Sony FE 2x Teleconverter
Because of their design, Sony FE 2x Teleconverter significantly inhibit a camera’s focus operation due to the loss of light reaching the autofocus sensor. When you mount the Sony FE 2x Teleconverter on a f/2.8 lens such as the Sony FE 70-200mm f/2.8 GM OSS, it slows it down to f/5.6, and when added to a f/5.6 max aperture lens such as the Sony 100-400mm GM, you are left with a f/11 max aperture. Most camera bodies won’t even autofocus with a f/11 max aperture lens, but the Sony Alpha 9 camera body maintains autofocus and subject tracking even with such a slow max aperture. For this review, I was able to test the focus performance on the Sony FE 100-400mm f/4.5-5.6 GM OSS lens. In the future, I hope to test it on the Sony FE 70-200mm f/2.8 GM OSS and recently announced Sony FE 400mm f/2.8 GM OSS.
Sony FE 2x Teleconverter performance on FE 100-400mm f/4.5-5.6 GM
Contrary to my preconceptions coming into this review, the speed and accuracy of the autofocus with the FE 100-400mm GM/ FE 2x combination is relatively high. The word “relative” is an important distinction here, with overall focus operation seeing a dramatic drop in quality as compared to the bare lens but remaining highly functional under the right conditions. This significant drop of the Sony FE 2x Teleconverter is most noticeable when trying to lock on to your subject under dim lighting conditions. In such scenarios, there just isn’t enough light reaching the sensor to achieve consistently good focus. However, when using this combination in midday light, the overall performance can be very good and honestly, it’s quite shocking given that the max aperture is a very dim f/11. The below shot of a Black Hawk catching a fish illustrates that with good light and technique, sharp photographs of relatively tricky subjects are possible with the FE 100-400mm GM/ FE 2x combo when used on the Sony Alpha 9 camera body. The hit rate in such scenarios isn’t nearly as high as with the bare lens, but the fact that you can even manage such a shot with a Sony FE 2x Teleconverter on an f/5.6 max aperture zoom lens is quite astounding. When photographing fast-moving subjects such as the birds found in the photographs above, Sony FE 2x Teleconverter is imperative to use the focus limiter found on the Sony lenses as it more than doubles the overall speed of the system.
Sony FE 2x Teleconverter sharpness
Inevitably, adding Sony FE 2x Teleconverter reduces both the sharpness and contrast of even the best lenses. The Sony FE 2x Teleconverter is no different as it is multiplying the aberrations and weaknesses of the lens it is mounted behind by a factor of 2 and there are now 8 additional lens elements for light to pass through. The image quality produced by a Sony FE 2x Teleconverter combination is highly dependent on the quality of the lens, with the top-of-the-line fast aperture prime lenses usually turning in the best performance
Extending the effective focal length of select Sony E-mount telephoto lenses, the Sony FE 2x Teleconverter increases the lens's magnification by 2x for a narrower field of view. The dedicated design of the Sony FE 2x Teleconverter maintains full communication between the lens and E-mount mirrorless cameras, including auto-exposure metering, autofocus, and Optical SteadyShot image stabilization. This Sony FE 2x Teleconverter is dust and moisture resistant to benefit working in harsh environmental conditions.
Sony FE 2x Teleconverter doubles your focal length
With the Sony FE 2x Teleconverter full optical quality and operability are retained, offering outstanding performance for sports of wildlife photography in a compact, lightweight kit. Multiplies focal length by Sony FE 2x Teleconverter with only a 2-stop light loss.
