After a while, you might start to think of adding another lens to be used with your DSLR camera. Choosing the correct lens for your DSLR / camera is trivial. It is only normal to add another lens. In order to make it easier for you, we differentiate the lenses based on the activities;
A. General Purpose Lens
Lens of this type is intended for general use, day-to-day photo taking, or as an upgrade to your kit lens. Note that some people stick with their kit lens as it is already enough or can be considered to be enough for the daily needs. However, better lens model is necessary to better quality pictures, wider range, faster focusing needs or brighter apertures (if you are a fans of low light photos or blurred background photos). These are the general reasons why people would like to upgrade their kit lens.
B. Close Up/ Macro Lens
As quickly mentioned above, you might prefer taking close-up photos of anything; models, flower, insects, or gadgets. Surely the kit lens will quickly disappointed you as they seems to refuse focusing on close range (if set in Auto Focus) and turning it into Manual Focus will directly ruin the photo too. Last, setting the camera into a Macro mode did not satisfy you or not close enough. Then you will need a macro lens or ‘Micro Lens’ as Nikon put it (it’s the same type of lens)
C. Wide Angle Lens
If you are an avid traveler, an outdoor enthusiast, or even an architect, most likely you will feel that the kit lens is not ‘wide’ enough to shoot the breathtaking views, the landscape, or the buildings. This is when you need to consider wide angle lens. This type of lens will enable you to take pictures with an angle wider than normal, thus capturing the large subject into one frame. Having a wide angle lens will also help you to take pictures in smaller spaces where you cannot step back any further.
D. Low Light Lens
Having a superior lens to be used in low light condition will quickly translate into lenses with large aperture to enable them to catch as many as light source possible to maintain a good quality photos. This will be essential if you want to take photos inside a room/ chamber with less light (such as cave or church) or where no flash is allowed. Note that where large aperture lenses can cost you more, your camera manufacturer should offers a wide selection of it with various f-values.
E. Telephoto Lens
If you enjoy taking photos from a considerable distance, either to capture moments in sporting events or take wildlife photography, telephoto lens should be in your wish list. In general, lens with focal length greater than 50mm is considered to be telephoto lens while lens with focal length greater than 300mm is known as super telephoto. Consider carefully about the focal length you need first when buying a telephoto lens.
Consider also: the focal length (do you take close-up photos or wide angle), the f-numbers (do you need a deeper depth of field to make a blurry background or not), and the VR (or Vibration Reduction) – very useful to compensate fast moving objects or camera shakes.
