Just got back from Africa and found the A7II, Tamron 150-600mm combo were just about perfect for safari shooting.  Had my trusty Sony RX100II for anything that got close.  Given most subjects are hidden in grass or trees manual focus with focus peaking was the best route and worked well.

Here is the Africa Gallery http://aquabluedreams.com/#/gallery/africa-2016-hwange-zimbabwe/dsc4942/

 

Again most of the pictures were taken with:

 

Sony A7II, Sony LA 4 adapter, Tamron 150-600mm Lens.  A few were taken with the Sony 24-240mm and the Sony RX100II.

Your Africa Gallery is amazing. Most of your shots are absolutely breathtaking!! Well done!! Thank you for sharing.

Thank you.  On a previous trip due to rain we did not see one big cat.  This trip it rained the first 4 days and looked like it was going to be a repeat but due to the hard work of a wonderful guide we found cats the last two days!  Again the 150mm - 600mm on the A7II was perfect.

Great images. What adaptor were you using for the Tamron? How was the autofocus performance, would it work for birds in flight?

Nice photos. Sharp color!! 

 

re GLK: not a great job to capture BIF. the lock-on focus not really working.

Using the Sony LA 4, adaptor.  I don't know if it would focus on birds popping up out of the brush but it was fine for something you could keep in the middle of the frame and just flying along.
