There are a bewildering number of choices when it comes to lenses for SLR cameras. From wide angle to telephoto, zoom lens to Prime, fish-eye lens aperture, wide aperture, the choice seems to be impossible. It is not real. What it's about, ask yourself, is a simple question: What do I want to shoot?

Different lenses for different subjects

If you are just starting in photography, chances are you are still experimentingand find out what do you shoot, too. You could shoot a few family pictures and landscapes of one days from your next vacation. On the other hand you can from the start that you have decided to love the photos of wild animals and that is everything you want to. Either way, the lenses needed to get the most out of these issues are very different. To view an image fits into the vastness of the landscape viewfinder, you need a wide angle lens. However, attempts a portrait with the acquisitionsame lens would result in a tiny person and not much else in the frame, unless you are right that the person's face and smelled their breath. In an attempt to take a picture of a wild bear in 100 or more meters is easy (not possible and you really do not want more) get a wild bear. In a perfect world you would have 3 different lenses for each of these topics. But in a perfect world you'd be a millionaire and be able to afford them all. This is what to doto decide what kind of photography interests you and select your lenses accordingly.

Length: Zoom vs. Prime

There are some advantages with both zoom and prime lenses (fixed or non-zoom) lenses. On the one hand, zoom lenses are versatile, and reduce the need for a whole bag full of lenses that you need to change and change again while you are on the hunt. On the other hand, a good quality prime lens can be gold. Prime lenses, if theywell-built, generally produce a sharper, better picture quality. This is because they have fewer moving parts and broken glass. Therefore, the light that must not happen, how many objects and is therefore less common. The other big advantage of prime lenses is that for this reason, they tend to be "faster" than zoom lenses. Practically, this means that you can use slower shutter speeds, like the lens needs less light for correct exposure created. This is particularlyuseful if you want to take portraits with available light.

Aperture

Another important factor when selecting a lens is its maximum aperture. This is shown in the description of an f-symbol. Eg. f/2.8. The lower this value, the wider the opening decisions. For example, if you were to take a portrait features only person in your focus, you have a large aperture. If you want to take to a sweeping landscape, where everything must be central towould be a narrow (high usage) aperture. Select a lens with a larger opening gives you more options when hunting.

It is known that lenses can cost as much or more than the cameras themselves. It is also worth mentioning that with lenses you get what you pay for. Although no single device can make the difference between a good and a bad image a, a well-integrated with high-quality glass lens can cause sharper images. Therefore, it is worth considering theLenses you buy carefully and invest in the best quality you can afford. Knowing what type of photography to pursue, you can make this process a lot less daunting and less expensive.
