A7RII with Sony A Mount 70-400 II Zoom

Anyone have direct experience with the Sony A Mount 70-400 II zoom on the A7RII? I have read reports that it does not work at all in Lock On AF-C mode with the LA-EA3 Adaptor, but that it does work in that mode using the LA-EA4 adaptor and Contrast Detect AF (no Phase Detect AF), though not great.
Thanks.

Guy's I have the 70-400 G1 but neither the 3 or 4 A-E adapters as of yet so I won't be able to help in this area for quite awhile.

I own the A7r2 and the 70-400G2 and LAEA3 adapter and have been using them with excellent results.

The AF is quick and accurate but no tracking is possible.

The AF-C only works in either single shot or low speed continuous modes, not in the 5fps high speed mode.

I have not tried the contrast detection option at all.

As I said, results are excellent but, at 2 fps, and without tracking, it is not a sports camera. Although, I was quite happily shooting surfers.

It is, naturally, a different experience than the 15fps I get from my NX1.

My experience is with the Sony 70 400 MI on the A7RII with the La-EA3 adapter. Focus is not brisk, but adequate in daylight. Even hand held images are pretty amazing even at 400mm f5.6 iso 6400. Here's an example of a tripod mounted straight out of the camera jpeg just to give a sense:

Still have not learned how to post an image even listing a URL from Flickr
You have to grab the actual image URL which ends in .jpg.

On flickr, click the little download arrow in the bottom-right of your picture page and select "View all sizes". From there you can right-click and select "Copy image URL" or "Open image in new tab" to get to a direct .jpg link (these are the right-click menu options in Chrome).

Thanks. Think I got it.

Does it open automatically?

No because your URL is incomplete : the beginning is missing (http://www.. etc)

Please don't include full size pictures in the thread, post a smaller version with a link to the full size image if you want us to get the full sized picture)
