<p><strong>Sigma 24-105 f/4 DG OS

</strong>We have received an image possibly showing a Sigma 24-105 f/4 DG OS lens. As with any image from an unknown source, there’s always a possibility it’s a fake, although those are becoming more and more rare.</p>
<p>We had previously <a href="http://www.canonrumors.com/2013/09/sigma-24-105-f4-os-on-the-way-cr1/" target="_blank">written that such a lens was on the horizon</a>.</p>
<p>Below is what we’re told is a soon-to-be-announced Sigma 24-105 f/4 DG OS. We’re told an announcement should come some time in the next 6 weeks.</p>
<p>This lens is apparently going to be bigger and heavier than the <a href="http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5574981434&toolid=10001&campid=5337238466&customid=&icep_item=300987513612&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg" target="_blank">Canon EF 24-105 f/4L IS</a>. It will have an 82mm filter, weigh 885 grams (the Canon is 670g). The lens will have 19 elements in 14 groups.</p>
<p>I will leave you guys to debate how legit the photograph is below. To my eyes, it looks pretty good. We’ll try to confirm this with a couple of our Sigma sources.</p>

I wouldn't be surprised if it is real.
Sigma is moving in popular segments of Canon

 

[baervan]

sounds a bit unnecessary the canon is not even that expensive..

i think sigma should aim for an ultra wide zoom or prime, i think they will see big bucks if the come out with a good 14mm 2.8

 

[Ellen Schmidtee]

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.

 

[Ricku]

This is highly interesting! Simply because Sigma's version will be waaaaaaaaaaayyyyyyy sharper than the L.

I think the difference will be even greater than the difference between S35 and 35L.. And that's a big difference. :-X

 

[wsgroves]

I am sure it will be superior to the canon offering, however....do you guys think it would sell enough seeing as how the canon offering is so "cheap"?
Could they have the quality to blow it away and still keep the same "low" price?
That would be interesting to me.

They kinda did with the Sigma 35. That lens is a bargain and it blew away the 35L completely.

I've said it before and I'll say it again. Sigma is not the company they used to be. They have earned my respect with their latest offerings, and now I'm hoping for more!

 

[Chris Jankowski]

19 elements in 14 groups is a lot of potential to correct image imperfections and is likely to mean that the lens will be sharp corner to corner at F4. if so, then I'll sell my Canon 24-105 and buy this lens if it is as reasonably priced as the 2 previous Sigma Art offerings - 35 F1.4 and 18-35 F1.8 APS-C. I would probably also sell my 50 F1.4 and 35 F/2 IS. This lens will replace them all.

 

[AJ]

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

 

[Sporgon]

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:

[Joe M]

Rumours don't excite me as much as announcements. This one is a little tantalizing though as I'm sure anyone who has used or is still using the Canon is happy with it but wouldn't mind a little less wide end distortion, along with a little more sharpness in the corners as well as better performance in the long end. I've so far resisted using any non-Canon gear (I'm sure I'm the type of customer Canon just loves because of this) but if this lens can significantly improve upon the Canon version, it may prove tempting.

Standard zooms should fall in the Contemporary category. Hint that it's a fake? Or maybe Sigma is rearranging their classification according to people perception? As in: "it's Art like the 35mm, must be good!"

 

[Hesbehindyou]

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

 

[dadgummit]

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.

 

[johnhenry]

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.

 

[cellomaster27]

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.

 

[bchernicoff]

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
