Getting Started With Camera Lenses For a Digital SLR Camera

!±8± Getting Started With Camera Lenses For a Digital SLR Camera

You may be totally confused about where to start, when it comes to buying a lens for your digital SLR. Is it simply a matter of bigger is better? What about all the confusing technical terminology? How are you supposed to make a sound selection and find a great value at the same time? If you have some basic knowledge to help get you started, it doesn't have to be a daunting process.

Concerning Focal Length

The first thing you will have to keep in mind is what is alternatively known as either focal-length multiplier or focal-length magnification. This is the conversion that results from the APS-size sensor used on a digital SLR. This means that your digital SLR lens is going to behave in a way larger than it really is.

A 50 mm lens really gives you an angle of view compatible to a traditional 75 mm lens, because the conversion is about 1.5 to 1.6. 200 mm would be 300 mm and so on. However, it's important to note that this only accounts for the angle of view, and doesn't actually change the optics principles or distortion of a particular lens sense or style.

Look Out for Apochromatic Correction

Aprochromatic correction, image stabilization and digital only lenses are a few other features or options to keep in mind. Starting with the latter, digital only lenses provide great value but won't be compatible with a traditional camera, or potentially future SLRs with 35 mm lenses. Examples of this include the Nikon DX.

Apochromatic correction helps to improve image sharpness, and image stabilization will help you get better shots by counteracting camera shake or blur from slow shutter speeds. Also note that some camera bodies, such as those from Sony and Olympus, are designed to provide stabilization effects, and other cameras rely on the lens to provide image stabilization.

The Best Brands to Look For

You'll certainly have a wide range to choose from, when it comes to brands. Canon, which has a great reputation for high quality lenses and camera bodies as well, is undoubtedly the most recognizable of the bunch. In addition, you will find some great choices from Tamron, Olympus, Sigma, Nikon and a range of other manufacturers too.

You'll find that some of these brands may offer more customized solutions for a particular setting or style of photography. You also may only be interested in using the same brand for the lens and the camera body. This often offers greater synergy and performance for your shots, but it isn't a necessity in most cases. Whether or not you'd like to do this is entirely up to you.

This has been just a basic starting guide for camera lenses and digital SLR cameras. There is definitely more to consider, and of course you will have to cross the bridge of how much cash you need to end up spending as well. It's always better to buy one versatile, high quality lens than needing to buy a variety of more limited and lesser quality lenses, but you will always be able to find a great match for your specific needs and your budgetary constraints, whatever they may be.

In order to enhance the quality of the photographs that you take with Dslr cameras, it's useful to understand the differences between the types of lenses that you can use to produce varied effects. After all, the quality to convert lenses is one of the core features which differentiates digital Slr cameras from contract digital cameras.

Normal Zoom Lenses
Don't be misled by the term "normal" because these lenses can of course cover quite wide angles of view when they are zoomed out to the maximum wide angle range of their capacity. Their use can also be extended to cover medium telephoto aspects and they are great for shooting casual shots of well-known things such as landscapes and groups.Being relatively lightweight and contract they are fairly compact, manufacture them great to carry nearby to capture everyday events and take great vacation photos.

Telephoto Zoom Lenses
A good example of uses for telephoto lenses is if you are at sporting events such as football games and want to capture the operation of the pitch when you can't get close. Telephoto lenses have a narrower angle of view than normal zoom lenses, which is also good for cutting out the background from a picture.They are mainly carefully to be good for portrait photography because they furnish the quality to separate a field from its background by defocussing the background.

Wide-angle Zoom Lenses
These are great for landscape shots or in tight spaces which don't allow alot of space to move back from the object of focus, wide-angle lenses enable you to capture objects that wouldn't fit into a photo or photo with a normal zoom lens. With wide-angle zoom lenses it is important that you keep the background uncomplicated in order to produce some great photographs.

Macro Lenses
Macro lenses enable you to get up close and personal with the object of your focus because they are designed to focus at much closer distances than other lenses. They are great for capturing fine details and are often used in nature photography to capture small insects or details of flowers.

Fisheye Lenses
Good for providing a unique dome-like consequent at the edge of photographs, fisheye lenses produce very wide angles of view with unique renderings that heavily distort straight lines.

Tilt-shift Lenses
If you want to contend your perspective in a photograph, tilt-shift lenses are very specialised lenses that enable the perspective between the lens and the sensor to be adjusted straight through tilting and shifting. The tilt movement is able to focus on both near and far points with depth or join the focus or just a single point in a picture. The shift movement works by correcting the oblique distortion which is normally seen in photographs in which you are looking up at an object such as a building. Parallel lines are kept parallel instead of the usual oblique consequent in which the object of focus would appear to be more narrow towards the top of the shot.

So there you have a breakdown of the different types of lenses you can use in order to get to grips with developing your skills at digital photography using digital Slr cameras.
