Tamron Teleconverter Camera lenses for Nikon

Features of Tamron Teleconverter Lenses for Nikon Cameras

Teleconverters are secondary lenses that you can use for taking pictures when you need to get closer to the subject. Wildlife photography is an example of a situation in which you can't always move as close to the subject as you would like. Tamron manufactures several types of these lenses for Nikon cameras.

This secondary lens increases the focal length. It is usually attached between the primary lens and the camera body. The magnification effect of this lens varies depending on the magnification of the specific product. You can find them from 1.2x to 3.0x. Tamron typically makes their Nikon lenses in 1.4x and 2.0x magnification. Photographers use this type of camera lens when they need a closer shot to see more details of the subject. Because most birds are small, the secondary lens helps them appear larger in the picture. Some sports photographers also use this type of lens to focus more on a particular player and less on his or her surroundings.

When seeking the teleconverter that's right for you, here are factors to consider:

• Compatibility: Find out if the secondary lens you're considering is compatible with your camera model.
• Focus type: Decide whether autofocus is a necessity for you. If it is, you will need to find a teleconverter that lets your camera maintain its autofocus capability.
• Magnification: You should also understand the effect the teleconverter will have on your primary lens. A 2x magnification increases a 70-200 mm lens to the equivalent of a 140-400 mm lens.
• Aperture: You should also consider the aperture. Shutter speed will slow with a teleconverter; this could affect your camera's performance in some lighting conditions.

When you want to use the teleconverter, attach it to the camera body, then attach the primary lens to the secondary lens. You should also account for the natural loss of available light that occurs. The light decreases by 1-2 f-stops, depending on the magnification and the primary lens. Practice with the secondary lens until you get the hang of it. Some professional wildlife and sports photographers take pictures with a teleconverter when they find it appropriate for the shot.

You can clean the lens by applying lens cleaner to a 100% sterile cotton pad and wiping the optical surfaces. Make sure that the cotton is absorbent. You shouldn't use cotton gauze. After you have wiped the optical surfaces clean, you can blow canned air on then lens. Alternatively, you can use a lens cleaning pen for the finishing touches.
