Nikon lenses could be used in the F-mount and Z-mount of the Nikon camera. In addition, the Nikon F-mount lens could be transferred to the Sony-E-mount body through the transfer ring, but this was not the Nikon body interface. Read more exciting novels for free
The Nikon lens interface contacts played an important role in the communication between the camera and the lens. For example, in a Nikon camera, if there was a problem with the lens interface contact, such as the Nikon Z6ii using too much force when cleaning the camera bayonet contact, the contact might be damaged, resulting in the golden contact not being able to bounce up, causing the signal to not be able to communicate with the lens, and the body would not be able to recognize the lens. Nikon lenses with different mounts were also related to contacts in terms of functions. Nikon lenses had F mount and Z mount. F-mount lens series such as AF-S series had CPU contacts, AF-P series also had CPU contacts, etc. These contacts were related to the lens 'autofocus, anti-shake function, and compatibility with the camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon lenses mainly had the lens mount, which was Canon's full-frame single-lens reflex camera mount, as well as the lens mount, such as the ESF-S mount, the ESF-M mount, and the lens mount. Nikon lenses mainly had the lens mount, such as the F-mount, and the Z-mount. Their bayonet types were different, and their size, the distance between the two sides, the number and location of electronic contacts, and other parameters were also different. These differences determined the compatibility between the lens and the body, as well as the realization of functions. For example, Canon's RF-mount and Nikon's Z-mount were large-caliber mounts, but there were still differences in specific size and other characteristics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The lens mount of a Nikon single-lens reflex camera was an F-mount. From the early film DSLR to the recent digital DSLR, they all used F-mount. In terms of F-mount lenses, due to the different mechanical/electronic transmission methods of aperture adjustment, aperture information transmission, focal length information transmission, and autofocus, there were many types of single-lens reflex lenses. For example, manual non-CPU lenses included STAR lenses, AI lenses, AIS lenses, etc. According to the type of aperture adjustment, there were D-type lenses with manual aperture rings, G-type lenses without manual aperture rings, E-type lenses with electromagnetic apertures, etc. The F-mount lens was divided into two types: the FX-mount lens (suitable for all Nikon single-lens reflex cameras, similar to Canon's EF-mount lens) and the DX-mount lens (suitable for Nikon APS-C format cameras, similar to Canon's EF-mount lens). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon lenses and Nikon lenses were well-known brands in the field of camera lenses. In terms of Nikon lenses, the new Z-mount lenses were generally of high quality, such as holo-field compatibility and excellent corner resolution. The F-mount was limited by the caliber and the distance between the two sides, while the Z-mount had a great improvement in this aspect, especially in the wide-angle to mid-focal length section. Canon lenses, such as the RF28 - 70mm F2.8 lens, had a constant large aperture of F2.8. It was portable, and the image quality was average, even a little beyond the positioning of the silver ring lens. It also had anti-shake function. However, its price was sometimes affected by marketing routines. For example, during the 11/11 period, the price of Canon RF28 - 70mm was higher than the recommended price on the official website and did not return to normal value. These two lenses had their own optical design features, advantages, and market positioning under different camera mount systems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The lens and camera interface was a component used to connect the lens and the camera. Suzhou Ouka optical instrument factory specialized in the production and development of a camera interface, this interface can be connected to different brands and models of lenses, so that the camera can be used normally. There are many types of industrial camera cable ports: - **USB port **: It is a commonly used port for digital cameras. It can directly output digital image signals. USB was the full name of Universal serial bus. The interface was 4-pin, including 2 power cables and 2 signal cables. There were different versions of USB. The early USB2.0 interface was convenient and widely used, but the transmission rate was slow (480Mbit/s), the communication distance was short (5m), and the band width was mostly used for image transmission (80%). The transmission required the CPU to participate in management and consumed a lot of resources, and the interface was