Canon EF 24-105 f/4L IS USM

Canon EF 24-70 f/2.8L USM

Which would you choose for a walk-around? Unfortunately, both is not an option. :blah:

general walkaround i'd want the added range of the 24-105.. and for most general walkaround applications the dof limitation is not going to be an isssue..

I would go for the 24-105 and here's why...

DOF reduces as the focal length changes. So @ 105mm your DOF is shallower than at 70mm at the same aperture.

Of course the 24-70 gives you a bigger aperture, but according to some very rough calcs it would seem there's not too much in it.

i.e. you can get about as shallow DOF from the 24-105 @ f4 & 105mm as you can with the 24-70 @f2.8 & 70mm. Obviously you have to take a couple of steps backward to get your framing the same.

But you also get a lens with IS, a longer zoom range, and at about 2/3 the price.

I would rather have the 24-105 simply for it's versatility. But, when I do get this lens, I am definitely keeping my Tamron 28-75 as well, for those times when only a fast lens will do.

So, I woud recommend the 24-105, then eventually adding the Sigma 24-70 or Tamron, to compliment the versatility of your normal range.
