For those times that you need extreme reach of a distant subject, Kenko offers the Teleplus Pro 300 3x DG teleconverter, designed to give optimal results with fixed focal length lenses of 100mm or more.
Corner resolution is stellar and deterioration of light is kept to the absolute minimum. Due to the 3 stop light loss inherent in a 3x converter, Kenko PRO 300 3.0X has no AF capability. The lens must be focused manually.
Teleplus converters have genuine Gate Array IC (Integrated Circuitry). It means that the converter's unique circuitry maintains signal integrity between the camera body and lens. These converters are designed to electronically operate the same way an original manufacturer's converter would provided there is enough light available.
Note: Kenko does not recommend these converters for lenses that have a zoom range that starts under 50mm.
