Unfortunately, the download doesn't work for me.  It takes me to a blank web page:

metabones.com/download/of/MetabonesAppV1.8.exe

Anyone have success downloading?

[John Hollenberg]

OK, downloaded successfully.  I must have tried before they got the links all in order.

Update was very smooth, took about 2 minutes.  With firmware 0.43 installed auto focus works very well with a7r2 and Canon 24-70 f4 L IS.  Happy camper here.!

Wish Metabones would make one for Sony and Nikon lens.

70-200/4 is usm lens works perfect.
24-70/4 is perfect as well.
100-400 is usm ( version 1) works over the whole range at all distances without pumping, but slow.

Any idea how well the Mk III adapter works with the A7rII's AF? I got several of them for free as part of a Sony promotion when the A7r was first released.

someone wrote you can send them to metabones to get them updated to the newest fw version, than they work as the version 4.

[John Hollenberg]

For those who missed it (like me) Tony Jay pointed out that a few days after 0.43 was released, Metabones released firmware 0.44.  According to their site, the change is:

"Fixed IBIS switch issue on A7II and A7RII with IS lenses introduced in V.43."

Thought others would want to know.
