First I must mention that my interest in primarily on the stills side and I came across this site to see if I can find reasonably priced Leica M glass for my NEX-5 and decided to create an account and post in this particular thread because I thought I have some experience with some of the glass you are interested in. My interest in video is very limited unlike my interest in both A and E-mount lenses.
On a full-frame stills camera like the A850 those two make perfect sense. The 24-70/2.8 goes from ultra wide to portrait range while the 85/1.4 excels at portraits. Both lenses are extremely sharp wide open and the 85/1.4 has a beautiful bokeh. On NEX-5 which has a similar sized sensor to FS100, the 24-70/2.8 loses its ultra wide characteristic.
Sony will announce an A-mount 16-50/2.8 (on August 24 with mid-October availability priced much less than $1000) which is supposed to be video optimized, which may address the issue Dermot mentioned above with the aperture opening wide first before stopping down. I think this would be an ideal substitute for both the 16-35/2.8 and 24-70/2.8 together on a crop sensor like S35. My suggestion would be pairing 16-50/2.8 with 85/1.4. In any case, i would suggest waiting for August 24 to see what Sony announces. If you can't wait till the new lenses are available, 24-70/2.8 should serve you well as a general purpose lens and you can add 85/1.4 later if you decide to do so. For the rumors and info about the new gear, you can check sonyalpharumors.com .
Dermot: What is the firmware version on the LE-EA1 adapter itself? It should be ver.02 to support AF. Also, none of the Sony A-mount lenses have image stabilization as the A-mount camera bodies have sensor based image stabilization.
