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.



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:

http://www.sigmaphoto.com/article/sigma-corporation-announces-reorganization-of-lens-lineup-new-products-and-quality-control


Art – These lenses are developed with an emphasis on artistic touch and are designed to meet the expectations of users who value a creative, dramatic outcome. Along with landscapes, portraits, still-life, close-up and casual snaps, these lenses are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much of an expressive scope when capturing architecture, starry skies, underwater shots and many other scenes. This category will be comprised of many focal lengths and designs, such as large-aperture prime lenses, wide-angle lenses, ultra wide-angle lenses, and macro and fisheye lenses.

"This category will be comprised of many focal lengths and designs", might also include Super Sharp Constant Aperture 4.375 Zoom lenses with little or no distortion.

I was hoping Canon might come up with an improved 24-105 II, but this Sigma just might fill the bill.

Excited about this lens, hope it's true, maybe Sigma heard (know) their ain’t going to be a 24-105 L II

Wow, whoever wrote that is good!  ;)

I think it has been obvious for some time that Canon never intended to replace the 24-105L/f4 and the release of the 24-70L/f4 IS USM has confirmed that.

Unfortunately I see no evidence that this lens is real. Sure it would be nice to see, and I'm hopeful that Sigma is preparing to introduce more lenses like this, but this image proves nothing.
It is not a photograph. It is a software render of a 3D model. But that doesn't disprove the lens' existence: Sigma use renders like this as product images all the time.
But someone else could easily have created the model and rendered the image (using the same software?) to look like Sigma's images.

It would be an interesting lens option. Hopefully sharper than the EF 24-105/4 (and my experience with the Sigma GV lenses says that after calibration it probably would be). But at the same time bigger filters and increased weight (and possibly higher cost) would be negatives.
Like all these rumoured Sigma lenses, we'll have to wait and see. But fingers crossed!

weight seems too heavy for this lens

We've been seeing bigger front element sizes on lenses everywhere and I take this to mean that lens manufacturers recognise that with the advent of digital photography people that own *SLRs have become much more interested in IQ.

So if you want smaller lenses with the accompanying smaller filters but you don't want to compromise IQ then you need to move to m4/3.

Or in other words, it isn't possible to deliver a 24-105/f4 for 35mm cameras that is lighter, smaller and has better IQ than the existing lens.

Not sure why someone would go through the process of faking images of a 24-105. It's just not a very polarizing offering. If this was an Art 14-24, seems that would be different!

If Sigma had some inside information that Canon 24-105L will be discontinued or replaced by a more expensive model, this gap can be filled successfully by hypothetical Sigma 24-105.

If the Sigma offering has better IQ and is cheaper than Canon - it's likely to be very successful. However, I believe healthy competition is good for consumers as Canon will reply with something even better.  Interesting development.

I think it's safe to say that the Sigma (hypothetically) will be sharper, have less distortion and much improved image stabilization. I would like to think that Sigma knows that folks like weather sealing in the Canon version and would hopefully include it in theirs. I don't think the added weight will hurt too much since most folks are probably using it as a single lens solution and so intend to leave their tele at home. AF speed and accuracy will be the determining factor as to whether this is a really good lens or a great one.

I have no interest in this lens anyway. I'm still waiting for an 85 and a 135.

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?

If it also becomes available in Nikon and Sony mounts then it will become a "must have" lens for the D800 crowd as it would likely trump the current Nikon 24-120/f4 in terms of IQ and a worthwhile addition to the gallery of available lenses for Sony owners.

Agreed. 

In theory, the Canon 24-105L is a really good walk-around lens.  But I've never been impressed with it's IQ.  IMO, it's really a $800 retail-priced lens.  Not $1150.  It's only marginally better than the Canon 18-200 EF-S lens...  If the 18-200 was an EF, I'd probably get it instead of the 24-105.  It's that good.

If the Sigma is a good 20% better than Canon's and possibly $200 less expensive, I'd be down for that.   ;)

this looks really similar to the Canon 17-55 2.8. Focus ring size zoom ring looks a tad smaller. But still looks pretty real just cause its a similar design doesn't mean its fake. There are only so many designs out there.

I want them to update the rest of their prime line-up though! they have the 35 1.4, now where is a new 24 50 and 85 1.4? thats what I want long as they hold form with the 35!
Also prime tele's! 300 400 and 500! expensive still just for their size but, they'd have to be cheaper than Canon's line-up.

I remember when images of the 18-35 f/1.8 first surfaced. We all thought those were fakes, and look what happened.

I reckon the lens exists, maybe it looks like this or maybe it doesn't. Either way you know Sigma are gonna do something soon!

I can't see it being cheaper than the current Canon version. If it does, I'd be tempted. Well who wouldn't?
