In the digital age, these lenses allow one security camera to monitor a wide swath of property without moving, and automakers employ them as tiny backup cameras to help drivers stay safer on the road. Some of the earliest fisheyes, for example, were built by astronomers to capture images of the starry night sky. This offers fun artistic avenues to explore, but it's also very useful. The farther they are from center, the greater the curved distortion. The tradeoff is distinct: Straight lines anywhere but dead center in the fisheye image appear to curve. īut while wide-angle rectilinear lenses can capture angles of view approaching 100 degrees, fisheye lenses can stretch that to 180 degrees - impossible to do without the light-bending science they employ. The edge of the image is stretched far to the left, right, top or bottom of the center of the captured scene. Short focal lengths allow wide-angle lenses to capture a wide angle of view. Wide-angle lenses have short focal lengths, which is the distance, when a lens is focused on the farthest point possible, between the optical center of the lens surface - that is, the point in the lens, often at its center, where there is no distortion of light passing through it - and the film or sensor that receives the image. This renders straight lines as they appear in real life, wherever they are in the scene. Which instruction are you following? (Is it our paper instruction manual, online documentation, or video tutorial? A link will Help.Most of these lenses have a rectilinear design: Light entering the lens travels in a nearly straight path to the film or sensor (though all lenses are slightly curved).Which Platform are you using the product(s) on?

OEM-ready: Unlike C/CS mount lenses, M12 lenses are highly customizable in regards to product designs.Project-centric: Different projects lead to different lens requirements, you need lenses with certain FoVs for specific needs as the notion of one-lens-fits-all gets impractical from time to time.Cost-effective: You get more options with the equivalent amount of money.Lightweight: It’s tiny and takes less space than the official lenses.Why S-mount lenses are ideal for the RPi High Quality Camera: It’s now much easier for you to get the best lens you’ll need, and we will keep the lens list growing in the near future. In order to meet the new demands of the lens to work with Raspberry Pi High Quality Camera, Arducam selected and tested a wide range of M12 mount lenses from long focus to fisheye for shooting on your Rpi HQ cameras.
