NEWS OF THE L-Mount Alliance ~ Tải Phần Mềm

The recently announced L-MOUNT ALLIANCE between Leica, Panasonic and Sigma has resulted in newsworthy additions that should be of interest to Leica owners.

LUMIX S1R AND S1

Full Frame Cameras by Panasonic

Panasonic introduced two full frame mirrorless cameras, the Lumix S1R with 47 megapixel and the Lumix S1 with 24 megapixel.

This was partially due to the L-Mount Alliance with Leica Camera AG and Sigma which allows both companies to use the Leica L mount on their cameras and lenses. It is planned to offer more than 30 lenses with the L mount by 2020.

The German photography magazine PROFIFOTO was able to test the two new cameras and reported about their performance.

The Lumix S1 has a full frame sensor of 24.2 million pixel CMOS sensor allowing ISO setting up to 51,200. The magazine reports a rather large dynamic range and an excellent signal to noise ratio even with high ISO settings.

The sister model Lumix S1R has a resolution of 47 megapixel. Its high resolution is further enhanced by the elimination of a low pass filter. Aspherical micro lenses for every pixel increases the light detection which in turn results in low noise even with high ISO settings up to 25,600.

If an even higher resolution is necessary, the camera offers a high resolution mode with both models. It combines the information from eight images taken with a minimal sensor shift. The result is a resolution of 96 megapixel with the S1 and 187 megapixel with the S1R which are saved as RAW files. Motion blur will be suppressed by the camera system.

The five-axis IS-system (sensor shift) compensates for camera shake up to 5.5 stops when hand handholding the camera. In combination with a 2-axis OIS (Optical Image Sabilizer) of the Lumix series lenses increses this to 6 stops.

Both models also have a common DFD hybrid autofocus system in combination with contrast detection, allowing the system to respond in 0.08 seconds. The autofocus works down to -6 EV.

Fuirther improvements of focusing and focus tracking is done with the help of AI (artificial intelligence) that can differentiate humans, cats, dogs and birds to help the system anticipate movement patterns. This allows the autofocus to continue tracking the subject even if it turns away from the camera. In portraits, face, eye and pupil detection assist in correct focus.

PANASONIC LUMIX S LENSES

Based on the Leica L-mount, Panasonic has developed three interchangeable lenses for the Lumix S series.

The Lumix S PRO 50mm f/1.4 is a high speed fixed focal length designed as a reference lens for the S Series. But also the telephoto lens Lumix S PRO 70-200mm f/4 O.I.S. and the universal lens Lumix S 24-105mm f/4 MACRO O.I.S. should correspond to the standard used by Leica.

By 2020, Panasonic intends to expand the line-up to at least ten S-lenses, so that more than 30 lenses for the L-bayonet should be available together with the alliance partners Leica and Sigma.