unstable. USB3.0 added two sets of data lines on the basis of USB2.0, which were backward compatible. The transmission speed was increased to 4.8Gbit/s, and the communication distance was extended to 10m. However, the transmission distance was still relatively short. USB interface cameras were easy to use and had a wide range of ports. They were widely used in microscopes, scientific research experiments, portable equipment, and other industries. At present, USB Type Micro-B ports were the mainstream on industrial interface cameras. In the future, USB Type C ports might be popularized. - ** IMEE1394 (Firewire Interface)**: It is a high-speed serial bus. It supports hot swapping, real-time data transmission, and uses a bus structure. It is widely used in the industrial field. It has good protocol and coding methods, and the transmission speed is stable. The 1394a's maximum transmission speed was 400mps, and the 1394b's maximum transmission speed was 800mps (3.2mps was relatively rare). Its interface was divided into 4-core and 6-core. The 4-core contained two pairs of data cables, and the 6-core had a set of power cables in addition to the data cable. This interface did not require a controller and could be used for peer-to-peer transmission. The 1394a's maximum transmission distance was 4.5 meters, and the 1394b's transmission distance was usually 10 meters (100 meters, 100 Mbit/s, when the data rate was reduced). However, the interface's penetration rate was low and it had been slowly eliminated by the market. - **Camerlink interface **: A digital image signal communication interface protocol introduced by the Aia Association. It is a serial communication protocol that uses the LVVS interface standard. It was developed from the Channel Link technology, adding the transmission control signal and defined the relevant transmission standards. The protocol used the MDR - 26-pin connection or the SAR- 26-pin connection, which had high speed (up to 6400Mbps), strong anti-interference ability, and low power consumption. However, it required a separate CameraLink interface, which was not portable, expensive, and rarely used in practical applications. - ** Gige Giga-bit ether interface **: created and promoted by Aia. It is a camera interface standard developed based on the Giga-bit ether communication protocol. It is suitable for industrial imaging applications. It can transmit uncompressed video signals over the network and can use low-cost cables to transmit images over long distances. In addition, in the field of machine vision, other data transmission ports were also developed: - **CoaXPress (CXP) interface **: launched in 2008, supports high-speed imaging applications, uses 75 Omega coax cable, supports data transmission speed of up to 6.25Gbit/s per channel, and can increase the transmission rate of multiple channels. Each cable can provide up to 13W of power. It requires the "device" and "host" to support the GenICam camera programming interface. However, the cost of installing multi-channel cable components and frame clips on a single-channel coax cable increases rapidly. - **CameraLink interface **: In 2000, it was launched by Aia Association and gradually upgraded.(2.04Gbit/s)、Medium (5.44Gbit/s) and Deca/Extended (6.8Gbit/s). Base uses an ADC- 26 pin, medium/full requires a second cable to double the capacity, Deca/Extended can transmit up to 6.8Gbit/s data, and like the CXP interface, it requires an image acquisition card that is compatible with the CameralLink power supply (PoQL) standard for power supply. It lacks error correction or resend functions. The cable setup was expensive and troublesome. - **GigE Vision standard interface **: It is managed by the Aia Association and allows the use of existing low-cost ether cables, connections, switches, and other components. Copper cables can transmit image data up to 100 meters away, and more data can be transmitted through the switch and optical fiber adapters. It has the potential to create different network topologies. Each camera can be placed on the network independently through an IP address. It can be viewed, controlled, and monitored from any PC on the network. However, the maximum 115mb/s has limitations for certain applications. However, NBUSE-T technology could increase the band width within its framework. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the lens crushed the interface, the first thing to do was to check if the lens was damaged. If there is no damage inside the lens, you can consider replacing it with a new interface. For example, if the mounting tube and the lens barrel of the Pantheon 12 - 60mm/F2.8 - 4.0 lens were broken, the mounting tube, the zoom ring, and the focus ring were integrated, and they needed to be replaced together to solve the problem. During maintenance, attention should be paid to avoiding simple and unstable maintenance methods such as simple glue to avoid secondary damage to the lens, and new parts should be used. If you are not sure how to operate it or lack relevant experience, it is recommended to seek the help of professional maintenance personnel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The common electrical ports of the lens were as follows: 1. ** DC-port **: Most cameras have a 5.5*2.1 DC-plug as the power interface. 