I also like the Pentax idea of fitting the IS inside the camera rather than having it fitted to every IS lens you might have in your possession! Fewer things to wrong.
it works well, except it doesn't do much to keep the price of lenses down. But likely a good step for a low volume mfr.PENTAX LENS PRICES ARE TAKING A LEAP UP TONITE!
some deals to be had on body bundles and the 645D just dropped about $1800 to $7k.
