On Jan 9, 2012 Sigma announced its first two lenses for Micro Four Thirds, the "30mm f / 2.8 EX DN and the 19mm f / 2.8 EX DN lenses in Micro Four Thirds mounts". [58] In a press release posted on January 26, 2012, Olympus and Panasonic jointly announced that "ASTRODESIGN, Inc., Kenko Tokina Co., Ltd. and Tamron Co., Ltd. join[ed] the Micro ...
However, for the record: the first autofocus lens for a still camera was the Konishiroku Konica Hexanon 38mm f/2.8 [171] built into the Konica C35 AF (1977, Japan) 35mm point-and-shoot; the first autofocus lens for an SLR camera was the unnamed 116mm f/8 [172] built into the Polaroid SX-70 Sonar (1978, USA) instant film SLR; the first ...
Using older adapted lenses on Micro Four Thirds sometimes leads to a slight losses in image quality. This is the result of placing high resolution demands on the center crop of decade old 35mm lenses. Therefore, 100% crops from the lenses do not usually represent the same level of pixel-level sharpness as they would on their native formats.
Sharp's SmartLink technology was incorporated into the Aquos LC-15L1U-S. [2] From 2015 to 2018, Sharp-branded TVs sold in the United States were made by Chinese manufacturer Hisense. In 2019, Sharp regained its licensing and brand, buying back its assets from Hisense. Sharp-manufactured Sharp TVs have been back on the market since late 2019. [3]
In Summer of 2007, Pioneer released the Kuro line of plasma displays, that the company claims has the best black levels of any flat panel display which leads to greater contrast, and more realistic images. [25] Kuro means black in Japanese. Pioneer Cycle Sport – GPS bicycle computers and single/dual-sided crankset-based power meters. [26]
A lens may be considered a thin lens if its thickness is much less than the radii of curvature of its surfaces (d ≪ | R 1 | and d ≪ | R 2 |).. In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces.
The APO version has a red ring on the end of the lens body to distinguish it from the non-APO version of the lens, the Sigma 70-300mm F4-5.6 DG Macro. [3] This lens has 14 elements in 10 groups including two special low dispersion glass elements in the front lens group, and one in the rear lens group. [1] The non-APO version has only one such ...
Two years earlier, the lens had been introduced as a one-touch zoom in the manual-focus Minolta SR mount (as a "plain" MD lens). However, production slowed and then eventually stopped for both the AF and MD versions; its successors, the 70-210mm f / 3.5-4.5 and 70-210mm f / 4.5-5.6 had none of the qualities of the original and build and image ...
