This is an initial review of the Sony FE 1.4x Extender for Sony 70-200 F2.8 G-master. Full disclosure, all products were paid by me and no equipment was given to me for this review.
It’s easier for me to breakdown my review into components, but again, this is an initial review, so my comments on the subject may change.
The actual adapter is built really. It’s made of the similar if not the same material you will find on the Sony 70-200 G-Master. You will also find weather sealing gasket on the back side of the lens, similar to what you will find on the 70-200 G-Master.
If you use the 1.4x extender, you’re full frame Sony Mirrorless camera will give the 70-200 a range from 98-280mm. On the other hand, if you use an aps-c camera like the a6300, you’ll see a range of 147-420mm which is fairly significant. You will also see your aperture lose a stop of light from F2.8 to F4.
My initial results of its performance is very good. As shown in the video, I tested out the lens at a track meet. I shot entirely at F4. I used AF-C as well lock on AF. The results I got were imperceptible to that of the lens without the extender. However, as you’ll see in the section below, there might be some fine tuning I need to do with regards to the lens performance. I’ll need to do further testing.
The quality of the image is good. However, you will notice a hint of softness in the image at full resolution. Unlike using the native lens, which is very sharp when it nails focus. I think there is an issue with auto-focus. It appears the focus is just not hitting the face of the subject. I will have to do further testing to eliminate this problem. I may decide to use face-tracking to see if that will help.
