The SRW9000 will have a memory card recording option in some months. This is a flash memory card that will be 1 Tb and record uncompressed. This memory card option will also work with the F23 and the F35. There is also a 4k upgrade path for the camera section. Which makes sense as this special 1 Tb cartridge will be capable of 5 Gbps.
Sony and Arri are adopting similar approaches, that of recording to a know medium and format. Easy to store, edit and manipulate. Both are good cameras and I wish there was a Alexa vs SRW 9000 comparison instead of film.
For us in India, unless post houses use the Direct to Edit Apple ProRes function of the Alexa, both will become HDCam SR cameras. So rentals will be similar. It will boil down to which camera cinematographers prefer.
Eventually the 1 Tb SR2.0 card will be introduced. And some may demand the raw recording capability of the Arri Alexa or uncompressed for the SRW 9000 over ProRes or HDCam SR. But both these approaches take up huge amounts of disk space so they might be non-starters in our context.
There was a very basic test of some shots with the SRW 9000 shot a couple of days ago. These were shot as S-log. The camera played the tests directly with and with a 'linearizing' LUT applied. I felt the test was playing at double speed. Meaning, they were shot 1080p25 or 1080p24 and the camera system was set up for 1080p50 or 1080p60.
