Hi All,

I recently sold my 7D + EF-S 17-55 2.8 IS USM. My new 5D Mk III will be here Friday and I need a walk around/vacation lens to complement my 70-200 f2.8. I've been contemplating:

Canon EF 24-70 F2.8 II <--I have this coming from LensRentals Friday as well for a test
Canon EF 24-70 F4 IS
Canon EF 35mm F2 IS

I'd prefer to stay away from 3rd party(Tamron's 24-70).. Mostly because I'm weird like that.... My uses will be:

1. Landscape
2. General walk-around use on vacations
3. Motocross(Although it's possible I won't do this as my 70-200 should cover that situation)
4. Pictures of my family(new baby, Christmas pics, etc..)

Price isn't really a concern as long as the price is just for "1" lens that will cover me. Can I get by with the 24-70 F2.8 II and it's lack of IS? Will the F4 of the 24-70 F4 IS make me wish I had the F2.8? Will the prime leave me wanting more length? Will Canon custom build me a 24-70mm F2.8 IS USM with perfect image quality?

Thanks for any replies!
