A reported roadmap for Sigma has shown up over at SigmaRumors.com. They’re told that Sigma’s 24mm f/1.4 ART lens has been delayed until Q1 of 2015. This has been a rumoured lens for quite some time.
Also mentioned are a 14-24mm f/4 Art which makes a lot of sense. Also mentioned is a 16-20mm f/2, which seems a bit constrained on the zoom range, why not just make a 16mm f/2?
Sigma has opened up about their future plans to Focus-Numerique and what sorts of lenses and products they are, and are not developing.
- Sigma will update their 24-70mm f/2.8 EX DG HSM (with an f/2 version?) and 70-200mm f/2.8 EX DG OS HSM lenses.
- Sigma’s next DSLR will have a brand new design philosophy.
- Sigma is not interested in developing a new mirrorless interchangeable camera for now.

Is Sigma getting ready to enter the world of professional cinema lenses? It seems like a logical next step for the manufacturer, as they have become quite aggressive in the higher end DSLR space. While Sigma didn’t flat out say they were entering the market, they also didn’t deny it.
Sigma’s CEO Kazuto Yamaki left the following hint recently in an interview with Resource Magazine:
“How could one of the greatest innovators of lens technology in the world not be producing lenses for high-end digital video and motion picture cameras? With such high standards, cinematographers seem like a natural market for Sigma. When I asked Kazuto about this, he simply smiled and said the two words that make every tech writer crave more: “No comment.” It looks like Sigma may still has a few more tricks up their sleeve…”

A summary with the probability of upcoming Sigma lenses has appeared on sigma-rumors.com. Most of the lenses mentioned have been written about here in the past. Sigma’s focus over the last 2 years has been on high quality and affordable offerings, there’s no reason to think that won’t continue.
The most likely lenses to appear next would be:
- 24mm f/1.4 DG ART
- 85mm f/1.4 DG ART
Both of these lenses have a chance to appear at Photokina in a couple of months. I’d say the 85mm f/1.4 is a given, but the 24mm f/1.4 could fall to later this year or early 2015. With Zeiss expected to announce their Otus 85mm f/1.4 in September, Sigma could play spoiler with an optically great lens with autofocus at a much cheaper price.
The other lenses according to the site with the highest probability of happening are:
- 24-70mm f/2 DG ART
- 300-600mm f/? OS Sport
We’ve heard about both of these in the past, and I’m inclined to believe the supertelephoto zoom is definitely something Sigma is developing. The 24-70mm f/2, I’m not 100% sure on. If Sigma wants to differentiate themselves from the Canon and Nikon offerings, then such a lens would do the trick.

Sigma Corporation of America to Release Two MTF Charts for Measurement of Lenses
Company releases the data of Geometric and Diffraction MTF charts for Global Vision Lenses
RONKONKOMA, N.Y., — February 3, 2014 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, today announced that the company will now release a Geometrical MTF (Modulation Transfer Function) chart in addition to a Diffraction MTF chart when measuring the performance of all new Global Vision lenses.
MTF charts are important because they help photographers better understand the optical quality of lenses. Sigma has traditionally released Diffraction MTF data because it takes the diffraction quality of light into consideration, which can dramatically affect the data outcome. Diffracted light exists at every aperture, giving photographers a more accurate measurement of how the lens will perform in real life. Although Geometric MTF data is easier to measure and calculate since it does not consider the diffraction quality of light, it tends to show higher values in the graph and less defined results.
“As a family-owned organization, we hold ourselves and the products we design to a very high standard,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Our customer’s expect high quality products and by sharing both MTF charts for all our new lenses, we are able to help guide them in making the most informed purchase decisions based on how our lenses will perform in actual photography situations.”
As a leader in technology and innovation, Sigma Corporation is committed to showing the true value and quality standards of all Sigma Global Vision lenses. Every lens is tested with Sigma’s proprietary modulation transfer function (MTF) “A1” measuring system before being shipped from the factory in Japan. By making both MTF charts available, Sigma is providing its customers with accurate measurements of its lenses and giving photographers a chance to see the full potential of Sigma’s lenses.
