Sigma 24-105 f/4 DG OS Outed?
« on: October 13, 2013, 08:57:49 AM »

Sigma 24-105 f/4 DG OS

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.


We had previously written that such a lens was on the horizon.


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.


This lens is apparently going to be bigger and heavier than the Canon EF 24-105 f/4L IS. It will have an 82mm filter, weigh 885 grams (the Canon is 670g). The lens will have 19 elements in 14 groups.


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.

I wouldn't be surprised if it is real.

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

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.

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

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!  :P

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.

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

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:

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!"

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.
