Pentax K-500
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 ...

Digital Single-lens Reflex Camera
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 ...

Nikon D5300
The Nikon D5300 is an F-mount DSLR with a carbon-fiber-reinforced polymer body and other new technologies, announced by Nikon on October 17, 2013. It is a mid-range camera with a crop sensor and requires a minimum camera 8.3 raw plugin for Photoshop to process its .NEF files. It features the Expeed 4 processor and is the company's first DSLR with built-in Wi-Fi and GPS. It shares the same 24-megapixel image sensor as its D5200 predecessor, but without an anti-aliasing (AA) filter, equal to the Nikon D7100. MSRP for the body is $800, and $1,400 with an 18-140mm f/3.5-5.6 kit lens. The camera replaces the D5200 and is replaced by the Nikon D5500.

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] |
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 ...

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] |

Canon EOS 700D
The Canon EOS 700D, known as the Kiss X7i in Japan or as the Rebel T5i in the Americas, is an 18.0 megapixel digital single-lens reflex camera made by Canon. It was announced on March 21, 2013 with a suggested retail price of US$849. As a part of the Canon EOS three-digit/Rebel digital line, it is the successor to the EOS 650D/Kiss X6i/Rebel T4i and is the predecessor of both the EOS 750D/Kiss X8i/Rebel T6i and EOS 760D/EOS 8000D/Rebel T6s. Features The 700D has a feature set almost identical to that of the older 650D. According to photographer and technology writer Gordon Laing,It's fair to say that not a great deal has changed between the T5i / 700D and its predecessor. Indeed they're identical other than three changes: a new mode dial which can rotate through 360 degrees and keep turning, previews of Creative Filters in Live View, and a new external coating inherited from mid-range models like the 60D to provide a more durable finish. The 700D, however, was introduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pentax K Mount
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras. Mounts The Pentax K-mount has undergone a number of evolutions over the years as new functionality has been added. In general, the term K-mount may refer to the original K-mount, or to all its variations. Originally designed by Zeiss for an alliance with Pentax, it was intended to be a common lens mount for a proposed series of cameras and lenses. However, the plan failed to work out and the two firms parted company amicably, but Pentax retained the lens mount and at least one Zeiss lens design for its own use. K-mount The original K-mount is a simple bayonet con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