5.5 refers to the outer diameter of the power plug of 5.5mm (tolerance: 0.05mm), and 2.1 refers to the inner diameter of the plug of 2.1mm (tolerance: 0.05mm). The power plug was positive inside and negative outside, while the positive and negative poles of the camera interface were the opposite. The inside was negative and the outside was positive. The common specifications of the camera's power supply voltage were 12V and 9V. 2. ** tyrannic-c interface **: For the convenience of power supply in home IPCs (network cameras), the tyrannic-c interface, also known as the usb-c interface, was used. Its power supply specifications were 5v/1A. 3. **PoE interface **: PoE power supply is provided through the 1236 or 4578 cores of the network cable (1236 cores transmit data at the same time). The PoE interface is an ordinary network cable interface, so there is no need to provide a separate DC-interface. PoE power supply is divided into standard PoE power supply and non-standard PoE power supply. The standard PoE is in accordance with the IMEE802.3af, and the device supports 1236 and 4578 power supply methods. The non-standard PoE power supply directly provides 12V, 24V, 48V or 54V power supply parameters. Generally, the power supply and equipment are customized and cannot be used at will. Otherwise, it may cause equipment failure or instability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the lens interface broke, he could consider replacing it with a new mount as long as there was no damage inside the lens. For example, for the Pantheon 12 - 60mm/F2.8 - 4.0 lens, the bayonet fixing tube and the lens barrel had signs of being bonded and were easy to break again. In this case, new parts needed to be replaced, and the lens fixing tube was integrated with the zoom ring and the focus ring. It might need to be replaced together to solve the problem. In the case of a broken plastic lens bayonet, the broken part could be removed with a broken wire picker. The specific steps were as follows: determine the size of the part to be removed, select a suitable picker, insert the broken wire picker into the broken part, tighten it clockwise, clamp the rear bayonet of the broken wire picker with a wrench, and rotate the picker counterclockwise to remove the broken part. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Among the mentioned micro-single lens mounts, the diameter of the Sony-E mount was 46mm, the Nikon Z-mount was 55mm, and the Pantheon M4/3 mount was mainly used for Olympus mirrorless cameras. The diameter was not mentioned, but from the overall comparison, the Sony-E mount had a relatively small diameter, so the Sony-E mount was probably the smallest of these micro-single lens mounts. However, he could not rule out the possibility that there were other unmentioned micro-single-lens mounts with smaller size. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Seven Artisans had introduced the ESF-NZ mount ring, which allowed the Nikon Z series micro-camera to use Canon's ESF-mount lens. It basically supported all Canon's ESF-mount lenses and the functions supported by the lens itself. The AF-focusing function was normal. When paired with the Nikon Z series micro-camera, it could support the phase detection focusing function and video capture auto-focusing. When the camera turned on the eye-focusing function, the lens could also be controlled through this ring. The aperture supported f/1.0 to f/64. The built-in micro-USB port could update the firmwares. The ring was made of metal, weighed 104 grams, and was priced at 149 US dollars. There was also the Fringer ESF-NZ mounting ring from the Feldworld, Canon's EF-EFA mount to Nikon's Z-mount automatic mounting ring. Theoretically, it supported all relatively new EF-S/EF-S mount lenses (including subsidiary products). It supported electronic aperture control, phase focusing, and EXIF recording. Its performance was close to that of the original FTHZ mounting ring, and it supported AF-S/AF-C/AF-F (video)/MV. It supports face/eye recognition focusing (in some camera video modes, it supports smooth transition of focus and can adjust the driving speed of AF. It supports lens or body anti-shake (the two cannot work together). It comes with a disassembled tripod stand and USB port for hardware upgrade and a professional extinction design. It is priced at 1980 yuan in Jingdong Mall (can participate in full reduction and stack coupons). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
