funnels light to the image sensor and only the very center of the lens delivers light in a straight path, creating the obvious distortion of the outer edges of a photograph, seen as curves where there would ordinarily be straight lines. This is the very effect that makes these lenses so ...
What is a prime lens? A prime lens is a fixed focal length lens that doesn’t let you zoom in or out. This focal length is the distance between the point of convergence in the lens to the sensor in your camera. Prime lenses have very wide or large apertures. Apertures measure the si...

There are six types of lenses. A lens is made according to the laws of light refraction. A lens is an optical element made of transparent substances such as glass, crystal, etc. A lens is a refracting mirror with two spherical surfaces, or a transparent body with one spherical surface an...
a cinema lens will have its aperture rated by the amount of light the lens is able to gather and transmit to the sensor at a given aperture-a T-stop. The reason for this is simple-in the video and cinema world, it’s almost always more useful for a camera operator or director of ...
Spherical aberration is most pronounced when the diaphragm of the lens is wide open (maximum aperture). Stopping down the lens even by a single stop dramatically reduces spherical aberration, because aperture blades block the outer edges of spherical lenses. A clear example of this can be found ...
