These teleconverters can be used to effectively extend the focal length of telephoto lenses. In general they can be used with the following lenses.
- 105mm 2.8 AF-S Micro
- 70-200mm 2.8 AF-S
- 200-400mm 4.0 AF-S
- 200mm 2.0 AF-S
- 300mm 2.8 AF-S
- 300mm 4.0 AF-S
- 400mm 2.8 AF-S
- 500mm 4.0 AF-S
- 600mm 4.0 AF-S
In general all the above lenses will work very well with the 1.4 teleconverter, however the f/4.0 lenses may have some difficulty auto focussing with the 1.7 and 2.0 teleconverters. In bright lighting all teleconverters can work quite effectively. It should be kept in mind that all teleconverters will degrade the image to some extent, however this can be hardly noticable and the degradation will increase with the 1.7 and 2.0 teleconverters.
The best lens quality is acheived with a lens without any teleconverter, however for photography of subjects such as birds, teleconverters can be invaluable.
This AF-S teleconverter provides a 1.7 times increase in the main lens. The teleconverter extends the focal length of the primary lens by 1.7 times, with a one and a half f stop loss in effective aperture.
All normal lens functions will operate with this teleconverter in use.
