If you process the footage with a red rocket card, it will look slightly sharper.
For me, when I first saw the Scarlet frames in RXC, it looked as if I had applied a 0.5 Gaussian blur in Photoshop to the image. Even the sensor noise was soft. A lens does not soften noise !
Indeed, taking a red rocket image and applying a 0.5 photoshop blur to it makes it look like the RCX image !
Many of us are very accustomed to RAW DSLR processing and are not worried if we see some gritty noise in the image. Gritty 'sharp' pixel noise is a natural thing, and can be removed remarkably well with denoiser tools like 'neat video'. Blurring the noise makes it harder for the filters to discriminate between true electronic noise and picture details.
I am still hoping that they will offer some more options on RCX debayer styles soon.
