NOTE: there is a shiny silver "A" on the side of the lens in the picture, meaning this is their "Art" line of lenses - the same breed as the 35/1.4 that has blown away many many people.

It's also proof positive that the pic is a fake. IIRC the Art designation is for lenses with a large maximum aperture.

Meh...  Bigger and heavier than an already existing canon L lens... With the recent sales this lens cannot be any less expensive than the canon.  So I guess the major draw is you get to play the Sigma lottery and have the fun of exchanging for one that does not have some strange focusing problem.

I think there is some room for this lenses, given the Canon L having pincushion distorsion at the low end and CA at the high end. I also have a problem with its cheap plastic feel, and after having used Zeiss lenses for Contax and Hasselblad, I have no issue with the lens being heavy, as long as the IQ is there.

That being said, I think they should have brought this lens out years ago, as Canon has basically saturated the market with their L offering and posioned the well against others who would copy it.

It should be 'contemporary' (C).

Still, I think the lens might be real. Calling this 'A' vs 'C' appeals to the people likely to buy the lens so it makes sense from a marketing perspective.

Lacking however, as with the 35mm: Weather sealing...

And (if this Sigma is real) there's where the 24-105L still wins as a do-it-all travel lens. India would have killed my camera/lens without weather sealing!

Nothing against your post in particular, but what is weathersealing exactly? It's a very nebulous feature that has no real benchmark or specifications. Does it resist to light rain? Heavy rain? A fall in the mud? A sandstorm?

As such, how can you say that it was weather sealing saving your lens? Having and extending design I doubt it can be sealed at all.

My Sigma 35mm has taken some rain and it still works perfectly.

Personally, I think that this lens will not be f4.. It was rumored to be f2 a while ago.. Not saying that it will be but the lens specs are alluding to a larger aperture, at least to me. So heavy!
With regards to weather sealing.. Not having owned an L lens may I ask what exactly is weather sealing? I hear of people taking out non L lenses in light rain and it's fine. Even some of canons L lenses aren't sealed, mind you.

The image is at least dimensionally consistent for a Nikon mount lens. The Nikon flange is 44mm across, so with a 82mm filter thread, 82/44 would give a ratio of 1.86. I measure the flange in this image at 139 pixels across. Multiply by 1.86 and you get 259 pixels for what the filter thread width should be. I've drawn that onto the image and it seems reasonable that this is where the filter threads would go.

If it's a fake, they at least made sure it was scaled correctly.

Sigma is moving in popular segments of Canon
With this lens? not so sure ... Canon already has a very good 24-105 f/4 L IS lens that is selling for less than $700 these days and it is lighter too. However, (if this lens is real) it could be very popular with Nikon & Sony users because Nikon's 24-120 f/4 VR lens is quite expensive and Sony does not have anything like this lens in their line up ... so I think it is more of a "threat" to Nikon & Sony (provided it is priced around $800

That picture of an f/2 zoom proved to be fake. In any case, it purported to be a 24-70mm, not a 24-105mm.

I'm confident this is genuine. The focus ring doesn't resemble any other Art lens so it isn't a composite picture of parts from several existing Sigma lenses, as the f/2 zoom picture was. Speaking of the focus ring, its size is a little disappointing, and I'd have preferred the zoom ring to be closest to the body, a la Canon.

Yea, there's a silver A on the side, but this lens doesn't really fit into Sigma's own definition of what an 'Art' lens is going to be. At least not at the time they announced this:

Sigma 18-35mm f/1.8 DC HSM is an "Art" lens.

Yes, true it is 'Art' and a zoom, but look at that aperture ! I would expect such a revolutionary zoom to be 'Art'.

The oddest part about this rumor is that "HSM" is mysteriously missing. If they wanted to compete with Canon's and Nikon's offering, people wouldn't likely accept anything but an HSM lens ...

If you look at Sigma's 35mm f/1.4 lens, it doesn't actually list HSM on the body but it does include HSM.

What's that sound I hear?  It's the sound of Canon 24-70/4 IS sales imploding

Depends on the IQ and price. The 24-70 f/4 IS is smaller and lighter than the 24-105L, while this one is larger and heavier.

The Sigma has the same focal length range & max aperture, and it extends just like Canon's. So what would make one choose it over Canon kit?

If the lens is real, the filter size could be a clue to Sigma trying to beat Canon in kit lens IQ, e.g. less vignetting & barrel distortion at the wide end & wide open.

That the filter size is larger and the lens being heavier is a big clue that Sigma are aiming to beat the Canon lens for IQ in many areas and this should not be too hard.

The only question this brings to mind is if it becomes to heavy, does it become less "ok" to walk around with it?

The only person who needs to "OK" walking around with a lens is whomever intends to walk with the lens, which boils down to walker's muscles and lens's weight.
