Introduction | 2007 |
The Panasonic Leica D Summilux Asph 25mm F1.4 is an interchangeable camera lens announced by Panasonic on March 7, 2007.
The lens uses 10 elements in 9 groups, arranged as a double Gauss type, with one aspherical, three extra-low dispersion (ED), and one super ED element. It was announced in March 2007, with availability starting that April. [1]
As reviewed in 2010, the lens exhibited little distortion and offered close to maximum resolution wide-open, improving slightly at f/2. [2] Resolution on the frame's edge was weaker, though, due to chromatic aberration and visible coma at maximum aperture. [3]
The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) and mirrorless camera design and development.
The Lumix DMC-L1 is Panasonic's first DSLR camera, and was announced in February 2006. This camera adheres to the Four Thirds System lens mount standard, making it the first non-Olympus Four Thirds camera, and thus confirming that the Four Thirds System is a semi-open standard such that compatible camera bodies can be built by different companies.
Walter Mandler was a lens designer of Ernst Leitz Canada in Midland, Ontario. Mandler is credited with the design of more than 45 Leica lenses for the Leica rangefinder cameras and Leica SLR cameras.
The name Noctilux is used by Leica to designate their camera lenses with the widest maximum aperture. Lenses with that name have been in production since 1966. So far all Noctilux lenses have been made for the Leica M mount.
The Micro Four Thirds system is a standard released by Olympus and Panasonic in 2008, for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses. Camera bodies are available from Blackmagic, DJI, JVC, Kodak, Olympus, Panasonic, Sharp, and Xiaomi. MFT lenses are produced by Cosina Voigtländer, DJI, Kowa, Kodak, Mitakon, Olympus, Panasonic, Samyang, Sharp, Sigma, SLR Magic, Tamron, Tokina, TTArtisan, Veydra, Xiaomi, Laowa, Yongnuo, Zonlai, Lensbaby, Venus Optics and 7artisans amongst others.

The Panasonic Lumix G 14mmf/2.5 lens is a pancake-style prime lens for Micro Four Thirds system cameras. In the Micro Four Thirds format, it is moderately wide. As of its late-2010 release, it is claimed by Panasonic to be the lightest interchangeable digital-camera lens. It is the prime-lens option available with the Panasonic GF2 and GF3, and available separately.

Beside the Leica S-System, the Leica SL-System is the 2nd professional camera system in the company's product portfolio.
Nocticron is the brand name of Leica lenses with an extreme speed of f/1.2. Because of the large aperture size and its image stabilisation system it is possible to take images with relatively short exposure time especially in available light situations. Together with the high number of nine diaphragm blades the lens creates a strong and pleasant bokeh.
The Panasonic Leica D Vario-Elmar 14-150mm F3.5-5.6 Asph Mega OIS is an interchangeable camera lens announced by Panasonic on March 7, 2007. Since it has been released, it is only produced in small qualities, this makes this product quite special. It features the Four Third Systems to assure its compatibility with different camera models.
