Rumored Sigma Lenses

Bummer, looks like the 24-70mm F/2 isn't on the chart...

Sigma at Photokina: All the Rumors



Unfortunately sigma seems to have abandoned Pentax mount in the fast telephoto line... but we'll see, these are only rumored lenses, of course.


How far has Sigma come that (at least I) am hoping for more releases!

QuoteQuote:
One Sports lens and at least one Art lens should be announced sometime this summer.
  • Sigma 24mm f/1.4 DG HSM Art: The much anticipated 24mm prime lens should finally be unveiled.
  • Sigma 85mm f/1.4 DG HSM Art: First mentioned in the May 22 entry, the Global Vision 85mm f/1.4 lens may be announced soon. Side note: having both the 24mm and 85mm announced and showcased simultaneously does not mean they will be released at the same time.
  • Sigma 300-600mm(?) f/? DG HSM Sports: We were first expecting primes (like the patents suggest), but the super telephoto prime segment may be the most difficult for Sigma to conquer, with the pros trusting Canon and Nikon and quickly absorbing the cost of these lenses. So Sigma exploring new possibilities (again) seems like a sound strategy. The supposed focal length range comes from a recent rumor, which did not include any indication regarding the aperture. I bet it will be fixed (after all, Sigma has a 300-800mm f/5.6 lens). A 300-600mm f/4 would nicely complement the 120-300mm f/2.8 DG HSM Sports.
  • Uncertain— Sigma DN lenses in X mount: There may have been some amount of wishful thinking leading to such a rumor, but we’ll see.

Thanks. It wasn't showing up at all in my little 'create thread' box, and then it didn't show up when I posted, so I thought I was OK.

Edited the OP....

The 2,0 24-70 is existing as a one piece prototype with optical function.
I saw it on two pictures,showed me from Sigma.But not clear if it goes in production,this was last december.
1,4 85 A is comming and it looks good for a 1,8 135 A.
Best regards

The current Sigma 85mm F/1.4 is an excellent lens. It will be interesting to see how much Sigma can improve it.

I didn't believe the rumors that it was a F/2.0. That would be interesting but it should be about twice the weight of current 24-70's!

Did the picture look like it was an F/2 lens?

The current 24-70 f/2.8 is 790 grams. (the current 18-35 f/1.8 is 800 or so).

So a F/2 lens could be about 1800 grams (about the weight of the bigma). That's still hand-holdable, but is no fun. They could be doing some expensive-glass optical stuff to reduce the number of elements.

I hope they do, because I think ~1200 grams is the limit for me.

They're also rumored to announce a new 24 mm f/1.4. Never used their old version but I think it was reviewed fairly poorly.

The old version was a 24mm F/1.8 and it was more of a budget lens without the HSM motor. The 24mm F/1.4 Art will be a good lens for Pentax users if its made available, but the 18-35mm F/1.8 is such a good lens I think many people will buy the 18-35mm to replace the primes.

Yuppers. Along the same lines... if there's a hand-holdable, good bokeh, 24-70 f/2.0 coming out... why do I have six primes in that range?

(big assumptions there in the "hand-holdable" and "good bokeh").

@ ElJamoquio,it was a 2,0 24-70.
Extreme fat and looked like a waterhead,Sigma told that it is a Prototype with full optical function but maybe to big,havy and expensive for the customers.
I also think it is extreme hard to hold the quality with a 2,0 in this range.
I also saw the picture of the Pentax 2,0 300 on a Camera and together with the A* 2,8 300.It was soooo big and ugly....Ther was only one prototype and now it is history,later Nikon got a 2,0 300.
This is the look of the Sigma 2,0.
It´s not a secret...
Sigma rumored to announce a new 24-70mm f/2 OS HSM full frame lens next year | Photo Rumors

This patent is refreshed trough Ricoh.
Pentax 70-200mm F2.8 ?????????????So-net???

And,the new telezoom from Pentax looks also very big.Like the Bigma.
But it is not a Sigma or a Tamron system for sure.

I thought that picture was a photoshop?? Current 24-70's use a 77mm front thread. To get twice as much light into the lens, all else the same, you'd need a 108mm filter thread! That's pretty silly, like a 300mm F/2.8 front element. Those 300mm lenses go for ~$3k at a minimum.

That´s the point....possible but to heavy and to fat.
I don´t think that we see it.

If I have counted correctly, this lens has 21 elements. It must be an optical stabilized lens.

I can't understand why anyone would want such a lens. A heavy price to pay both in money and weight for a modest increase in speed over a 2.8 lens...

I counted 17 - the elements are numbered. I excluded OP and CG, as those don't appear to be optical lenses (low pass filter and sensor, perhaps?)

Pentax is never on the list at launch. Most of the time the K-mount is released several months or a year (18-35 F/1.8) after the Canon version hits the shelf.

I agree with Winder, the Sigma Art 18-35mm f1.8 is indeed excellent, and it did replace a few of my wide angle primes (Except the F series which are delicious like gummy bears) I have a few Sigma EX lenses (just sold the 100-300mm f4 EX DG to buy the EX 300mm f2.8 prime), 18-35mm IQ is outstanding (and i do own a excellent copy of the EX DC 30mm f1.4), the autofocus is quieter than any of my previous HSM lenses, the Sigma Ex DG 85mm f1.4 and the 70-200mm f2.8 Macro II (but not as fast or accurate as the 70-200mm HSM). Sigma truly seems like its pulling its lens designs from specs found in some UFO crash site they've uncovered in the past few years. If Sigma continues to produce such high quality lenses and the other manufacturers don't follow suite, it could very well be the most popular lens manufacturer in the near future.
