Pentax 645Z
The Pentax 645Z is a professional medium format digital SLR camera announced by Ricoh on April 15, 2014. While it shares its sensor with the Phase One IQ250 and Hasselblad H5Dc, it retails at less than a third of the price of these (~8500 at ~27000 USD). In 2015, the 645Z won the TIPA Award for the ''Best Medium Format Camera''. The most notable improvements over its predecessor, the Pentax 645D, include much lower noise at high ISO, the ability to record video (FullHD at 30 frames per second), and a tilting rear display. It has a 27-point phase-detect autofocus system, all clustered near center of frame, and a weather sealed body. Its peak dynamic range is 14.8 EV at base ISO, compared to 12.6 EV on its 645D predecessor. Furthermore, the 645Z is compatible with the Pentax FluCard The Pentax FluCard, officially Pentax FluCard O-FC1, is a wireless accessory and memory card standard for Pentax cameras. As a memory card, it provides 16 GB of space and is specified as SDHC C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems His ...

Medium Format
Medium format has traditionally referred to a film format in photography and the related cameras and equipment that use film. Nowadays, the term applies to film and digital cameras that record images on media larger than the used in 35 mm photography (though not including 127 sizes), but smaller than (which is considered large format photography). In digital photography, medium format refers either to cameras adapted from medium-format film photography uses or to cameras making use of sensors larger than that of a 35 mm film frame. Some of the benefits of using medium-format digital cameras include higher resolution sensors, better low-light capabilities compared to a traditional 35mm DSLR, and a wider dynamic range. Characteristics Medium-format cameras made since the 1950s are generally less automated than smaller cameras made at the same time. For example, autofocus became available in consumer 35 mm cameras in 1977, but did not reach medium format until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hasselblad H5Dc
Victor Hasselblad AB is a Swedish manufacturer of medium format cameras, photographic equipment and image scanners based in Gothenburg, Sweden. The company originally became known for its classic analog medium-format cameras that used a waist-level viewfinder. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when the first humans landed on the Moon. Almost all of the still photographs taken during these missions used modified Hasselblad cameras. In 2016, Hasselblad introduced the world's first digital compact mirrorless medium-format camera, the X1D-50c, changing the portability of medium-format photography. Hasselblad produces about 10,000 cameras a year from a small three-storey building. Company history The company was established in 1841 in Gothenburg, Sweden, by Fritz Wiktor Hasselblad, as a trading company, F. W. Hasselblad and Co. The founder's son, Arvid Viktor Hasselblad, was interested in photography and started the phot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pentax 645D
The Pentax 645D is a medium format digital SLR camera announced by Pentax on March 10, 2010. Unlike other medium-format DSLRs, which accept digital camera backs of different resolutions or even manufacturers, the 645D has a fixed-back design similar to smaller full-frame and APS-C Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 31.15 mm field d ... DSLRs. The fixed back allows the 645D to be fully weather-sealed. Awards The 645D was awarded the Camera of the Year award at the Camera Grand Prix Japan 2011.

FullHD
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 projectors, ...
