Sigma Quattro sensor

Sigma’s CEO sat with Imaging Resource at Photokina, in last September, for another interesting Q&A.

As usual, I listed the main points, focusing mainly on what’s related to future products.

  • This is now clearly confirmed: Sigma is considering the full-frame Foveon option. “We’re studying that challenge”, said Kazuto Yamaki.
  • Sigma is aware of the substantial interest in full-frame E-mount lenses. The interviewers tried to push that idea, but got no more comments on this.
  • Having Sigma’s full-frame lenses declined in Sony E-mount seems attractive at first, but reading further down in the interview, we understand why this is unlikely to happen. The main reason is that the optical design and HSM (autofocus) motor found in these lenses are tailored for reflex cameras. In short, the glass elements that move while focusing are too heavy for the focusing system of mirrorless cameras to work as it should.
  • The price of the 150-600mm f/5-6.3 Contemporary should be “significantly lower” compared to the S version. The difference in image quality between the two lenses is said to be marginal in the center of the frame. The Sports version controls chromatic aberrations much better off-center though.
  • The Sigma 70mm f/2.8 EX DG Macro was discontinued due to a comparatively low demand, and additionally, a special glass element used into it is no longer made. I heartily recommend this lens, if you can find one. The images from it show super sharpness and clarity.

To be released: Sigma 150-600mm f/5-6.3 C

A few readers contacted me after they received the following email from B&H Photo.

Thank you for your interest in the following item:

Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary Lens for Nikon F
(B&H # SI1506005CN)

You are receiving this message because you asked to be notified when this item becomes available. We regret to inform you that this item has unfortunately been discontinued. Please check back on our website for similar or possible replacement items.

We apologize for this inconvenience and appreciate your understanding.

Thank you,
The B&H Web Team

This was caused by B&H assigning the wrong status to the lens (all mounts). It’s now back to “New item, not available yet” as it should.


24-105mm f/4 DG OS HSM Art

A Canon Rumors reader has been told by Sigma that production of the 24-105mm f/4 DG OS HSM Art lens was “on an indefinite hold”, with no hint on what lead to this decision.

The lens, which is offered in Canon, Nikon and Sigma mounts and was supposed to be released for Sony soon, is currently marked as back-ordered at Adorama and B&H Photo.

Apparently, Sigma America doesn’t have any more information for now. Who knows, maybe they are rebadging it as Contemporary.

Stay tuned…

Sigma's multi-layered image sensor

Fotografia.it had a long interview with Sigma CEO Kazuto Yamaki. I wrote the transcript for what brings you here: future Sigma products.

Now, even more than before, I suspect Sigma is looking into the possibility of offering a camera with a larger Foveon sensor. This is clearly not a 2015 product though, unlike new DN lenses (probably).

Lenses for mirrorless cameras

Fotografia.it: The most important part of your production is for digital SLR cameras. What about mirrorless? I see you support MFT and Sony E cameras, but what about Fuji, Nikon 1, Canon M? Do you plan to support also these cameras?

Yamaki: First of all, I think mirrorless cameras are very promising products for the future. […] We always plan to expand our product lineup for mirrorless cameras. […] If there’s opportunity, we’d like to support as many systems as possible. […] But our engineering resources are limited. We have many things to do, many projects to make products of even higher quality, production more efficient… So supporting the new systems is quite time consuming, and requires lots of engineering resources. So we have to carefully select who is our customer. […] We think we define our main customers as photo enthusiasts who like serious photography. So we’ll probably expand our product lineup for those people, who use high-end mirrorless cameras. They are our main customers I think.

Full-frame Foveon sensor

Fotografia.it: In the future, you think possible to have a larger Foveon (full-frame Foveon)?

The new Global Vision series

Naming and categorization are important to make a lens line clear and guide users according to their needs.

I frequently get questions on what exactly is hidden behind the Global Vision labels: Art, Contemporary and Sports. So here’s what Sigma says (in italic), along with a couple of thoughts.

Art lenses

Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression.

Large-aperture prime lenses, wide-angle lenses, ultra-wide-angle lenses, macro lenses, fisheye lenses and more

Lenses designed with no weight and size savings in mind. With the 24-105mm f/4 Art being a notable exception (more on this below), Art lenses offer a large aperture and/or are specialized. Additionally to Sigma’s examples, we can assume that tilt-shift lenses would go into this category.

Sigma News Flash #4

November 20, 2014 Posted in News, Sigma 150-600mm 18 Comments

Sigma News Flash 2

1. As expected, the Sigma 150-600mm f/5-6.3 Sports units are slowly starting to trickle in. The lens hit the US shelves in very limited quantity. Note that we can notify you when it gets in stock, for any of the shops listed here.

2. Sigma warns that the 150-600mm S cannot be used with most film cameras. A member of the DPReview forum, who owns the Nikon F100, asked Sigma for more details. Here is their reply:

It may very well work with the F100 but we cannot test it with all Discontinued cameras. The F100 may not drive the HSM motor correctly or may have different metering circuitry. As we have not tested it we cannot indorse it.

This pertains to all film SLR cameras with the exception of the Nikon F6 and Canon EOS-1V, which are compatible.
