Field Of View Fisheye Lens
The horizontal and vertical sides of the image are less than 180 degrees typically around 150 degrees horizontal and 100 degrees vertical. This chart represents the angle and field of view calculations for cameras with 13 lenses.

I check what is in the field of view.
Field of view fisheye lens. The short version is at the same focal length the mm number a fisheye lens should offer roughly the same field of view as the same focal length from a traditional wide-angle lens. If I want to change the view I zoom with my feet to get the photo I want. A 16mm fisheye gives a full 180 horizontal field of view.
Fisheye lenses typical focal lengths are between 8 mm and 10 mm for circular images and 1516 mm for full-frame images. A full-frame fisheye lens only captures a 180-degree field of view along its diagonal. Note that many online lens calculators produce inaccurate angle measures for these focal lengths.
In the 1970s Nikon produced a limited number of Nikkor 13mm f56 circular fisheye lenses that captured 220 fields of view which often included the hands feet andor tripod of the person taking the picture. Well my example wasnt full frame either. The lens in question is a MFT 180 fish-eye not a full frame lens.
The field of view is dependent upon the focal length of the lens the image sensor size the lens distortion and the lens image circle. The horizontal and vertical sides of the image are less than 180 degrees typically around 150 degrees horizontal and 100 degrees vertical. 1 36x24mm 35mm film frameFX sensor size - Field of View Crop Factor 1 2 236x157mm APS-CDX sensor size - Crop factor 15.
The calculator utilizes an advanced distortion model to calculate the FoV of wide angle and fisheye lenses. Also most 14 cameras produce a significantly narrower field of view with the same focal length lens. You can use the Voigtlander 12mm and 15mm lenses on your 5D but its a mither and reaps few tangible rewards.
Up to 180 and beyond. Fisheye lens has a wider FOV than 140. Field-of-views aside the key differences between the two types of imagery is that while the 10mm Voigtländer hyper-wide lens has a field-of-view of only 130 it displays far less distortion compared to the funhouse mirror-like photographs you capture with fisheye lenses.
Unfortunately no one makes a lens at that focal length so youd have to approximate with something slightly shorter or longer say a 35mm lens. This subsection summarizes a number of FOV models including fisheye lens cylindrical panoramic view omnidirectional lens and panomorph lens. As you can see the rectilinear lens can never get to a 180 degree FOV no matter how large the frame size but all the fisheye lenses can.
Then there are the fisheyes. Brad-- hide signature --I go through life shooting Snap Shots. This means that the lens manages to squeeze in more in the horizontal and vertical planes also.
This 35 MM Full-Frame lens works with Sony α cameras. Most fisheye lenses give a 180 degree field of view but the Samyang 12mm 28 lens achieves this at a wider focal length due to the stereographic projection. The angle of view of a fisheye lens is usually between 100 and 180 degrees while the focal lengths depend on the film format they are designed for.
Lenses are often referred to by terms that express their angle of view. Wide field of view lenses for surveillance. See the above diagram stereographic is the pink curve.
Linear field of view 2 Tan Angle of view2 X Distance to Subject Common Focal Lengths and Their Corresponding FOVs Since the equation for field of view contains the sensor width which determines the crop factor of a lens this is another way to see the effect that the crop factor of a camera has on an image. Carefully de-fished it can deliver exceptionally well controlled distortion and sharp corners. The plot below shows how the field of view relates to frame size for a given focal length lens for a rectilinear lens and four types of fisheye lens.
Circular fisheye lenses capture photographs with up to 180 fields of view. Diagonally the FOV is 468 degrees. A full-frame fisheye lens only captures a 180 degree field of view along its diagonal.
Where a 50mm fixed lens has a 47-degree field of view on a full frame camera a 31mm lens has a 47-degree field of view on a 16x crop sensor camera. 16 mm F28 Fisheye lens SAL16F28 The SAL16F28 offers a full 180 angle of view on 35 mm format cameras 110 on APS-C format so you can get creative with distortion perspective and depth of field. Mass-produced fisheye lenses for photography first appeared in the early 1960s and are generally used for their unique distorted appearance.
For a 55mm lens on a APS-CDX sensor format body the field of view would thus be 240 degrees horizontally 161 degrees vertically and 287 degrees diagonally.
