How to achieve a fisheye lens
Fisheye lenses achieve special effects by using very short focal lengths and large curvatures. It usually consists of a number of lenses with a large curvature. This design allows light to enter from various angles and be projected onto the negative photo or image sensor, thereby achieving a special imaging effect. Read more exciting novels for free
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>
Single lens reflex fisheye lens tripod
In photography, a single-lens reflex, a fisheye lens, and a tripod were all important pieces of equipment. ** 1. DSLR camera ** A single-lens reflex camera was a traditional and commonly used photographic equipment. It had the feature of an interchangeable lens, which allowed it to adapt to different shooting scenes and needs. ** 2. Fisheye lens ** 1. ** Specialties ** - The fisheye lens had a very wide angle of view and could accommodate more image content. It was very useful when taking panoramic shots or when it was necessary to show grand scenes (such as landscapes, large buildings, etc.), which could greatly speed up panoramic shots. - Fish-eye lenses were divided into full-frame and half-frame lenses. The lenses of different frames needed to be matched with the camera of the corresponding frame. For example, a full-frame camera could be matched with a full-frame Canon 8 - 15mm full-frame fisheye lens with an EF-mount; a half-frame camera could be matched with a Sanyang SAMYANG EF-mount 8-mm half-frame fisheye lens from the sub-factory. - The difference in lens prices was large. Canon and Nikon's original fisheye lenses might cost tens of thousands, while the 8mm fisheye lens of SAMYANG was relatively more cost-effective. 2. ** On a single-lens reflex camera ** - The single-lens reflex camera could achieve special shooting effects by changing the matching fisheye lens. When the fisheye lens was installed, the camera could take photos or videos with a strong visual impact and obvious bending and distortion at the edge of the picture, bringing a unique artistic expression to photography. ** Tripod ** 1. ** Type and characteristics ** - There were many types of tripods to choose from on the market, such as some tripod products from Fotopro, including the M4C desktop tripod (suitable for micro single-lens reflex camera photography scenery, climbing stairs, macro, etc., small and portable), the M - 4C Pro carbon fiber tripod (camera climbing stairs small and portable, with dual panoramic head, suitable for micro single-lens reflex camera tripod small dual panoramic head macro photography), etc. There were also Manfrotto related products, such as the 405 single-lens reflex tripod gear head (suitable for fine-tuning macro panoramic, made of aluminum alloy, used for still life/architectural gear three-dimensional three-dimensional head photography stability). - Different tripods had different load bearing, height, and maneuverability. For example, some tripods had a height of more than 100 centimeters, a stable load of 10 kilograms, and a sturdy material. Even in slanted terrain or windy environments, they could stably set up the camera. They could also be used to switch between vertical and horizontal shots through the central axis. They were equipped with a 360-degree rotating head to adjust the shooting angle. They might also have a retro hand-cranked central axis, a foldable portable frame, a self-contained Bluetooth selfie, and other functions. 2. ** Cooperate with DSLR and Fisheye lenses ** - When shooting with a fisheye lens and a single-lens reflex camera, the tripod provided a stable support. Since the fisheye lens may require a long exposure time (such as taking a panoramic shot in a low-light environment) or precise composition (to make full use of its wide viewing angle), the tripod can avoid shaking due to hand-held shooting, ensuring the clarity and accuracy of the shot. Especially in scenes that required high precision such as VR panoramic shots, a stable tripod was an indispensable equipment. <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>
The fisheye lens forms a circle
The fisheye lens had two modes of imaging, one of which was circular imaging. This was because the fisheye lens used a very short focal length and a lens with a large curvature. This special optical structure allowed light to enter from various angles and project on the photo film or image sensor, resulting in special imaging effects including circular imaging. Moreover, regardless of the imaging mode (full image or circular imaging), the image taken with the fisheye lens had a strong distortion and strong perspective convergence, which was often used as a special effect lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fisheye lens aerial photography
Fisheye lenses had many advantages in aerial photography. Fish-eye lenses were super wide-angle lenses. Generally, when the angle of view reached 180 degrees, it was called a fish-eye lens. When it came to aerial photography, its extraordinary effect was first shown in its wide range of view, which created the conditions for close-up shots of large-scale scenes. For example, when shooting a panoramic image, a 360-degree panoramic image was shot with a fisheye lens, and only a few shots were needed. Using a multi-million-pel digital single-lens reflex camera, one could easily import the image into the panoramic mosaic software to easily generate a 360-degree high-resolution panoramic view. Moreover, the fisheye lens had a long depth of field, which was good for expressing the long depth of field effect of the photo. There were a variety of fisheye lenses suitable for aerial photography to choose from. For example, the 4mm F2.8 Fisheye fisheye lens launched by 7Artisans was suitable for APS-C format mirrorless cameras. It weighed only 201g and was extremely light and portable. It could be used with drone aerial photography to reduce the load on the drone while ensuring the image quality and improving the endurance performance. The equivalent focal length was 6mm, with a 225-degree diagonal. The internal structure was composed of eight groups of 10 optical structures, and the closest focusing distance was 8.5cm. Even if you focus manually, you can easily get a long depth of field. The 7 aperture blades are designed without a segment, which can adjust the aperture for precise exposure. There are Canon ESOS-M, Fujifilm X, Micro4/3 and SonyE mount versions. The 4mm F2.8 fisheye lens of LAOWa had a variety of bayonet versions. It could be used for drone aerial photography. Its angle of view was 210° wide, and it could be used for 720VR panoramic photography. The 3.5mmF2.8 220° circular fun fisheye lens of MEKO was suitable for M4/3 mount drone aerial photography. The 3.5mmF2.8 220° circular fun fisheye lens of Neiying Meike was also suitable for M4/3 mount drone aerial photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fisheye lens for party photos
There are the following characteristics and precautions when using a fisheye lens to take a party photo: ** 1. Special traits ** 1. ** View is wide ** - The angle of view of the fisheye lens was close to or equal to 180°. It could accommodate more people and scene elements in a limited space, and was suitable for taking group photos of many people. 2. ** Special Effect ** - It would produce a serious distortion effect and bring unique visual effects to the photo. For example, it could exaggerate the expression of the person or the lines of the surrounding environment to increase the interest of the photo. ** 2. Points to note ** 1. ** Character position ** - As the camera distortion became more severe the further they moved to the side, if they did not want their faces to be pulled into a big Japanese melon, they would try to move closer to the center. 2. ** Fitness of the venue ** - This kind of shot was not suitable for large open spaces. The narrower the space, the more lines there were, and the easier it was to shoot. 3. ** Light conditions ** - Pay attention to the lighting in the party environment. If you are shooting in a low-light environment, you may need to take some special shooting techniques, such as slowing down the shutter speed (such as about 1/25s), but pay attention to the stability of the hand-held camera to prevent the photo from blurring, or use a tripod to assist in shooting. At the same time, they had to pay attention to avoid the stage lights and other strong lights that would affect the quality of the photos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
