Camera Lens Filters

Having a good understanding of how camera lenses work, can have a very big benefit for you. One of these benefits is having the control and having no limit in what you can do. Thus choosing the proper lens just for your work can become a rather difficult task, since most probably you will have the issue of a financial nature. It often happens, that you need to sacrifice some characteristic for the other. The things that you will have to think about is obviously the cost. Other things that might come in handy to actually think about before purchasing a lens are the size, mass, the lens velocity and image quality.

This page is aiming to improve your knowledge about canon camera lenses, since they are the milestone in today’s digital photography. We will try to discuss the main topics to aid you in your quest to understand and feel what photography really is. We will talk about the image quality, the focal length, the specific zoom lenses, the f-number and of course the perspective.

Many people forget, or actually do not know that all cameras have lenses in them. Even the “one time use only” lenses contain several specific lens elements. For obvious reasons, each of these elements exists to redirect the path of light (photons) in such a way, that they recreate (render) the image, as closely as it possibly is, on to the digital sensor of the camera. The main task is to minimize unwanted elements, like aberrations, while still trying to use the least amount of elements, for the least possible price.

In case you did not know, the so called optical aberrations occur when certain points of the image, are not properly projected through the lens, causing the ray to land in a different spot – thus you have a many negative consequences. Some of them include but or not limited to: image blurriness reduced contrast, chromatic aberration (color misalignment).
