Nikon Z 6II
The Nikon Z6II is a high-end (at the time of release) full-frame mirrorless interchangeable-lens camera (MILC) produced by Nikon and is the successor to the Nikon Z6. The camera was officially announced on October 14, 2020 alongside the Nikon Z7II, and became available for purchase on November 5. Features The most notable upgrade over the Nikon Z6 is the inclusion of a second memory card slot. The Z6II features an SD card slot and a CFexpress/XQD card slot. The camera features dual EXPEED 6 image processing engines, a first for Nikon cameras. This improves autofocus performance and enables 4K video recording at 60 fps. The frame rate for photos was increased from 12 fps to 14 fps with a larger memory buffer, but 14 fps can only be used in 12-bit RAW and single-point autofocus. The autofocus system has been vastly improved with more advanced eye detection. Lastly, in video recording, the camera can now record 4K "Ultra HD" footage at 60p in DX-crop mode. The Z6II features the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active. The IEEE 802 standards are restricted to computer networks carrying variable-size packets, unlike cell relay networks, for example, in which data is transmitted in short, uniformly sized units called cells. Isochronous signal networks, in which data is transmitted as a steady stream of octet (computing), octets, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards. The number 802 has no significance: it was simply the next number in the sequence that the IEEE used fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon Z6
The Nikon Z6 is a full-frame mirrorless interchangeable-lens camera produced by Nikon. The camera was officially announced on August 23, 2018, to be released in November. Nikon began shipping the Z6 to retailers on November 16, 2018. This was the second camera to use Nikon's new Z-mount system after the release of the 45.75 megapixel Nikon Z7 in September 2018. This more-affordable 24.5 mega-pixel full-frame model offers nearly all of the same specifications as the Z7. Aside from the lower resolution, differences include fewer phase-detection autofocus points (273 compared to 493) and an added anti-aliasing filter. The fewer mega-pixels allow for some benefits: a higher ISO equivalent, faster 12 fps (vs. 9 fps) drive speed, greater burst depth, and the ability to capture oversampled 4K video in full-frame up to 30 fps (and also in APS-C Crop, 10 MP APS-C still images can be captured) recording. Three Z-mount lenses were available by December 2018, the Nikkor Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nikon Z7
The Nikon Z7 is a 45.7 megapixel full-frame mirrorless interchangeable-lens camera produced by Nikon. The camera was officially announced on August 23, 2018, for release in September 2018. It was the first camera to use Nikon's new Z-mount system; the second model, released in November 2018, was the 24.5 megapixel Nikon Z6. Three Z-mount lenses were available by December 2018, the Nikkor Z 24-70 mm S, the 35 mm S and the 50 mm S, all three covering a full-frame (FX) image size. The F-to-Z mount adapter accessory allows for using Nikon lenses from the digital SLR series with full compatibility. In late 2018, Nikon also published a "roadmap" of lenses to be released between 2019 and 2021. A total of nine products were included in that list. The Nikon Z7 was succeeded by the Nikon Z7II in October 2020. Features * 45.7 megapixel Back-illuminated sensor (BSI) CMOS sensor. * Native ISO range of 64–25,600. * Expeed 6 image processor. * Nikon Z mount featuring a ...

Back-illuminated Sensor
Comparison of simplified back-illuminated and front-illuminated pixel cross-sections A back-illuminated (BI) sensor, also known as back-side illumination (BSI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance. The technique was used for some time in specialized roles like low-light security cameras and astronomy sensors, but was complex to build and required further refinement to become widely used. Sony was the first to reduce these problems and their costs sufficiently to introduce a 5-megapixel 1.75 μm BI CMOS sensor at general consumer prices in 2009.''Sony'', 2009 BI sensors from OmniVision Technologies have since been used in consumer electronics from other manufacturers as in the HTC EVO 4G Android smartphone, and as a major selling point for the camera in Apple's iPhone 4.''Apple'', 2010 Description A traditional, front-illuminated di ...

CFexpress
CFexpress is a standard for removable media memory card, cards by the CompactFlash Association (CFA). The standard uses the NVM Express protocol over a PCI Express, PCIe interface. 3 different form factors are available, with 1 to 4 PCI-E lanes available. History On 7 September 2016, the CompactFlash Association announced the CFexpress standard, with specifications based on the PCI Express interface and NVM Express protocol. On 18 April 2017 the CompactFlash Association published the CFexpress 1.0 specification.

Full-frame Mirrorless Interchangeable-lens Camera
A mirrorless camera (sometimes referred to as a mirrorless interchangeable-lens camera (MILC) or digital single-lens mirrorless (DSLM)) is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) and compact system camera (CSC). When compared to similar DSLRs, these cameras can be smaller, lighter, and quieter. In cameras with mirrors, light from the lens is directed to either the image sensor or the viewfinder. This is done using a mechanical movable mirror which sits behind the lens. By contrast, in a mirrorless camera, the lens always shines light onto the image sensor, and what the camera sees is displayed on a screen for the photographer. Some mirrorless cameras also s ...

Nikon Z6III
The Nikon Z6III is a mid-range full-frame mirrorless camera produced by Nikon. The camera was announced on June 17, 2024. Features Image sensor The Z6III features a 24.5-megapixel, partially stacked CMOS sensor, which enables the camera to match the 120fps burst ( DX format, 10MP only) capability of the Nikon Z8 and Z9 cameras with fully stacked CMOS sensors. Due to this, Z6III has the fastest readout speed in its class as of June 2024. Image processor The Z6III uses the EXPEED 7 image processor, which are also used in Nikon Zf, Z8, Z9, and Z50II. Video capability For videographers, the Z6III supports 6K video recording at 60 frames per second. Additionally, it offers 4K recording at 120 frames per second and Full HD at 240 frames per second. The camera includes features such as focus peaking, zebra patterns, and customizable picture profiles to aid in achieving professional-grade video quality.

Nikon Zf
The Nikon Zf is a Mirrorless camera, mirrorless interchangeable-lens camera with the Nikon Z-mount with a list price of $1999 body only, in the US. History The camera was announced on 20 September 2023 and was shipped out to customers in Japan on 27 October 2023 (others unknown). On 25 September 2023, Nikon announced that the Zf is expected for delayed delivery for some customers due to unexpected order volume. __TOC__ Features The Zf is a full-frame camera believed to use the same 24.5MP BSI-CMOS sensor used in the Nikon Z6II, as its official specifications are the same. It has a 273-point phase-detection autofocus system and can shoot up to 10 frames per second in normal mode, and 14 frames per second in expanded mode. Although it closely resembles the Nikon Zfc, which was also based on the design of Nikon's classic Nikon FM2, FM2 with almost the same internals of Nikon Z50, there are number of upgrades on the Zf, even in comparison to the Z6II on which the camera internals ...
