Fisheye lens
A fisheye lens was a lens with a focal length of about 6 - 16mm and a viewing angle close to or equal to 180°. It was a type of ultra-wide-angle lens. Its front lens was shaped like a parabola and protruded to the front of the lens. It had a wide angle of view and was similar to the eyes of a fish, hence its name. It usually consists of a front group of imaging lenses and a rear group of correction lenses, and is divided into two types of half-frame fisheye lenses and full-frame fisheye lenses. It was first used in photography to create artistic photos with a large field of view and large distortion. It was also widely used in fields that required wide-angle imaging, such as surveillance, dome imaging, aerospace cameras, and other industrial, medical, and scientific research fields. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fisheye lens drone
Fisheye lenses could be used in drones. For example, LAOWa has a 4mm F2.8 210° circular fun fisheye lens that can be used for drone aerial photography, suitable for a variety of camera mounts such as Fuji micro-single X mount, Sony micro-single E mount, etc.; Chuangan Optoelectronics developed a 0.7mm, F2.8, 210° M8 fisheye lens, which was successfully applied to the visual obstacle avoidance of drones. By installing this lens in four directions, it could achieve no dead angle image acquisition. The image could be processed to give movement instructions to bypass obstacles. It could cruise automatically with the satellite positioning system and cooperate with the ground station for image big data analysis. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Wesley fisheye lens
It was mentioned in the reference materials that an 8mm fisheye lens called "Wesley" was used for photography. It was used in conjunction with the Fuji X-T10, with an aperture of f/2.8, a single exposure of 1 minute. In addition, a 7.5mm fisheye lens named "Wesley" was mentioned for fisheye photography. However, there was no more detailed technical parameters or special design information about the Wesley fisheye lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Like a fisheye lens
There were super wide-angle lenses that were similar to fisheye lenses. Fisheye lens was a type of ultra-wide-angle lens. Its focal length was about 6 - 16mm and the angle of view was close to or equal to 180°. The front lens was a parabolic shape that protruded to the front of the lens, creating artistic photos with a large field of view and large distortion. It was widely used in surveillance, dome imaging, aerospace cameras and other fields that required wide-angle imaging. It was mostly used in industrial, medical, scientific research and other fields. The ultra-wide angle lens also had a larger angle of view and could cover a wider scene. It was more commonly used when shooting landscapes, buildings, and other subjects that needed to show a wide sense of space, but its angle of view and distortion were usually not as extreme as the fisheye lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon single-lens reflex fisheye lens
Canon had a wide range of products in the field of fisheye lenses. In the early days of the FO era, the FO 7.5mm f/5.6 S.S.C. circular fisheye lens and the FO 15mm f/2.8 S.S.C. diagonal fisheye lens were introduced. Among them, the FO 15mm f/2.8 S.S.C. was the fisheye lens with the largest aperture at that time. At the beginning of the launch, the EF15mm f/2.8 fisheye lens was introduced. It used an AFD arc motor to drive the focus. The straightness of the central part of the image and the distortion around it caused an extremely exaggerated image effect. This lens lasted for 23 years. According to the current DSLR image quality requirements, it was insufficient. Moreover, the EOS system lacked a circular fisheye lens at that time. In 2024, Sima released a 15mm F1.4 diagonal fisheye lens. In addition, Canon once launched the RF5.2mm F2.8L Dual FISHEYE full-frame radio frequency lens in the 3D VR system for 3D VR image production on October 12,2021. It uses a double-fisheye lens layout and can shoot 3D images with a baseline disparity of 60mm between the two lenses. The recommended retail price is 14399 yuan. At the "CP+2024" camera exhibition, which opened on February 22, 2024 local time, Canon showed off its VR lens series. One of them was a lens that combined two fisheye lenses. Canon planned to launch this lens as early as this year. The price was less than 100,000 yen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon fisheye lens photo
The photos taken with Canon's fisheye lens had a unique effect. Because the fisheye lens had a 180-degree angle of view, it was as wide as a fisheye. The angle of view it captured was extremely wide, but it would be distorted according to the angle of the shot. For example, Canon's 8 - 15mm lens could enliven small animals in the wilderness and obtain sharp images. Canon's fisheye lens also had a miniaturized lens body and adopted a waterproof and dust-proof structure. It could be used safely in harsh shooting environments such as light snow, snow, and ice. In terms of portrait shooting, using a fisheye lens to shoot portraits on the street might be challenging. There might be a overturning situation, but it could also take photos with a sense of atmosphere. In general, the photos taken with Canon fisheye lenses could show unique visual effects, but the super wide angle was not very useful in non-professional photography scenes because it was easy to capture things and scenes that were not needed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The phone is connected to the fisheye lens
At present, there were two main ways to connect a phone to a fisheye lens: one was to install an external lens directly on the phone lens, which could be fixed to the phone lens according to the instructions; the other was to use the built-in special effects of the phone APP, which required the corresponding fisheye effect to be turned on in the camera app. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fisheye lens stitching software
The following are some software that can be used for fisheye lens stitching: 1. <strong></strong>The software includes image stitching and blending functions, which can create ordinary, cylindrical, and spherical panoramic photos. It also provides a visual interface to achieve image stitching, thereby creating high-quality panoramic images. It has a detail viewer (you can switch between zooming and perspective), four different blending modes (in display mode, the seams are highlighted with red lines to find potential routes or blending errors), and the professional version of the MTGui has a mask function (you can hide a part of the final blended image). 2. Jian e panoramic: A VR panoramic online synthesis software. It adhered to the purpose of helping designers and improving the display effect. It provided a one-stop solution for 720-degree synthesis of panoramic views, panoramic plan reports, and other forms. It was compatible with PC, mobile, and tablet for work display. 3. 720Cloud: It is dedicated to the efficient creation of high-quality products such as VR panoramic/XR/3D/digital human and other meta-universe content, helping the brand/marketing/service digital upgrade, focusing on the learning, production, community sharing, copyright, commercial application and other processes of panoramic creation, providing services for the growth of creators and the excavation of content value. 4.
