360-degree videos are also known as immersive videos where a view in every direction is recorded at the same time, shot using an omni directional camera or a collection of cameras. Multiple images are stitched together to form a 360 degree view video. During playback the viewer has control of the viewing direction like a panorama, a form of virtual reality.

A new ‘Sphere Optics’ lens has been introduced, that turns DSLR into a 360 video camera. It works as an optical attachment and hence it avoids multiple images and image stitching process.

The Sphere lens features a conventional fish eye lens revolved around a central conical mirror to capture a 360-degree horizontal field of view and a 180-degree vertical field of view.

The image circle created by the lens is constrained by the vertical pixel height of the sensor. So, the best case scenario would be to use the Sphere lens with a camera sensor in which the circle will be bounded by the shortest side of the image sensor.

It has a fixed aperture of F8 and a fixed focus of 40 inches that can be adjusted with a helicoid adapter.

The Sphere lens can be a 360 video solution that relies on any camera the user owns and doesn’t disrupt the existing workflow. It allows shooting conventional content and also adapting quickly to 360 degree video by just changing to this special lens.

The final image resolution depends entirely on your camera. The manufacturers say that users will achieve roughly 5/8th of the total resolution available on the camera when using this attachment.

With current 4K sensors, the resolutions of the image produced by this lens are quite low. But, the Sphere on a RED 8K camera can be better for significant image quality and resolution.

Originally it was designed for the system specifically for the Sony A7s2 because of its low light capability and ability to shoot 4K.

Technical Information

.

Compatible cameras: RED, Canon, Nikon, Sony, Panasonic, and virtually any video camera with detachable lenses.

Mount: Nikon F mount; adaptable to most others

Aperture: f/8 (fixed)

Focus: fixed, best focus at 40″

Format: 35mm Full Frame

Field of view: 360° horizontal x 180° vertical

Resolution: dependent on the image sensor of the camera (the entire sphere is recorded as a circle on a single sensor, so resolution is based on the smallest dimension of the sensor)

Sphere also hopes to release a consumer lens for smart phones and Go Pros in the near future.
