It's immediately obvious the a9 is not ISO-invariant. This means the camera is adding a fair amount of read noise that results in noisy shadows, limiting dynamic range at base ISO. That's why, for the same focal plane exposure, performing analog amplification by increasing ISO in-camera gets you a cleaner image than performing that amplification (or brightening) in post-processing.
It's not the typical performance we've come to expect from Sony sensors and we suspect the higher readout speed is leading to greater noise. In other words, it appears this sensor was likely optimized for speed at the expense of low ISO dynamic range.
Just a trade-off that many people will not care about, IMO.
Well, if you want to share with us, you can post a link to your website, or to a share-folder, Dropbox-like...bakubo wrote:I was at Bic Camera today in Japan (been awhile since I stopped in to a camera store) and they had an A9 sitting out with 24-70mm f2.8 attached and no one looking at it. I played with it awhile and took a couple of photos. No one posts on this forum anymore though so I won't go to the trouble of writing anything more or posting any photos.

The Bridge with the Leica 25-600 does all I want. As I'm only a happy snapper, not a pro or even a camera club competitor
