Thanks to the unified design when mounted to a compatible lens*, the teleconverter is weather and dust-resistant and operates at temperatures as low as -10°C. This makes it possible to be used with confidence outdoors when used with a weather and dust-resistant camera body and lens.
High image quality design which maintains the optical performance of the original lens: Construction of 7 elements in 3 groups maintains the optical performance of the original lens. By using the optimal image quality parameters for the overall characteristics of the original lens and 1.4x teleconverter, an excellent imaging performance with great aberration suppression can be achieved even when the focal length is multiplied by 1.4x. The camera displays and records information reflecting the change in aperture and focal length when the teleconverter is mounted.
The camera’s autofocus performance is unaffected by the addition of the teleconverter: An AF speed equivalent to that of the lens by itself is still achieved when the teleconverter is mounted. Thanks to mirrorless cameras’ “Live View” Contrast Detection autofocus, shooting at minimum aperture values is still possible despite the f-stop being increased by mounting the teleconverter. Also, accurate focusing at super-telephoto focal lengths with shallow depth of field is possible thanks to the AF performed by the image sensor.
Weather and dust-resistant and -10°C low-temperature operation: Using the teleconverter together with a weather-resistant camera and lens does not affect the weather resistance of the system.
