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)?

Sigma News Flash #4

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.

Sigma Quattro camera with Foveon sensor

The Sigma dp1 Quattro is finally in stock at B&H Photo (thanks Tim).

All the accessories are listed in the price guide: Cameras & Accessories. Note that the dp1Q uses the same lens hood as the dp2Q (LH4-01).


Sigma Quattro camera with Foveon sensor

In Europe, the Sigma dp1 Quattro can be purchased at Amazon (see the options) from third-party sellers.

Full-size photos abound in the dedicated Flickr photo pool − a highly recommended browsing if you’re on the fence about this camera, with a free trip to Japan as a nice bonus…

A note on the viewfinders. The Sigma LVF-01 and Sigma VF-31, respectively for all dp Quattros and for dp1 Quattro, are both listed at 229 EUR at Amazon Germany. I’m not sure that it is the final price for those items (the VF-41 for dp2 Quattro sells for 189 EUR) so I would recommend to wait before pre-ordering.
