Pentax K-S1
The Pentax K-S1 is a midrange DSLR camera announced by Ricoh on August 27, 2014. It has a 20 megapixel sensor — new to the Pentax line-up — and an anti-aliasing filter simulator as previously seen in the Pentax K-3. Also adopted from the K-3 is compatibility with the Pentax FluCard, which allows wireless tethered shooting and wireless download of images from the camera. In other respects, the K-S1 inherits a fair amount from the K-30/ K-50 lineage, such as the compact, 100% coverage viewfinder, 1/6000s shutter and D-LI109 battery. A stereo microphone is also built in, to complement the 1080p at 30 frames/second video capability. The K-S1 is slightly larger than the Canon EOS 100D The Canon EOS 100D, known as the EOS Rebel SL1 in the Americas and EOS Kiss X7 in Japan, is an 18.0-megapixel digital single-lens reflex camera announced by Canon on 21 March 2013. It has been described as the "world's smallest and lightest DSLR c ..., which as of August 2014 was the smallest DSLR i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DSLR
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed. The viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor as it presents it as a direct optical view through the main camera lens, rather than showing an image through a separate secondary lens. DSLRs largely replaced film-based SLRs during the 2000s. Major camera manufacturers began to transition their product lines away from DSLR cameras to mirrorless interchangeable-lens cameras (MILC) beginning in the 2010s ...

Pentax Cameras
This article discusses the cameras – mainly 35 mm SLRs – manufactured by Ricoh Imaging Corp. and its predecessors, and . Pentax must not be confused with Pentax 6x7 or Pentax 67 which are 120 medium format 6x7cm film cameras. It covers from the first "Asahiflex" models in 1952 and their successor, the pivotal "Asahi Pentax" single-lens reflex camera, last made in 1997, to the present time known as "Pentax" first made in 1981. Background The period around 1950 marked the return of the Japanese photographic industry to the vigorous level of the early 1940s, and its emergence as a major exporter. The newly reborn industry had sold many of its cameras to the occupation forces (with hugely more disposable income than the Japanese) and they were well received. The Korean War saw a huge influx of journalists and photographers to the Far East, where they were impressed by lenses from companies such as Nikon and Canon for their Leica rangefinder cameras, and also by bodies ...

Pentax K-3
The Pentax K-3 is a 24-megapixel Pentax high-end digital single-lens reflex camera with an APS-C sensor, announced on 7 October 2013. The Pentax K-3 is the successor to both the K-5 II and K-5 IIs models, which have a 16-megapixel sensor. The K-5 II (and most other cameras of its time) had an optical low pass filter or anti-aliasing (AA) filter that can prevent the appearance of moire patterning on the captured image. This filter reduces the sharpness of the image, so Pentax also produced the K-5 IIs which omitted this filter. In the K-3, Pentax obviated the need for providing two separate models by including a selectable AA filter "simulator". This mechanism vibrates the sensor when switched on, slightly blurring the image in a way that replaces the function of the optical AA filter, providing the same benefit as the filter in the K-5 II and other cameras with an optical AA filter. When the AA simulator is disabled, the sensor records a sharper image, as in the K-5 IIs. The Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pentax K-30
The Pentax K-30 is a 16.3-megapixel Pentax digital single-lens reflex camera, announced on 21 May 2012. At its introduction, it was in the middle of Pentax's DSLR range, above the now-discontinued entry-level K-r, and below the semi-pro K-5 and successor K-5 II. Overview It has a stainless steel chassis, and unlike most DSLRs of its class, is fully weather sealed. It can shoot continuously at up to 6 frames per second with a maximum shutter speed of 1/6000th of a second. It can capture video at 1080p at either 30, 25, or 24 fps. Like all current and recent Pentax dSLRs it features in-body shake reduction, removing the need for each lens to have image stabilisation. The Pentax K mount allows use of legacy lenses dating back to the 1970s, or even earlier with an M42-mount The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentax K-50
The Pentax K-50 is a 16.3-megapixel mid-level Pentax digital single-lens reflex camera, announced on 12 June 2013. It is the direct successor to the Pentax K-30 model, both of which are weather-sealed. The main differences over the Pentax K-30 include a more traditional body design, 120 available body color combinations, higher max ISO range (up to 51 200), compatibility with Eye-Fi cards and an improved kit lens (Pentax K-30 included the DA L 18-55mm lens, while Pentax K-50 bundles a water-resistant version, the DA L 18-55mm WR, both with plastic mounts). Among APS-C mid-range DSLRs Among competing APS-C mid-range DSLRs, the Pentax K-50 has the smallest body, although it is 4 mm wider than its nearest rival, the Nikon D5300. The body is made from stainless steel and polycarbonate resin, as is the Canon EOS 700D. The Pentax K-50 has an onboard microphone but lacks the audio-in port of most comparable cameras, limiting its usefulness to videographers. Pentax is the onl ...

1080p
1080p (1920×1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the ''p'' stands for progressive scan, ''i.e.'' non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes informally referred to as 2K, these terms reflect two distinct technical standards, with differences including resolution and aspect ratio. 1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projector ...

Pentax DSLR Cameras
is a brand name used primarily by the Japanese multinational imaging and electronics company Ricoh for DSLR cameras, lenses, sport optics (including binoculars and rifle scopes), and CCTV optics. The Pentax brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses. Corporate history Early history The company was founded as Asahi Kogaku Goshi Kaisha in November 1919 by Kumao Kajiwara, at a shop in the Toshima suburb of Tokyo, and began producing spectacle lenses (which it still manufactures). In 1938 it changed its name to , and by this time it was also manufacturing camera/cine lenses. In the lead-up to World War II, Asahi Optical devoted much of its time to fulfilling military contracts for optical instruments. At the end of the war, Asahi Optical was disbanded by the occupying powers, being allowed to re-form in 1948. The company resumed its pre-war activities, manufacturi ...

Live-preview Digital Cameras
Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder. This provides a means of previewing framing and other exposure before taking the photograph. In most such cameras, the preview is generated by means of continuously and directly projecting the image formed by the lens onto the main image sensor. This in turn feeds the electronic screen with the live preview image. The electronic screen can be either a liquid crystal display (LCD) or an electronic viewfinder (EVF). Background The concept for cameras with live preview largely derives from electronic (video) TV cameras. Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism. The first digital still camera with an LCD for autogain framing live preview was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
