About This Product
With this lens, you can change the projection method by replacing only the front group. As we receive many inquiries about the projection method for fisheye lenses, we have created a lens that will explain the projection method below and allow you to see the difference in real shots.
■Orthographic projection
It is an image that is the projection of a figure on a hemisphere onto a plane. A feature of this projection method is that there is no reduction in peripheral illumination (brightness is uniform between the center and periphery of the screen).
■Equidistant projection
As you can see from the diagram, equidistant means that the pitches of the concentric circles are equally spaced.
■Stereoscopic projection
In stereoscopic projection, peripheral images are magnified four times compared to the central image. This projection method is similar to human vision, and can be said to be a psychological spatial image in which the sun and moon appear larger as they approach the horizon. Also, as you can see from the figure, in other projection methods the image is deformed as it goes to sy, but in this projection method it is not deformed.
■Equisolid angle projection
A projection in which the area of the image is proportional to the solid angle. In other words, since the solid angle can be determined from the area of the image, it is used for measuring cloud cover and obtaining position information for robots, etc.
