Dpreview just posted the full Sony A9 review. The camera earned a Gold Award:

While we’ve seen that there are still trade-offs versus high-end DSLRs, the Sony a9 is a fantastic and highly capable camera, and the fact that it’s comparable to those DSLRs speaks volumes. The Nikon D5 and Canon EOS-1D X II are both the result of decades of research and experience, and the fact that Sony has arrived with the a9 less than four years after creating its first full-frame mirrorless camera is nothing to be sneezed at.
If you’re drawn to the ideas of silent operation and a compact package (with the right lenses) and yet you have a need for the type of speed the a9 offers, you won’t be disappointed.

Good job Sony! Now bring on the new A7III, A7rIII and A7sIII :)

SAR reader Benjamin sent me this:

It seems the “star eater” bug is not fixed. Preliminary findings indicate, that the Sony algorithm now processes both green channels at once instead of seperately. This slightly reduces the overall filtering effect, but also seems to cause a green color cast on the smallest stars.
The details are discussed in these two threads:

Also John Leathwick confirmed on an article written for PetaPixel:

When Sony made their firmware announcement last week with promises of improved image quality for long exposures, many of us thought that this problem might at last have been addressed. However, slowly the evidence began to build that this was not the case – in my own testing of night-sky photos taken with the new firmware, the number of stars detected by the freely available image stacking software DeepSkyStacker is 70% lower in 5 second exposures than in 2.5 second exposures; visual comparison of these images shows the removal or dimming of many of the smaller stars once exposures are four seconds or longer.

Disappointing. Now let’s hope Sony will take quick action on this matter!
