The jollystar 37mm 0.43x HD Fisheye Converter Lens uses multi-coated, low-dispersion glass to produce crisp, high-definition video images. Great for dramatic effects and very wide fields of view–think sports, think dream sequences, think HAL-9000 computers–this fisheye converter screws onto the front of your existing camcorder lens and bends a 180° view into a peephole-style circle. Since this is a conversion lens, you can use it through your camera’s full zoom range.
Many planetariums now use fisheye projection lenses to project the night sky or other digital content onto the interior of a dome.
Flight simulators and visual combat simulators use fisheye projection lenses in order to create an immersive environment for pilots, air traffic controllers, or military personnel to train in.
Similarly, the IMAX Dome (previously 'OMNIMAX') motion-picture format involves photography through a circular fisheye lens, and projection through the same onto a hemispherical screen.
Scientists and resource managers (e.g., biologists, foresters, and meteorologists) use fisheye lenses for hemispherical photography to calculate plant canopy indices and near-ground solar radiation. Applications include evaluation of forest health, characterization of monarch butterfly winter roosting sites, and management of vineyards.
Astronomers use fisheye lenses to capture cloud cover and light pollution data.
Photographers and videographers use fisheye lenses so they can get the camera as close as possible for action shots whilst also capturing context, for example in skateboarding to focus on the board and still retain an image of the skater.
The first music video to be shot completely with fisheye lens was for the Beastie Boys song "Shake Your Rump" in 1989.
In Computer Graphics, circular fisheye images can be used to create environment map from physical world. One complete 180-degree wide angle fisheye image will fit to half of cubic mapping space if proper algorithm applies on. Environment maps can be used to render 3D object and virtual panoramic scene.

- Q:SLR camera lens 14mm, 16mm, 18mm, the three focal length of the viewing angle were how many degrees
- You ask is not clear 'full and non-full vision is not the same' and what you ask what is the visual? Horizontal 'vertical or diagonal? Such as 14 on the full level of visual 104, the vertical is 81, the level is 114 in the non-full vision will shrink 'so you have to explain what you are on the camera
- Q:What are the meanings of the parameters on the camera lens?
- What are the meanings of the parameters on the camera lens?
SLR camera lens is a lens, its parameters are mainly two:
Caliber (aperture) the bigger the better, the bigger the more expensive.
Focal length (zoom range) The larger the zoom range, the more convenient it is to use, but the larger the zoom range is, the greater the resolution is.
- Q:SLR lens magnification how to see?
How to see the magnification of the optical zoom from the digital camera body
★ We can calculate the magnification of the optical zoom from the zoom range (focal length) of the lens. For example: Sony Cybershot DSC-F828 digital camera lens, clearly marked "7.1 - 51", which means the zoom range (focal length) from 7.1 mm to 51 mm. Then you can calculate the optical zoom multiplier of 51 ÷ 7.1 ≈ 7.
★ Many digital camera body or lens will directly identify the optical zoom multiple, such as Sony Cybershot DSC-F828 digital camera at the top of the fuselage, clearly marked "7x Optical Zoom" (see Figure 1).
Today's digital camera optical zoom multiples of 2 times -5 times, you can 10 meters away from the object closer to 5-3 meters near; there are some digital cameras have 10 times the optical zoom effect. Home camcorder optical zoom factor of 10 times to 22 times, can be more clearly photographed 70 meters away things. Use the magnification mirror to increase the optical zoom factor of the camcorder. If the optical zoom factor is not enough, we can add a magnification lens in front of the lens, the calculation method is like this, a 2 times the teleconverter, set in a 4x optical zoom digital camera, then this digital The optical zoom factor of the camera is doubled, doubled, 6 times and 8 times from the original 1x, 2x, 3x, 4x, multiplied by the magnification of the teleconverter and the optical zoom multiplier.
- Q:SLR camera lens focal length problem
- Suggestions: First, there is a Dragon 18--270 lens, the basic section of the focal lengths are included, so as long as not a professional player, the basic acceptable. At present, Nikon has a concept, 18 - 300 soon to come out. But the price may be very expensive. If you want to shoot better (this is a person who took the camera are longing for), and not bad money, then you can consider the Canon's red circle, but it is generally three heads to include 18-300 focal lengths
- Q:Camera lens has a lot of fingerprints how to do?
- And imaging effects will be greatly reduced Note: Some stains such as fingerprints dry rub is not rub off, really erase the coating will be finished, you must use a special lens water !!!!!!!! There is the lens Can not clean the rub, can not rub the rub, the physical contact with the lens coating are damaged, can also use the lens paper, suede, resin glasses for the glasses cloth once the lens is damaged Can not be remedied, the only way is to change the lens.
- Q:24-70 What does the lens mean?
- 24-70 lens means the shortest focal length of 24mm, up to 70mm zoom range.
Scope of application:
If it is full frame body, 24-70mm lens is more suitable for shooting scenery, portrait scenery, life scenes, drama.
24-70 wide-angle end of the lens is suitable for shooting buildings, characters, but the characters will be subject to change, 70mm tail shot portrait is not big enough.
- Q:Camera lens fell down to the camera on the demolition of how to do?
- Hope LZ lens is plastic bayonet, so the camera bayonet should be no serious
This situation can only repair, and if you can see the traces of the fall, is certainly to pay for
- Q:Different brands of SLR camera lens can match each other
- But because of SONY's influence in the industry, Sigma, Tenglong, Tuli three plants will provide a basic lens mount lens
With the words of nothing good or bad, of course, on the rich ZA.
SONY deputy factory glasses less, the original set up, but now does not set up, especially Photokina on the horse issued a 5,6 new a bayonet lens and zoom lens and SONY dedicated flash.
- Q:Camera lens out fixed and retracted, can not open what can not take pictures of what ah?
- Is what brand, I use the Canon, you slowly click on the click, if it is Canon that brand, the lens has such a problem, I have this card master N times, let me throw the bed, throw All right.
- Q:Camera lens 18mm a 55mm; 55mm a 230mm what it means
- Zoom range.
18mm for the smallest coke, you can take a wide range of photos.
230mm for the most telephoto, can be telephoto, like a telescope.
