Sony a9 at a glance:
There is no free lunch and anything comes at a price. This appears to be true especially for Sony gear, always hyped and most of the time only because of the specifications sheets.
DPReview wanted to know better. They put the Sony a9 on their test bench, and found some interesting things. So, how does the powerhouse a9 perform when it comes to ISO-invariance (what is it?) and dynamic range.
DPReview found out that the Sony a9 is not ISO-invariant, and that “the camera is adding a fair amount of read noise that results in noisy shadows, limiting dynamic range at base ISO“. They also found that the Sony A9 sensor “was likely optimized for speed at the expense of low ISO dynamic range“.
What does all this mean? According to DPReview “this limits the exposure latitude of a9 Raws, so you’ll have some limited ability to expose high contrast scenes for the highlights, then tonemap (raise) shadows in post“.
All that glitters is not gold. Read DPReview’s in-depth analysis.

Sony pushing technological innovation. Sony press release:
Tokyo, Japan—Sony Corporation today announced the release of the new IMX382 high-speed vision sensor, which enables detection and tracking of objects at 1,000 frames per second. Sony will begin shipping samples in October 2017.
This vision sensor features a stacked configuration with a back-illuminated pixel array and signal processing circuit layer. The circuit layer is equipped with image processing circuits and a programmable column-parallel processor, delivering high-speed target detection and tracking. This configuration enables high-sensitivity imaging thanks to the back-illuminated pixel array, with target detection and tracking at 1,000 frames per second. The new sensor uses information such as color and brightness obtained from pixels to detect objects, then extracts the object’s centroid, moment and motion vector, and finally outputs the information from the vision sensor in each frame.
This vision sensor has achieved imaging, target detection and tracking at 1,000 fps on a single chip. This not only expands the scope of application, but delivers new value that was difficult to obtain with conventional systems.
While we still know very little about the Canon EOS 6D Mark II, beside some unsubstantiated claims about the annnouncement (Summer, they say), we have some specifications (pretty reliable, I guess) about the upcoming full-frame Nikon D820.
Concerning the EOS 6D Mark II. Please note that we got rumors suggesting Canon may not release an EOS 6D Mark II but a full-frame mirrorless camera instead.
