Even though having a decent SLR camera is enough for taking good pictures, the lens you use makes a huge difference. The lens that comes with the camera is usually not very good and has many disadvantages. When buying the best SLR lens, it’s important to consider a few things:

1. Aperture: The aperture of a lens controls how much light passes through to the film. A small ƒ-stop number, such as ƒ/2.8, allows more light to pass through than a larger number, such as ƒ/5.6.

2. Focal length: The focal length affects what you can photograph with it. For an outdoor scene, you will need a wide-angle lens. If you are photographing something far away, then use a telephoto lens that has the most reach for its size.

3. Image Stabilization: This feature helps you photograph things far away without blurring the picture because of your movement.

4. Macro lenses: Most SLR cameras come with a macro lens that can take photos at close range. It’s important to know that these lenses aren’t perfect for photographing anything further than arm’s length.

5. Filter Threads: The filter threads on the best SLR lens are used so you can attach a filter to the lens, such as a polarizing filter.

6. Image Quality: The quality of the images taken with a camera is usually dependent on the lens instead of the camera body itself.

7. Weight: If you are carrying your SLR and its lenses for long periods, lightweight lenses will definitely be better.

8. Price: The best SLR lens doesn’t necessarily mean the most expensive one, even though you could get more for your money with an expensive lens.

9. Zoom: Although you will certainly want a zoom lens, it is possible to take better pictures with a prime (i.e., non-zoom) lens such as the Nikon 50mm ƒ/1.8D AF Nikkor Lens that can be purchased for under $200.

10. Weather Resistance: Although most lenses today are made to be weather resistant, you need to make sure that the one you buy is and can handle whatever conditions it might face out in the field.

In conclusion, you need to consider the best SLR lens for your needs and know that it can be worth spending more on a high-quality product instead of one with many features you don’t care about.
