Re: Wow. K10d + 16-50 mm F2.8 is exactly what I want in DSLR.

One can get a decent guess of weights by looking at the specs of the corresponding Tokina lenses. The optics and possibly some other details were co-developed. SSM+sealing should add some additional weight though.

16-50/2.8 is reported at 610g and 77mm filter thread. Both are alot more than other 3rd party 2.8 zooms, but similar to Canon 17-55/2.8 IS USM.

50-135/2.8 is 845g, Sigmas 50-150 is 770g. Both have 67mm filter thread.
