During the past few months, we either had straight rumors, or various facts/statements leading us to think something is coming. The result is the list below.
Probability is given for 2014 or 2015. Enjoy!
16-20mm f/2 DG Art
The range is very short, but may find its way among photographers if it offers “prime perfomance” throughout. Still, 14-20mm f/2 or 16-24mm f/2 would appeal to more users.
24-70mm f/2 DG Art
The rumor about such a lens appeared after the release of the 18-35mm f/1.8 DC, which was a proof that Sigma could surprise us all with a large-and-fixed-aperture zoom lens. Actually, Sigma is probably thinking about such a lens for the full-frame format, but a 24-70mm with constant f/2 aperture is a tremendous optical challenge. Getting the lens to perform at a good level at f/2 and at both ends of the range is extremely difficult − it is no easy task even for a 24-70mm f/2.8! So what is the solution? Either a more reasonable range, such as 28-50mm or 24-40mm, or a top-performing 24-70mm f/2.8 OS with a cost advantage over the Canon 24-70mm f/2.8L USM II, which is superb but has no stabilization.
24mm f/1.4 DG Art
A necessary lens for the growth of the Art series, and for Sigma to try and establish superiority in the key focal lengths. The land is cleaned.
85mm f/1.4 DG Art
Ditto. See the first hint of this lens.
135mm f/1.8 DG (OS) Art
Likely, but we are not sure about f/1.8 or f/2, OS or no OS. Sony offers a 135mm f/1.8 DSLR lens, so why not Sigma? The combination of f/1.8 and stabilization would make them stand apart again.
120-400mm DG OS f/4.5-5.6 Contemporary
The Global Vision line lacks an affordable telezoom lens. The 120-400mm f/4.5-5.6 DG OS HSM was discontinued a few months ago, and the competitors all have nice offerings. Tamron cleverly entered the segment with their 150-600mm f/5-6.3. See also Thoughts on a Possible Sigma Answer to the Tamron 150-600mm.
—Probability: 70%, but the focal length range may be different.
300-600mm f/? DG OS Sports
Instead of competing directly with the trusted supertele primes from Canon and Nikon by making their own, Sigma could have gone the original way with a zoom lens complementing the 120-300 f/2.8 DG OS HSM Sports. It makes total sense and is in accordance with what they have done in the past.
50mm f/2.8 DG Art Macro
Which focal length will be chosen for the first Global Vision macro lens? The 50mm f/2.8 Macro has just been discontinued, but the reason may be somewhere else, like not enough demand for instance. It could also be a good time to push the envelope (hint: Zeiss offers two very nice f/2 macro lenses).
17-50mm f/2.8 DC OS Art
Ultra-wide DG lens
Sigma will probably not let the world’s widest full-frame lens go, so they should make a Global Vision version out of the current 12-24mm f/3.5-5.6 sooner or later. I think an Art lens will pop up in this segment too, as there is an audience for wider apertures.
Ultra-wide DC lens
The 10-20mm lenses should be updated to counteract Canon’s and Tokina’s options.
Mirrorless (DN) lenses
Logical and expected step-up from the aging SD1 Merrill. Sigma said many times they will continue to make DSLRs, and we know that a new one is in the oven. They are probably putting lots of efforts in getting things right, particularly crucial points like AF and general responsiveness. Now is the camera ready for a Photokina announcement?
Full-frame Foveon sensor
Will Sigma ever have the wherewithal to support the production of a full-frame sensor? We can’t tell, but in the best case, we are at least a generation away from it, so not before 2017.
Another dp Quattro
Is a fourth option overkill? Sigma’s CEO Kazuto Yamaki said it was something they considered due to the demand for more focal lengths. Tele, zoom or ultra wide? I would wager on the latter. Not easy to name though.
Mirrorless interchangeable-lens camera with Micro Four Thirds sensor
Such a camera was probably considered. I would now consider it abandoned.
