Dpreview interviewed Sigma CEO Yamaki. Here are some key info about the L-mount strategy:

• Curiously enough Sigma had developed their own new mount which was about the same as the L-mount in terms of flange distance and diameter. This before they decided to join the L-mount
• He said too big diamater is bad for the design of slower lenses (they would look ugly as they would be smaller).
• First Sigma L-mount lenses will be released in mid 2019. They will release both: L-mount version of their current 14 ART FF lenses. And special L-mount designed lenses
• Within three or four years he expects Sigma mirrorless mount lens sales to be much bigger than for DSLR. Maybe 70% to 30%.

Stephan Schulz from Leica shared some interetsing details in an interview with Reddotforum:

1) L-mount was not designed for APS-C only. From the start Leica had both APS-C and Full Frame in mind.

2) Mr. Schulz says that there is a big difference with Sony E-mount:

That’s a big difference with the L-mount versus the Sony E mount. They started the mount with the NEX, which was APS, but Sony didn’t have full frame in mind at that time. So, they had some challenges in making the lenses work for full frame. The Leica L-mount is much bigger which gives us more flexibility.

3) This is how the L-mount alliance started:

Panasonic approached us, inquiring whether they could use the L-mount we developed for their planned full frame mirrorless system camera. We started a discussion on how this might work and how it would influence our SL business. Ultimately, we decided to move forward.

4) L-mount alliance is not like the Micro Four Thirds alliance:

It’s different because the L-mount alliance is a closed alliance, with Leica Camera AG as the licensor. Future additional members are possible if the current alliance members agree that the alliance as a whole could benefit from adding more members.

5) Possibly issues with currently existing Leica L adapters:

The adapter isn’t part of the current specification which means lens data may not be recognized and used by the camera.

It doesn’t sounds like we can expect new L-mount members to join any time soon. And I am surprised how direct Mr. Schulz talked about the E-mount flaw!

Photogearnews interviewed a Panasonic UK manager and here are three key info:

1) He makes some Nikon-Canon poke fun and says “you will be pleased to know it has two card slots” 🙂
2) Focus was on the balance between camera and lens
3) Interesting: 30% of the system camera market is Full Frame. 70% non Full Frame (APS-C, MFT)

DC.watch interviewed the three managers of the L-mount alliance and there are a couple of interesting points:

1) Leica is considering selling Sigma and Panasonic L-mount products in their Leica stores
2) There are yet no plans to extend the partnership yet.
3) Yes, other Lens manufacturers can use the L-mount specifications to make L-mount lenses

We got our very first third party L-mount lenses from Reflex:

Ahead of the anticipated release of the Reflex model I. later this year and in a Photokina 2018 preview special, we are proud to present to its audience, the first in a line up of three full frame lenses; The Reflex 40mm f/1.8 comes ahead of a 75mm f/1.8 and a 24mm f/1.8, completing a series of large aperture primes.

The Reflex I accompanying lens series have been optimized for both SLR and mirrorless photography with a compact form factor, carrying a double gauss lens design that signs for an organic look and smooth bokeh, making it a light and ideal daily shooter for both analog and digital photography. Furthermore, it features a clicked/step-less aperture ring for videography and cine adaptation and a large focus-ring rotation angle which enables for highly accurate focusing.

While being presented at Photokina in a native Reflex AR-i, Sony E and Canon EF mount, mirrorless versions will also become available in Nikon Z, Canon RF and Leica/Lumix L mount or to Fuji X and Micro 4/3 via adaptors with the EF version. The lens will be launched on Kickstarter mid November and will ship January 2019.

Anticipated retail price will be under $400.

Note: The specs sheet only mentions two mounts for now. But L-mount will be added later!

Via Chassimages. Thanks Mistral!

Sigma announced their L-mount strategy:

1) Make FF Foveon L-mount camera in 2019
2) No more SA mount cameras
3) Continue to develop and produce SA mount lenses
4) SA-L and EF-L mount adapters to be released in 2019
5) First Sigma L-mount lenses will be released in 2019. First they will make L-mount version of current lenses and then also develop special L-mount lenses only
6) L-mount conversion service will start in 2019

I am super excited about the new Foveon Full Frame camera!
