Nikon was founded in 1917 and began producing lenses and cameras in the 1930s. Since then, it has produced many outstanding lenses and cameras for the beginner, amateur and professional photographer. Sigma is a manufacturer that produces, among other things, generic lenses that can be fitted with mounts to fit Nikon and other manufacturers' cameras. When considering whether to buy a Sigma or Nikon lens, there are a few things you can do right in the camera shop to see how the two compare.
Instructions
1. Attach the Sigma lens to your Nikon D60 camera by lining up the red guide dots and rotating the lens until locks into place. Hold the lens and camera as you normally would and see how the lens feels in your hand. The materials, design and set up (the way the focusing ring turns) of Sigma lenses may feel different than the Nikon lenses, and for some people this is enough reason to buy the Nikon lens. Remove the lens and replace it with a Nikon lens to how the two compare in feel. Put the Sigma lens back on the camera.
2. Hold the camera to your eye, and, using the lens in auto focus mode, focus on a subject that is close to you, then one far away. Pay attention to how long it takes the lens to focus and how loud the internal motors are when they are working. If you will be using the lens in situations where you don't want to draw attention to yourself, the noise may be a consideration. Perform the same test with the Nikon lens.
3. Reattach the Sigma lens, hold the lens towards the ceiling or other white object and take a picture. Review the picture on the rear screen and zoom into the corners of the image. You are looking to see if the lens is sharp corner to corner. You also are looking to see if the corners go a little dark, this is called "vignetting" and it can be visible in any manufacturer's lenses. Connect the Nikon lens and perform the same test.
4. Reattach the Sigma lens and take a picture with camera either on a tripod or resting on the counter. Review the picture and zoom in as much as possible to see how sharp the image is. Connect the Nikon lens and perform the same test. Finally, compare the cost and value of the lens.
