The Sigma 200mm f/2.0 optical design described within a Sigma patent

SonyAlphaRumors reports:

One of our Sigma source told us about a new kind of Sigma lens. He said the 200mm f/2.0 development has been approved and we can expect a release as early as in second half 2021. This lens would obviously be available as native L and E-mount option.

Would be a nice lens to have!

Optical design of the 300mm f/2.8 L

A new Sigma patent published today unveils the specs of this Sigma 300mm f/2.8 for L and Sony E

Here are the lens specs (Note: CL means with 1.4x teleconverter attached):

Now usually patents are no guarantee that it will make it into final production. But knowing Sigma’s history I am confident we are going to get this lens for real.

Imaging Resource published a very interesting interview with Sigma CEO Yamaki. Here are some interesting points:

Foveon:

So we continue the development of the sensor, but we cannot commit [to] when we will release the product. There are two issues. The first one is there are some design errors in making the full-frame Foveon sensor. We already have several generations of the full-frame Foveon sensor prototypes. But none of them work properly because of the design error. So we have to correct the design error. The Second problem is a challenge in manufacturing.

Starting from this project, we started working with a new sensor vendor. Yes, a new foundry in the US. They are based in a small city called Roseville (California), which is close to San Francisco. They were the subsidiary of NEC, a Japanese company.

[Ed. Note: Some quick Googling suggests this is TF Semiconductor Solutions, previously TSI Semiconductors (2012-2014), and Renesas Electronics America (2010-2011). As Yamaki-san says, the foundry was originally built in 1998 by NEC. Please note, though, that this is just my guessing, based on a Google search :-)]

FP sales

We are doing extremely good in Japan. The sales here are quite good. But in other markets, sales are not as good as I expected.

24-70mm lens:

We still cannot catch the demand. Because the price is half of the Somy version and it’s also one of the top performing lenses in this category, f/2.8 standard zoom lenses for Sony E-mount and L-mount. I believe it’s the top performer, but to be fair, [I should say] it’s one of the top performers. But the price is half that of the Sony 24-70mm.

APS-C L-mount lenses:

we will probably develop brand new lenses for Leica L-mount APS-C cameras.

Sigma APS-C cameras:

No plan to make APS-C L-mount cameras yet. If we continue the fp concept, probably we will stay with full-frame. But this is just an assumption. We don’t have such a plan right now. But just making an assumption for the future, if the sensor has large pixel numbers like 50, 60, 75 megapixels, you can take a very, very good image using APS-C with a crop mode. So in this case, you can use a very compact lens.

Future of the market:

I guess the market would shrink in 2020, even if we didn’t have coronavirus. Probably the coronavirus issue will escalate the problem. Without coronavirus, I assumed that the market would shrink but probably toward the end of this year to next year, I expected it to hit the bottom, and then level out.

Last year, the quantity of interchangeable-lens system cameras sold in the market was 8.5 million units. But actually, the peak time was 17 million units. So last year was about half. But before digital cameras, film SLR sold about four million to five million units. So it was originally a very small market. So I think it was kind of a boom economy starting from mid-2000 to the beginning of 2010, and then it’s going down to the normal level.

I think probably five to six million is a good number to be stable. Thanks to smartphones, more people are interested in taking better pictures, and some of those people would like to buy high-end cameras. So probably, I think the market size for digital interchangeable-lens system cameras would be higher than for film SLRs. And also because the learning cost is very low compared to the film camera.DE: Oh, yeah, much lower costs than film, that’s a good point. Because now, you can see your picture right away. I remember I would shoot a 36-exposure roll, and sometimes none would come out.

But now my feeling is we’re coming back to more like a five-year cycle maybe, for people getting cameras.

On September 30 Sigma will announce the new Sigma 105mm f/2.8 ART L-mount lens.
