I'm looking for a portrait/people-photography lens, reasonable price (not top of the range) has to be under $800 type of range.

I've got the 24-105 but it's only f/4 so not fast enough for what I want for shooting people.

I've got the 200mm f/2.8 which is great, but obviously fixed long FL not good for a lot of situations.

So I want f/2.8 or faster, I'm thinking something in the 50-85mm range. I'll use it on my FF 5D Mk 2, but will also need something that works well on a crop camera.

Suggestions?

Doesn't have to be a zoom lens, though obviously that would be more convenient at times.
