Sony FE 2.0x Teleconverter

Buying a teleconverter over a longer lens for financial reasons can make sense, especially as the very long focal length lenses are considerably more expensive than teleconverters. Using teleconverters to save space (vs.

I've been using my FE 2.0x teleconverter on both my a9 and a7RIII, in combination with my FE 100-400mm f/4.5-5.6 GM OSS lens. The performance is excellent in sunny light, shooting at f/11.It's very important to use the correct AF mode for the circumstances.

Focusing fast and accurate on SONY 200-600mm also produce sharp image.

On some A7R3 cameras this will give you a false sense of auto focus capability until you go home and process your blurry pics. Always manually focus after 650mm on this beast. If you have the A9 camera, it will perform a little better than the r2 and r3 series.

Amazingly good, especially compared to 2x Canon converters I have used. I tested this on a Sony A7rMk2 with the 100-400mm Sony GM lens and a focus test chart. I compared images taken with a Canon 800mm (with Metabones adapter) on the A7r2 against images with the Sony 100-400 at 400mm and the 2x on a...

I used the 2x with my Sony a9 100mm - 400mm zoom. This made it 800mm at max. I went to the San Francisco Zoo and shot about 27 animals at max. Most were great, clear, sharp shots but I did get about 5 shots that showed problems with focus & vibration control.

Recently I took approximately 100 pictures of birds and small animals. I used Sony FE 2.0 Teleconverter with my SEL100400GM and Sony A7RII. It was a perfect match. I did not notice any significant auto/manual focus or sharpness issues.

I got this to add to my Sony 400mm f2.8. It's a perfect fit. The lens still focuses quickly and before you know it you have an 800mm f5.6. You can program a button to go to crop sensor and then you have an image that looks even closer.

I like this teleconverter for the extra length, but you should expect the focusing to be a tad bit slower than when using the 70-200 without the converter. I had some issues with the lens hunting more than usual, especially when trying to do shots of a track meet and also had some trouble with dogs.

Loosing 2 stops is tough, but man, 400mm hand held and sharp as a tack is great. I have it on a Sony 70-200GM and it really puts you out there. Crushes depth of field and with the a7riii set at crop (2x) you get a whopping 800mm effective focal length.

It does what it should, it is great , you just add a 140-400 to your bag with this little thing, Great quality build and really keeps the GM quality glass. The only problem is that the AF is not very fast to track objects.
