ARRI has a specific look and almost perfect directly out of the camera. Compare it to Red or Sony Venice and you see that it is the most appealing. You can make other cameras look like it, but ARRI is just industry standard and produces amazing colors. Their sensor is just fantastic.

Is it the sensor? I though it was the processing.

Yes. But No.

Red V-Raptor S35 XL has 16.5 stops of dynamic range with 250-12,800 ISO. ARRI Alexa 35 has 17 stops of range with 160-6400 ISO. Both use rolling shutters, both have native ISO of 800. Alexa has better low light noise reduction at higher ISO, but Alexa is sharper and has better dynamic range in low light since it uses 8K to 4K down sampling.

The real difference is in the colour straight out of the chip and how the workflow is for DIT on set.

THe major difference I think is that Arri is already easy to use and slots in to the Hollywood human knowledge base and workflows while RED was mostly used by indie filmmakers, documentarians, Youtubers, and Silicon valley people (if you work at Apple in the US you can buy RED cameras cheaply through company benefits). This pretty much created a different culture of what images should look like around the two cameras. an Alexa camera sets you back close to 80K and a fully equiped RED sets you back about 44K. So its easier to buy it and use it while hollywood rents it on the day for the shoots.

You can get a RED to look like it was shot on Alexa and vice versa in post processing today, but the people who work with the different cameras have different cultures of what is "cinematic" image.

You can’t compare the spec sheets. You need to look at the over and under tests. There is no camera close to the Alexa35 in dynamic range
