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?

Sony:
Filter Thread 72 mm
Dimensions (DxL) Approx. 3.15 x 6.89" (80 x 175 mm)
Weight 29.63 oz (840 g)

Canon 70-200/4 IS:
Filter Thread Front:67 mm
Dimensions (DxL) Approx. 3.0 x 6.8" (7.62 x 17.27 cm)
Weight 1.67 lb (760 g)

Nikon 70-200/4 IS:
Filter: 67mm
Dimensions: 3.07 x 7.05 (78x179mm)
Weight: 1.87 lb (850g)

Pentax 60-250mm f/4
Filter: 67mm
Dimensions: 3.23x6.61" (82x168mm)
Weight: 2.29lb (1040g)

And to really drive the point home, the Pentax is for APS/C.

Basically 20 elements in a metal tube are gonna be about the same weight and size particularly with up to 200mm f/4 constant. (The Sony actually has 21 elements. Pentax has only 15 but no OSS) If you include the 26mm of mount registration difference, the Sony is a little shorter so it's not just an SLR lens with extra tube length.

Since we're counting oz.'s, I wonder what the Sony weighs without the tripod collar - a collar which doesn't come on the Canon as far as I know.
