My .02. The BEST run & gun lens, period, is the the 2/3" ENG Fuji HA13x4.5(or newer version)(or Canon 13x4.5). No other lens like this exists for any other format. There is no equivalent in s35, s16, still lenses, etc. As a matter of fact, a few months ago I went to a get-together Fuji had in-town showing off the MK's and their other cine lenses and I told Tom Fletcher that they need to build this lens for s35. I would probably rip the back pocket out of my shorts, I'd pull my wallet out so fast... 99% of my ENG shooting happens with the 13x4.5(I actually own two). Only God know how many off-the-shoulder interviews, live shots, getting locker room sound and post game interviews it has shot over the years on my cameras. Literally thousands upon thousands. I've owned one going back to my last Betacam.
If you're doing a lot of post game for NFL and NBA, I would forget the Fs5 and go back to a 2/3" ENG camera for that. JP and I had a little discussion about that earlier this year(s35 vs. 2/3" for ENG). We kind of live in the same world, just different markets.
I own a Canon 17-120 and use it on my F55 and C300 and while it is a great lens and I would hate to not have it, it is still NOT that lens.
The HA13x4.5 is magic. Just about every ENG shooter I know has or has had a love affair with that lens. For years it was the lens for jib-work and steadi-cam work on video. It still is to a large extent. It is the holy-grail of 2/3" ENG. And yes, a lens like that is needed for s35mm but the physics make it difficult to produce or else someone would have done it by now.
Here she is adapted for use on an Fs7:
