because it doesnt break the SLR Philosophy
U still see what u are doing because u don't look through the sensor.
In the tele it does matter also.
Seriously i don't get that.
How different is shaking glass from shaking sensor if you still look true the prism-mirror-lens in both??????
Are you sure you not meant live view?
@Pavel, you cant use old nikon flashes with digital nikons due to lover triggering voltage in digital camera. You can still use them in manual mode if you put safe hot shoe between camera and flash.
Im positive all brands have same "problem", including pentax.
