Lenses Standards

Updated : Saturday, March 9, 2013

At the time of SLR cameras Silver, the majority of pictures were boxes provided or used with standard 50mm optical say. Now and since the advent of digital, they are supplied with zoom lenses. Since this Actually, people have forgotten the use of standard lenses.

This type of Lenses is considered by many photographers and myself as a fixed focal length. Individuals may also consider Zooms as standard lenses. Really all depends on the focal length of these Lenses. Lenses standards are considered representatives of the Lenses that the eye sees. Its focal length and close to the diagonal of the sensitive surface of the camera. Focal length of optical standards generally ranges from 24 mm to 150 mm in most cases.

These Lenses are very pleasant to use for several reasons. A photo taken with a standard lens will look better and will capture light more important than zoom (except high-goal range) . standard These Lenses are more discreet, lighter, obviously smaller, more versatile and have a value price.

The other point is that no visual distortion or optical distortion is represented at an outlet. It may be few, but they are so tiny, it goes unnoticed. If may exist, it will be especially targets Bas-end.

With this type of so-called objective standards, a photograph taken will be easily viewable by the majority of people. Due to do, in a much more natural scenes and subjects photographed, and the depth of field will remain equal to human vision. Both with a large depth of field angle grows, as with a telephoto lens depth of field will decrease, whereas with this type of lens, we have no problem with depth fields.

First of all purchases, you must ensure that your case will accept the goal that you want to acquire.

Overall with standard lens you will have no visual distortion. Photographs taken with this type of Lenses seem much more natural because of the extremely minimum deformation. As with other types of Lenses should not forget that opening more or less can cause optical distortion even on such Lenses.

Due to the astonishing reality and optical perspectives very well preserved, the standard lenses are used in most photographic areas. Whether portrait, landscape, architecture, scenic or other. Such objective is the main type of equipment that everyone should have with his camera.

The majority of manufacturers Lenses and lenses have worked very hard to solve some problems of optical aberrations on most Lenses last thirty years. This is especially true for standard lenses. A picture made with such Lenses is easily viewable spoken by the majority of people, the fact a distance close to human perception. therefore it gives a vision natural scenes and subjects photographed and depth of field is equal to the vision.

Hello, I am currently reviewing the operation of the site and the photos present. I will do a housework within the present photographs and delete those that seem to me no longer to be valid technically and/or artistically. Thank you for your understanding. (07-22-2017)
