There is no advantage for what you're after. However, with the new Panasonic camera and Leitz lens, you can continue to use a shutter speed dial and aperture in their accustomed places rather than having to learn a new set of movements for a new camera. Old dogs, new tricks and all that. One of the things I have noticed in learning to use the E-500 is that the aperture and shutter speed are controlled from a single dial, so their operation is modal. In man-machine interface design it's usually considered preferable to have separate controls for separate functions to avoid modes, rather than overloading controls. Under some circumstances I like to be able to vary both at the same time, which is not possible with the setup as it is. To use the dial in its non-default mode you have to press an interlock, which is not very conveniently placed for me.
