Deciding on the best camera lens means that you need to have a great deal of knowledge of the various lenses available and how they work. Hopefully you will learn here how to best select the proper lens for your particular photo shooting requirements.
If you do plenty of shots of landscapes and outdoor scenery, you should look into a wide-angle lens. One of those SLR lenses has got a field of vision that’s significantly wider when compared to the human eye. This simply means that it will give you a significantly wider perspective of the world in your shot. A great wide angle lens has the means to keep both your foreground and background in sharp focus. This is certainly something else that your eyes can’t do. The wide angle lens is the best option for you if you are shooting a big, dynamic outdoor scene in which you need both the foreground and background in focus.
However, most likely you don’t want to utilize this SLR lens if you want to concentrate on the certain details of one subject in the frame.
In this case, a zoom lens might be the better option for your needs. You can utilize a zoom to lengthen or shorten the focal length to make the magnification more or less. This makes a zoom lens one of the most popular and versatile accessories for many photographers. But you have to remember that a zoom lens has a small aperture. It is not the best suited lens for low light conditions without a flash.
You will notice that zoom lenses have supplanted fixed focal length (prime) lenses in most SLR camera kits that you buy. Please keep in mind that optical zoom is very different from digital zoom, though.
Your optical zoom actually magnifies the subject. And the digital zoom will crop the image once you have already maxed out the optical zoom. Generally the digital zoom will enlarge/crop the image in your viewfinder. The digital work gives you a closer image, but the quality is poor and the resolution is not good.
A telephoto lens is a little different. A zoom lens will enlarge and magnify the subject of the image. However the telephoto lens will make the subject become closer to the shooter. This will minimize the distance between the objects in the frame and the lens. This will allow the lens to reveal more details than your eye could resolve at the similar distance.
