Need lens recommendation for BMCC
 

I have a project that is a 4-camera live talk show, set in a radio station. One medium close-up on each of 3 hosts, and and a fourth wide shot of the whole studio. Given the show's budget and space requirements, they are only considering wall-mounted (or table-mounted) cameras. On the one hand they are looking at PTZs, but I suggested perhaps getting 4 BMCCs with lenses and doing it that way. By the way, the 4 cameras would be edited live through a Tricaster, which I figure should work with BMCC cameras through HD-SDI. I don't actually have much experience using interchangeable lenses, so:

The budget for each camera is about 5-6k total, and with a 2k BMCC, which high quality lenses would you recommend? I'd say that max the price should be 3-4k, ideally less, for each lens.

What is the difference in performance between say:

Also, would I need anything (accessories) else apart from the camera body, the lens, and maybe a UV filter?

I keep on researching this before people have responded.

I need a zoom lens, so the lenses I linked to wouldn't work.

But would the BMCC with this lens work?
