New Sigma patent discloses the design of a new L-mount 300mm f/2.8 telephoto lenses

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.

Surprise: Sigma will announce many new DN lenses on September 30!

We already saw the first leaked images of the new 105mm f/2. macro L-mount lens. But Sigma is promising the announcement of multiple new lenses:

We are pleased to announce the holding of an online event “SIGMA STAGE Online”, which is a presentation of new DN series (dedicated to mirrorless interchangeable-lens cameras) interchangeable lenses. It will be held on 30th, September, 2020, from JST 21:00 / CEST 14:00 / EDT 08:00.

First images of the new Sigma 105mm f/2.8 L-mount macro lens

Nokishita leaked the images of the L-mount version of the Sigma 105mm f/2.8 L-mount macro lens that will be announced around September 30.

Sigma 105mm F2.8 DG DN MACRO Art Lens specs:

  • lens configuration of 17 elements in 12 groups
  • minimum shooting distance of 29.5cm
  • maximum shooting magnification of 1: 1, 9 aperture blades
  • filter diameter of 62mm, and a size of φ74.
  • It will be x 133.6mm (E mount 135.6mm) and weigh 710g (E mount 715g).
  • The US price is around $ 799. 

 

 

 

 

Sigma CEO Yamaki says they still don’t know when they will release the new Foveon camera

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.

RUMOR: Sigma unhappy with the progress of L-Mount and Panasonic might make APS-C L-mount cameras to attract more customers

This info is from trusted sources that shared many correct rumors in the past. So I am 99% confident it’s true. This is what they said:

  • Sigma is very, very unhappy with the progress of L-Mount. They are urging Panasonic to focus much more on this system
  • They are really thinking of an APS-C entry level system based on L-Mount
  • They now see Canon as biggest competitor in Video segment

Panasonic stated a couple of times they do not plan to make an APS-C L-mount camera to not cannibalize the MFT system. Well…they might change their mind soon enough and it would be bad news for the MFT folks.

Panasonic is going to restructure the Lumix brand?

Nikkei has posted an interesting “rumor” about Panasonic plans with the Lumix camera brand:

  1. Because of the difficult environment Panasonic plans to do a “structural reform” of the business.
  2. Nikkei writes that this could end in a “collaboration with other companies“.

Sounds like there is a chance they might separate the Lumix brand into a new company with partners (like Olympus is doing). But I guess it might be a different solution: Right now the L-mount partners are allied with separate businesses and ideas. Some kind of more advanced partnership with Leica and Sigma to cut costs and develop L-mount gear together makes sense.
