike with traditional DSLR autofocus (phase), which knows exactly how far to adjust the lens before it starts. So maybe only brand new systems will achieve this successfully. (One could imagine Nikon making a special lens to make this faster, but it does not feel to me likely to happen or be succesful.)
