How to add a Fisheye camera in Cinema 4D?
Another key feature added to the V4 release of Corona Renderer for Cinema 4D was the fisheye lens. A fisheye lens is an ultra-wide lens used in photography and cinema. Such lenses are used to capture an extremely wide field of view (FOV), making it a perfect choice when shooting space might be limited or confined.
How to set it up?
Setting up a fisheye lens in Cinema 4D is extremely simple and also fun to use. With a Corona camera in your scene, click on the camera tag and scroll to the bottom of the camera parameters. In the 'Camera Projection' section, enable 'Override' and select 'Fisheye' from the drop-down menu. Doing this will allow you to fine-tune your shot even further. In the 'Fisheye FOV' (field of view) setting, input the desired focal range you plan to cover. By default, it is set to 180 deg and has a maximum FOV of 360 deg.

The type of Fisheye format you will choose will depend on the final look you are after. We offer you the following formats: Circular, Cropped circle, Full-frame, and Manual. You also have the option of choosing how the image will be mapped.
These range from:
- Equidistant: Maintains angular distances. Practical for angle measurement (e.g., star maps).
- Equisolid Angle: Maintains surface relations. Every pixel subtends an equal solid angle or an equal area on the unit sphere.
- Orthographic: Maintains planar illuminance. Looks like an orb with the surroundings, lying on < max. 180° aperture angle. Highly distorted near the edge of the image, but the image is less compressed in the center.
- Stereographic: Maintains angles. This mapping would be ideal for photographers because it doesn't compress marginal objects as much.
DOF (Depth of field) is disabled when using the fisheye camera.
