Imaging Resource published their CP+ interview with Sony. Here is the recap courtesy of SonyAddict:
Sony thinks they can continue to increase high ISO performance
Pixel surface area matters more than the depth
Sony thinks IR gets a little too deep for readers when they continue to push for how Sony will improve performance
Sony just wants it understood that only they have the sensor technology that allows for good high ISO performance right now and will continue to push the mirrorless market forward
To get AF tracking right you have to go beyond pixel data and go to object orientated tracking
Having the imaging and AF data together lets this smart AF system work in a way DSLR’s can not
At some point in the future, the camera might have some AI involved inside for tracking
Currently, Sony is using general computing for AF, but by the time next gen CPUs come out for cameras, Sony thinks they could have AI in the camera for AF.
Frame rates are getting fast, but currently, there isn’t a great method for taking a frame out of the video for photography.
Video and photos also require a different mindset
Sony tests 100 different types of AF scenarios when developing their AF system
For developing their long telephoto AF they have gone beyond testing 100 different types of AF
Sports and nature require a lot of additional testing and Sony is putting addition thought into their interface
The 400mm f/2.8 was developed to satisfy sports and nature photographers
The 400mm f/2.8 will be light and it balances well on their current bodies
