Sigma 24-105mm f/4 DxOmarked: High End Performance
From dxomark.com:

"When compared against the Canon 24-105mm f4L, to be fair an aging model now, the Sigma outperforms it in several key areas. It has higher peak sharpness at every focal length and at the initial aperture it has better corner sharpness at the longer end of the zoom, which is a limitation of the Canon equivalent.
Another benefit is the just over +1/2 stop improvement in Transmission. But while distortion is similar the Canon has a slight better control of vignetting and slightly lower lateral chromatic aberration.

Sigma are sure to be rewarded as it’s not only a superb performer optically, at $899 it comfortably undercuts the Canon and is well worth taking a closer look."

B&H Photo has received the first shipment of the Sigma 24-105mm F/4 DG OS.

Wow, the Canon 24-120 is a T5.1? That's 1.1 stops below the nominal f/stop. That seems extreme.

I'd sell my soul for an OS version of the current 85mm 1.4.

T/5.6 would be one stop. T/5.1 is slightly over a half stop.

So how did the tests of the AF of moving targets show it?
AF tracking will always be a sticking point on third party gear as many found with the Tamron 24-70.
MTF's are one thing how does it work on a camera??

Really depends what you shoot. Personally, I never AF track with my 24-105 so I don't feel that is an appropriate worry for me. As long as it locks onto focus in one shot within reason, it sounds like a killer lens.

I agree. Now between the Tammy and the Siggy, the choice is aperture vs reach ! (head scratching)

Edit: I did not mention the Canon 24-105 because it is too weak at 70 mm and up (for my taste).

Not really sure who this lens is being marketed for. The performance may be a bit better then Canon but remains to be seen if it is in real world examples.
Also since the Canon 24-105 is a kit lens in many setups it is discounted highly and if the results are only marginal not sure who will buy this lens.
I donīt see why anyone (except Tokina) hasnīt bothered to tackle the Canon FF Ultrawide angle market. I gave up and bought the Canon 16-35 f/2.8L II but feel Sigma/Tamron should have done something at this range. Tokina was extremely tempting with their cheaper 16-28 f/2.8 but with the bulb element not being filter friendly its easier to use the 82mm filters that are the same on my Canon 24-70 f/2.8L II lens with the Canon 16-35 f/2.8L II lens.

My worry with the Sigma is focus compatibility with future bodies/firmware. At least with the Canon 24-105, you can be confident that it will always be supported.

There must be some sample variation as well, as my 24-105 is quite sharp beyond 70mm, even at f/4.

My guess would be that the Dock series lenses (ie the newer 'A' 'S' & 'C' series) are a lot more future proof than previous ones as they are user firmware upgradable .

The sigma doesn't undercut canon's real world price on the 24-105 because it can be picked up so cheap either in a kit, new white box, or from someone selling the lens from the kit they bought, never mind the used price.

Who's going to buy it?

Why is it, we accept the fact that a said lens can have great optical performance, yet not have great AF ability as well ?
This pick and choose philosphy just doesn't seem right in todays age of high performance products.
I understand sometimes lenses have to have certain limits for the price, but If you have a great optical lens, why hamstring it with lousy AF ?

But at the moment the comparison is being made between the L's 'real world' price and the sig's list price .
The street price on the sigma after a while will be much closer to the L's real world price .

I wonder too if there is any difference in color cast from Sigma's coating compared to Canon's. My current Canon outfit is uniform in color cast.

I have always used my Canon 25-105 as a travel lens and have often appreciated its weather sealing (beach photos, tropic sudden rain etc.) and the slight trade in IQ is not enough for me to make a move since the Sigma isn't weather sealed. Color and contrast has been very good, softness hasn't been a big concern. If I want sharper images I switch to primes. I think this Sigma will have greater success with Nikon and Sony users rather than Canon.

I am impressed with Sigma's overall change in focus on quality though and could see other lenses that may interest me in the future. As someone suggested a 24-70 f/2 would interest me... The new 120-300mm f/2.8 DG OS HSM Sports Lens is a lens I plan to rent to experiment with soon. I like the competition they have created.
