Canon EOS 5DS
The Canon EOS 5DS and EOS 5DS R (known as the EOS 5Ds and EOS 5Ds R in Japan) are two closely related digital SLR cameras announced by Canon on February 6, 2015. Both are professional full-frame cameras with 50.6-megapixel sensors, the highest of any full-frame camera at the time of announcement. The only difference between the two models is that the sensor of the "R" version includes an optical filter that cancels out the effects of a standard optical low-pass filter. This distinction is roughly similar to that between Nikon's now-replaced D800 and D800E (with the E having a self-cancelling filter). Canon stated that both the 5DS and 5DS R will not replace the older EOS 5D Mark III; therefore, both the 5DS and 5DS R will have their new positions in Canon's DSLR camera lineup. At the time of announcement, estimated prices were US$3,699.00 and US$3,899.00 (EOS 5DS and EOS 5DS R), with announced date of availability, through authorized Canon retaile ...

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 ...

CompactFlash
CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994. CompactFlash became one of the most successful of the early memory card formats, surpassing Miniature Card and SmartMedia. Subsequent formats, such as MMC/ SD, various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS, are faster, but physically larger and more costly. CompactFlash's popularity is declining as CFexpress is taking over. As of 2022, both Canon and Nikon newest high end cameras, e.g. the Canon EOS R5, Canon EOS R3, and Nikon Z 9 use CFexpress cards for the higher performance required to record 8K video. Traditional CompactFlash cards use the Parallel ATA interface, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon D800
The Nikon D800 is a 36.3-megapixel professional-grade full-frame digital single-lens reflex camera produced by Nikon Corporation. It was given a Gold Award by Digital Photography Review. It was officially announced on February 7, 2012 and went on sale in late March 2012 for the suggested retail price of $2999.95 in the U.S., £2399 in the UK, and €2892 in the Eurozone. Shortly after the camera went on sale, Nikon's UK subsidiary increased the price of the D800 in that market by £200 to £2599, saying that the original price was due to an "internal systems error". However, Nikon honored the original price for all pre-orders placed before March 24, and added that no price changes would be made in other markets. The successor is the Nikon D810 – announced June 26, 2014. Features *36.8 (36.3 effective) megapixel full-frame (35.9 mm × 24 mm) sensor with ISO 100–6400 (ISO 50–25600 boost) * Nikon Expeed 3 image processor *91,000 pixel RGB metering sensor with Ad ...

(, ; ), also known just as Nikon, is a Japanese multinational corporation headquartered in Tokyo, Japan, specializing in optics and imaging products. The companies held by Nikon form the Nikon Group. Nikon's products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer. The company is the eighth-largest chip equipment maker as reported in 2017. Also, it has diversified into new areas like 3D printing and regenerative medicine to compensate for the shrinking digital camera market. Among Nikon's many notable product lines are Nikkor imaging lenses (for F-mount cameras, large format photography, photographic enlargers, and other applications), the Nikon F-series of 35 mm film SLR cameras, the Nikon D-series of digital SLR cameras, the Nikon Z-series of digital mi ...

Anti-aliasing Filter
An anti-aliasing filter (AAF) is a filter used before a signal sampler to restrict the bandwidth of a signal to satisfy the Nyquist–Shannon sampling theorem over the band of interest. Since the theorem states that unambiguous reconstruction of the signal from its samples is possible when the power of frequencies above the Nyquist frequency is zero, a brick wall filter is an idealized but impractical AAF. A practical AAF makes a trade off between reduced bandwidth and increased aliasing. A practical anti-aliasing filter will typically permit some aliasing to occur or attenuate or otherwise distort some in-band frequencies close to the Nyquist limit. For this reason, many practical systems sample higher than would be theoretically required by a perfect AAF in order to ensure that all frequencies of interest can be reconstructed, a practice called oversampling. Optical applications The Pentax K-3 from Ricoh introduced a unique sensor-based anti-aliasing filter. The filter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Sensor
An image sensor or imager is a sensor that detects and conveys information used to make an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, camera phones, optical mouse devices, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, electronic and digital imaging tends to replace chemical and analog imaging. The two main types of electronic image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor). Both CCD and CMOS sensors are based on metal–oxide–semiconductor (MOS) technology, with CCDs based on MOS capacitors and CMOS sensors based on M ...

Canon EOS 5D Mark III
The Canon EOS 5D Mark III is a professional-grade 22.3 megapixels full-frame digital single-lens reflex (DSLR) camera made by Canon. Succeeding the EOS 5D Mark II, the Mark III was announced on 2 March 2012. This date coincided with the 25th anniversary of the announcement of the first camera in the EOS line, the EOS 650, and was also Canon's 75th anniversary. The Mark III went on sale later in March with a retail price of $3,499 in the US, £2999 in the UK, and €3569 in the Eurozone. On 25 August 2016, Canon announced the camera's successor, the Canon EOS 5D Mark IV.

DIGIC 6
Digital Imaging Integrated Circuit (often styled as "DiG!C") is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a version number suffix. Currently, DIGIC is implemented as an application-specific integrated circuit (ASIC) designed to perform high speed signal processing as well as the control operations in the product in which it has been incorporated. Over its numerous generations, DIGIC has evolved from a system involving a number of discrete integrated circuits to a single chip system, many of which are based around the ARM instruction set. Custom firmware for these units has been developed to add features to the cameras. DIGIC in Cameras Original DIGIC The original DIGIC was used on the PowerShot G3 (Sep 2002), Canon S1 IS (Mar 2004), A520 (Mar 2005), and other came ...
