Best body/lens combo for upcoming event?

So in addition to the gear in my signature, I just purchased an 85mm 1.8 and have a 35mm f/2 IS coming any day now.

I'll be shooting a work lunch banquet next week. It's an indoor venue so low light, but I've been asked not to use flash.

I'm thinking I might use both of my bodies. I was considering experimenting with just primes, using the 35 on the 6D and the 85 on the SL1 for when I need reach. Another option would be my trusty 24-105 on the 6D and the 35mm f/2 on the SL1.

Any suggestions? This is the first time I'm gonna try shooting with two cameras.

I think your plan of using the two primes on two bodies sounds like a good one.

No harm in trying the Sl1 in low light but I have been disappointed with its performance in such venues.

Probably my lack of patience or other user error. But don't expect 6D/5D3 performance with the Sl1. And I would not go higher than 1600 ISO.

(I have used the 35 f/2 IS on the Sl1 and love it in good light.)

In all fairness, I was also a bit disappointed in the 6D for moving subjects in low light. But that's a minority view as well.

For your event, nevertheless, given what you have to work with (and assuming not much movement on the subjects) I would use all three lenses on the 6D. They are all excellent lenses for your stated purposes.

I agree with Eastport on this but would like to add, set your min shutter speed to 60. If I use less then 60 my keeper rate drops, people move all the time.

I would bring the SL1 as a backup and keep it aside. I'd use just the 6D and switch lenses when needed, between the 24-105mm and the 35mm.

If it is dark like you say, you should use the 6D as much as possible and crank up the ISO.

You're Batman, you can do whatever you want.
