The MC4 AF 2.0X DGX converter has genuine Gated Array IC (Integrated Circuitry). This means that not only the converter’s own unique data but all data sent from the camera body provides full exposure metering and linkage for electronic flash photography.
Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm. However, full AF operation is only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera’s AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.
