Bought this for with my 70 to 200mm G Master - works a tear.

I wanted to extend the reach of my Sony A7iii and 70-200f2.8GM for occasional wildlife shots and couldn't justify the 100-400GM so turned to the 2x convertor. I have not been disappointed as the combination retains superb image quality and the fast autofocus/tracking that these camera achieve. The convertor is very well constructed and comes in its own soft case for protection. Its fit and go and is transparent in use, apart from dropping widest aperture to 5.6, but I figured I can compensate by ramping up the ISO. The purchase has been everything I was hoping for, allowing me much closer shots of wildlife (and anything else for that matter!), is fast and accurate to focus and IQ is excellent. For example, it locked onto a small swarm of flying insects, followed them and I was able to take a sharp shot of them. It also tracked a duck taking off and remained locked on the focus even though it flew beyond a tree. It has really expanded my interest and ability in wildlife and action shots without costing the earth. Would I recommend it? Yes, at the drop of a hat!.

I mainly use this with my 100-400 lens - an excellent combination for distance, wildlife & detail photography.

Purchased to use with the 70-200 and results are excellent, there is a slight loss in quality but better than expected when adding more glass to a lens, I am looking forward to testing with the new 100-400 when released. However it is an expensive 2x converter, would I purchase again, absolutely..
