FOr those getting a 1Dx, moving from the 24-70 to the 24-105?

Just a thought.

Almost all of my work is weddings and when choosing what lenses to use I nearly always go for the fastest I can, be they primes or zooms.

With the 1Dx being so much better in ISO performance the 1 stop speed advantage of a 24-70 doesn't 'seem' to warrant using it when you compare it to a 24-105.

With the extra reach, IS, reduced weight in it's favour is it something you've considered yet?

For me the plane of focus on the 2.8 is nice but a lot of the time impractical when shooting a couple at an angle when F4 would be more suited.

Greetings - Plan to get the 1DX but plan to stay with the 24-70L in spite of better ISO performance. It can always be stopped down to f/4 and the 5D Mark II will become second body.
Cheers,
John

Great point.

f/2.8 isn't always about getting more light in

yes I would do it, the 24-105L was my cash cow when I was shooting portraits for local school, the extra reach is great for candid.

What's very exciting is being able to use a 100-400L in a church.

At f2.8 you might get a shutter of 1/30th, at f4 with the IS, you'd get that same shutter but with different DOF

Recently i've found myself shooting my 24-70 at f4 for groups to get enough DOF, and switching to my other body and different lens all-together for singles or places where i want the DOF isolation that 2.8 & faster would give me... so i may actually switch... May...not sure...

Thinking about it, the 24-70 70-200 combo could potentially be replaced with the 24-105 and 100-400?

Extra 200mm of reach there.

I've got the 24-105 f4 L and the 70-200 f4 L and the 100-400 L, just wish I could afford the 1Dx to try them all on. The 24-105 is my most used lens whether its on my 7D oor my 5D2, usually it's the 70-200 next in line then a tie between the 100-400 and my nifty fifty.

I'd stay with the 24-70 and 70-200. Are you hunting for birds with the 100-400 at a wedding?

Hey, Buxted Park, 100 people spread over an area the size of an Olympic swimming pool

I would suggest investing in a fast telephoto prime. 300 2.8 or 400 2.8 should work.

Indeed it would but that's a heavy, costly piece of glass without a zoom function.

May as well throw them a football lol.

I guess the zoom would be the best option.

No offense OP, but you're dropping $7k on a body - I'd suspect you know what would and wouldn't work for your needs.
