I had high hopes for the FE system, was thinking that I'd eventually switch from Fuji, but it seems the size and weight advantage are not there?

Filter Thread 72 mm
Dimensions (DxL) Approx. 3.15 x 6.89" (80 x 175 mm)

Canon 70-200/4 IS:

Dimensions (DxL) Approx. 3.0 x 6.8" (7.62 x 17.27 cm)
Weight 1.67 lb (760 g)

They should hire someone from Pentax to design the lenses.

The argument of Timbukto seems valid to me: You save weight with the camera by reducing the flange distance. But for best IQ you want the light coming as straight as possible on the sensor so you introduce "some distance" within the lens. Thus the lens gets at least longer and a bit heavier.

On the other side, the Canon is -while a good performer- not a new lens and thus also the IS is not state of the art. So maybe the Sony is more modern design with an even better performans.

But of course maybe Canon is simply one or two steps ahead as far as lens designs are concerned ...
