If you watch from minute 5 on this video you can see how well the A9 autofocus tracking works. I can see sports photographer being excited to see such results. But we need Sony to release that 400mm FE lens soon ;)

Digglloyd shared a worrying finding on the Sony A9 he is testing:

I noticed some unexpected streaking in an image with a good exposure at ISO 100. The red channel is overlaid with horizontal lines/streaks in 12-pixel-high bands. Pattern noise is disturbing in any case, but to have it at ISO 100 with a good exposure is a huge negative for any camera, high speed shooter or not.
I’ve not seen noise this egregiously bad for years now. Possible diagnosis: the high-speed readout of the A9 sensor does not read out groups of rows evenly; there is some difference in gain between the rows. The pattern noise repeats in row groups that are 12 pixels high.

I have no way to verify his detailed test yet as you have to pay to read the full article. And I have to say I have found none such issue on the RAW files shared by DPreview and Imaging Resource.

I find it strange none of the reviewers so far has ever found any banding issue on the A9 at low ISO. My bet yet is that either he got a faulty production camera or he made some sort of setting error. I ask testers and readers to peer review this. Thanks!

If indeed his findings prove to be a general issue I am sure Sony will work to fix this very soon via the next firmware update. It’s very normal that new camera may have some issues that will be fixed quickly. Don’t panic yet ;)
By the way, that firmware update will likely bring S-LOG on the camera too. This is what Sony support wrote on the BHphoto Q&A page:

How well does the $9,000 Canon 500mm f/4.0 lens work on the new Sony A9? Well, check out this video from Paul Bunyard (first posted on our A9 facebook group). Note that he used the Sigma MC-11 adapter which officially doesn’t even support the Canon lens!
