Aspects of Camera Lenses: Equator

Understanding camera lenses can help you become more creative when shooting pictures. Digital photography made the art of photography much more interesting and intriguing. If you choose the right lens, you can take amazing pictures. However, what is the right lens? Are you aware of the different aspects of camera lenses and the optical aberrations they might have? There are a number of concepts related to image quality, such as the focal length, the aperture and so on. The equator in the camera lens is also an issue to discuss.

Camera Lens Elements and Aspects

All cameras contain lenses that consist of several different lens parts and elements. Each one of these parts and elements aims to direct and adjust the light in such a way that the recreation of the images is as accurate as possible. The main goal is to minimize the possible aberrations that occur when some parts of the image are not properly translated onto the single parts once they pass through the camera lens.

The Equator

The equatorial periphery of the lens features two ridges, corresponding to the insertion of the zonule to the posterior and anterior surface of the lens capsule. Slit image photography confirms the presence of these ridges. The equator aspect is particularly important when shooting specific types of pictures, such as astronomy pictures. For instance, if you wish to take long exposure pictures that track on the stars, ensuring that they do not trail, you should mount the camera on the equatorial mounting so that you polar align it correctly and avoid possible optical aberrations (that are more visible and noticeable when shooting astrophotos or any picture with long exposure).
