The camera lens - Zoom vs Prime

The first thing you should decide to purchase or use of glasses to be taken is whether you want a zoom or a prime target. In other words, a lens with only a fixed focal length. Zoom, many remember the obvious choice because you get the same lens covers all focal lengths in one-and-the-. It 's very flexible and does not need to carry extra lenses and the sharing of wasting time> Lens on the other. Want to make great landscape? Zoom and click OK. You want to detect the expression of his face to anyone? Larger, click. These are certainly great advantages over the fixed focal length, where you are stuck with the same focal length. But prime lenses have their advantages. In general, smaller, faster, cheaper, sharper, less distortion and less prone to damage zoom. Consider all of a sudden the valueis not it? Let's take a detailed look at the numbers first.

A fast lens, you say?

prime lenses can not be used as many lens elements (layers of glass) that make them zoom. And this is the key, it's simple structures and thus smaller and cheaper. Now, what this fast to be the first? It 's still a piece of glass, is not it? Not a race car! Well, when photographers talk about a fast lens is a bit 'Nonsense. What you should say is that the lens has a fast opening of the light can pass over the lens, so that the shutter of the camera right on the nail. It 's easier to simply say that "the goal is fast." With one of these objectives faster which gives some options. You can take light frost and fast action situations with high (large aperture and shutter speed) and you can easily take pictures in handlow light (the grand opening and a lower speed). Please note that if you have a large opening in the area (the "Focus") is smaller. Things in front of it outside the home will be played behind the point of focus. This is not necessarily a bad thing, but it can help draw attention to the main subject of the picture and to win away in the background. Greater openness and greater focal length to use, more developmentbe.

But back to prime lenses with simple structures, other benefits were mentioned in their superior image clarity and lower distortion. In particular, the emphasis can be useful if you plan to send photos to an agency of photos. 10 to 20 mega pixel photos is a great achievement of your goal.

And finally, because the fixed focal length of zoom can not, there's one less thing to break!

The choice between zoom and primeis not always so easy. Also, some people think that the only prize focal limits, while others have found liberating to think they can find something less. Personally I use both zoom and prime. When I'm in a situation of rapid change things around me, I prefer the flexibility of the zoom. But when I go on a roll with a particular expression in his eyes, I prefer to use the appropriate lens wide and long commodities.
