How To Choose the Best Digital SLR Lens

The DSLR lenses are one of the factors that have given these expensive cameras a definite edge over the other digital point and shoot cameras. However, the lenses must be bought carefully. After all, the quality of the pictures in a digital SLR camera largely depends on the quality of the lens.

Therefore, you must ensure that you are buying the right lens for the right camera. Here are some steps that are going to help you out.

Consider the Brand

When it comes to the DSLR lens, it is very important to consider the brand. After all, the lenses are brand-specific. So, if you have a Canon DSLR camera, you have to use lenses made by Canon. Well, you can use the Third Party lenses. They are quite affordable as well. However, the quality of these lenses will not be as good as the branded lenses. When it comes to high-end DSLR lens, Nikon and Canon seem to be the two companies that are way ahead of others. However, in recent times various other camera and lens manufacturers are making their impressions as well.

Some people tend to buy camera after considering their lens. If you already have a DSLR camera and lenses, it is wise to stick to the same manufacturer. That way, you can use the lens in your new camera as well. However, before doing that you have to ensure that all the lenses that you have, are compatible with the new camera.

Consider the Focal Length

Focal length is perhaps the most important factor that you need to consider before buying a DSLR lens. Technically speaking, focal length denotes the distance between the optical center of the lens and the sensor of the camera when the subject of a photo is in focus. The focal length of the lens is measured in millimeters (mm). Basically, the more the focal length, the more distance you can cover. For example, a 200mm lens can focus on a more distant object than that which can be focused by a 50 mm camera. On the other hand; the lesser the focal length of the lens is the wider the area that it will cover.

As a rule of thumb, the 55mm lens is considered to be neutral as it sees object as a normal human eye sees it. Any lens with the focal length of less than 55mm is called Wide Angle Lens, while lenses that has more than 55mm focal length is called Telephoto lens.

Consider the Zoom Range

Zoom of the lens is nothing but the difference between the lowest and highest focal length. For example, if a camera has the lowest focal length of 55mm and the highest focal length of 220mm, the lens will have 4X zoom. So, the zoom lenses offer versatility. There are super zoom DSLR lenses with the focal length varying from 18mm to 250mm. They can cover all the general photography needs. On the other hand, there are Prime lens that have only one fixed focal length. Though these lenses are not versatile, they offer the optimum quality pictures.

In general, the wide angle lenses are used to capture a scene where the idea is to capture as much as possible. For wildlife photography or sport, one needs the telephoto lenses.

Consider the Aperture

The aperture of the lens is another factor to consider before you buy any DSLR lens. Aperture is a small opening in front of the lens and it controls the amount of light to enter the camera. So, the larger the hole is, the more light it will allow. So, if you are interested in low light photography, you will need a lens whose aperture can be opened wide. Generally, the aperture is measured by the f-stop. Now, the fun with the aperture of a camera lens is the aperture value. The higher the number is, the less the hole will be. So, the opening of f/2.8 will be wider than that of f/5.6.

Consider the Size

It is important that you consider the purpose of buying the lens. If you are thinking about carrying it with you in your tours, you should be looking for a portable, light and compact camera lenns. There are lenses that will weigh more than a kg. Certainly, they are not the obvious options when it comes to portable lenses. Also, you should be looking for a DSLR lens that is easy handle. You don’t want something so big that it becomes difficult to carry it in your backpack.

Consider the Extra Features

Before buying any DSLR lens, it is important to check out the extra features that the lens is offering. True, the major factors for buying a lens should be the focal length, aperture and image quality; these extra features too, are worth considering. In fact, there are additional features such as the Vibration Reduction, or Image Stabilization that can really make a distinct effect on the image quality. At the same time, you should consider the lens mount, bags, and other features that are included in modern lenses.

Consider the Reviews

Reviews are very useful in finding out the right lens. Once you have zeroed in on a few DSLR lenses, it is useful to check out the reviews. That way, you will learn the pros and cons of these lenses. As these reviews are written by people who have actually used these lenses, you will get a fair idea about how the lenses actually perform. You will find many sample pictures taken through these lenses as well.

Check the Lens

The internet can be a great medium to get all the information, but when it comes to buying the DSLR lenses, it is important that you check the lens physically. You should use the lens to see whether it is working well. There are a few online sites that will let you use the lens as a trial before you buy it. That can be a great way to check out the real potential of the lens that you are looking forward to buy.
