...can't separate wide apertures with more light from DOF considerations, however.

I was able to borrow a copy from CPS. The lens is, hands-down, the best zoom lens IQ I've ever seen. Definitely rivals primes in that aperture range.

As everyone says, price is the only downside, but considering the lenses it replaces that can be sold to partially pay for the new lens, it's not such a catastrophe for an established photographer, pro or amateur.

Jim -- That is a gorgeous set-up there with the 1DX. I don't know how anyone looking at that combo can say Canon isn't competitive or innovative. You've got a near-perfect all-around camera/lens. It would

I agree Gunzorro! I sold my 7D and my zooms to fund the 24-70 ii and the 70-200 ii. I dropped a little cash, but not much. Paired with my 5D3 and a couple of primes I'm pretty well set for a while. While these lenses are a huge cash outlay they are going to retain +/- 80% of their value. The 24-70 is $2,200 new. I have not seen one for less than $2K used. Whether you're an amateur or a pro, I can't think of many instances where you get this type of return on equipment.

I also have noticed little to no CA at all with my two 24-70's I have used.

Actually the Sigma 35mm is rather sharp even to the extreme edges at f/1.4, esp. when compared to other f/1.4 primes. Of course the edges are less sharp than the center at f/1.4, and they certainly get sharper when stopped down, but the lens is usable across the frame at f/1.4.

That's true for close-quarter shooting, but when shooting at mid to far distances the DOF wide-open is usually not an issue.

My point was that some got a 24 1.4 II more for the sharp corner to corner performance on FF at f/8 than to for it's low DOF/lowlight f/1.4 ability and for those people the 24-70 II can replace the fast prime.

At the time, nothing much other than a few zeiss primes and the canon 24 1.4 II or 24 TSE II could deliver that in spades even at f/8-f/10.

I wonder how much better the center sharpness is compared to the new tamron 24-70VC?

The only thing I don't like is the 82mm filter size.

According to Roger's tests, at f/2.8 the Canon is 21% sharper in the center at 70mm and 14% sharper at 24mm. At f/4, the Canon is 8.7% sharper in the center at 70mm and 7% sharper in the center at 24mm. Link: http://www.lensrentals.com/blog/2013/01/canon-24-70-f4-is-resolution-tests

enginyr -- And that doesn't address the weakness the Tamron has on the edges and corners. This important for many types of still photography, making the Tamron far less attractive. For video, where the center is the main area of interest, the Tamron might be considered plenty good enough, especially when the VC is considered.

I'm sure its well compensated for in DxOMark's calculation, but it seems odd that they test lenses on all different bodies. I know that part of what they are doing is showing how a combo works together. I guess they adjust the score of each lens based on the tested attributes of a particular body. It seems like they would have highly standardized, calibrated test equipment so they could test lenses independent of a given body, at least for the sake of posting a score. Just a thought. Love my copy! :-)

I love my 24L II, but in certain conditions, it is prone to significant flare at 24mm and f2.8 - 24-70L II handles flare better.

Let's see:
D800e resolution >> 5D Mk III resolution
Canon 24-70 f/2.8 II resolution >> Nikon 24-70 f/2.8 AF-S resolution

Sounds like some comparison testing is in order

The DXO lens tests are always legitimate; it is their sensor tests that are questionable, says the Canon fanboy .

I typed Rich in my original post instead of Roger. My sincerest apologies!

Roger, how would you go about performing an objective comparison of both lenses and bodies? I assume from what I have seen of your work you have dedicated test equipment that allows you to test independent of outside variables . I really enjoy your reviews. They give good perspective in terms of real world use. DXO might be spot on with their scores, but it appears to me that testing lenses on different bodies, and camera bodies with different lenses, would be a no-no in terms of getting unbiased test results.

Beni, good point!
