Leica and Sigma

At Photokina 2018, Leica Camera AG announced a strategic partnership with SIGMA, referred to as the ‘L-Mount Alliance’. The collaboration enables SIGMA to use the Leica’s L-Mount for SIGMA bodies and to offer both cameras and lenses utilizing this lens mount.  The L-Mount lens mount is currently used in the Leica SL full-frame camera system and the Leica CL, TL2 and TL APS-C camera models. L-Mount lenses can be used on all these cameras without adapters and without any functional limitations.

In particular, SIGMA plans to offer a full-frame Foveon sensor body with L-Mount capacity by 2020. The sensor is reputed to be 60 mpx.  Coupled with Leica optics, it should be a killer in terms of resolution.

Dr. Andreas Kaufmann, Chairman of the Board, Leica Camera AG: “For photographers, the ability to choose from a wide range of lenses for their system of preference is extremely important. Especially in the strongly growing market for mirrorless system cameras, users seek increasingly greater product diversity to fulfill a wide range of different photographic needs. We have therefore decided to work together with SIGMA as an immediate response to these needs. SIGMA is a highly respected company that has become firmly established especially in the areas of optical design and lens manufacturing and is able to perfectly complement our existing portfolio of L-Mount products. We are convinced that we and our partners can realize mutual and sustainable growth for all our products.”

Kazuto Yamaki, CEO, SIGMA: “SIGMA is joining this alliance to develop mirrorless cameras benefiting from a short flange back. As SIGMA strives to develop high performance, high quality, and innovative products, this alliance will strengthen the level of completion and the extensibility of our camera system and provide greater user benefits. Leica is a magnificent company that has been contributing to photographic culture for more than 100 years. Together with SIGMA’s unique, high performance and high-quality products, the L-Mount will evolve as an extremely attractive system for users.”

The L-Mount was introduced by Leica Camera in 2014 with the Leica T. A diameter of 51.6 millimeters was chosen to make the L-Mount suitable for use both with full-frame and APS-C sensors. A short register of 20 millimeters enables a short distance between the lens and the sensor, which in turn enables considerably more compact construction – particularly helpful for developments in the wide-angle lens segment. L-Mount bayonets are manufactured from wear-resistant stainless steel and with four flange segments that prevent canting and ensure particularly secure and precisely positioned lens attachment. The standardized L-Mount contact strip ensures trouble-free communication between the electronic components of the lens and the camera – including the possibility of installing future firmware updates for lenses to react to technological advances and exploit the full performance potentials of the lens.

I’ll admit it: I’m intrigued by SIGMA’s Foveon cameras. If anything could turn me into a pixel-peeping tech geek, it’s a Foveon sensor, if only because you can’t help but admire what it’s capable of. The Merrills and Quattros are remarkable for their price – literally medium format IQ in a pocket camera. Plus, they’re wonderfully understated. They aim to do one thing well – produce medium format quality from an APS-C sensor, and they’ve succeeded.  They’ve had to entertain some compromises to reach that goal, but they’re marginal in relation to the payoff, which is stunning detail and color fidelity. Both the Merrills and the Quattros (a slight variation on the 3 layer sensor theme) are built for hard-core photo enthusiasts, nothing superfluous baked into them to appease dilettantes or videographers, no modes, no HDR, no facial recognition or any other bullshit designed with your assumed stupidity in mind.

It’s interesting to me that Leica has chosen to partner with SIGMA, of all people. I’m assuming they’re interested in the potential of the Foveon technology and how the Foveon sensor can resolve Leica’s exacting optics. Additionally, It’s going to allow SIGMA to produce optics to be used on their SL, T and C models, which will undoubtedly prove popular given their (assumed) significantly lower price. This seems to be a partnership that makes sense, focused as it is not on the production of status objects but dedicated photographic instruments.
