ARRI Alexa 35 Sensor Modes

The new ARRI Alexa 35 camera (aka the ARRI S35 4K prior to its launch) has nine sensor modes, giving a total of fifteen recording formats (or twenty if you include both ARRIRAW and ProRes where available for each format).

It can be difficult to remember the image circle, clip resolution, codecs and maximum frame rates offered in each mode, so we've summarised them for you here.

Here is an interactive visualisation of the different sensor modes of the Alexa 35. For each mode you can see the number of pixels (photosites) of the sensor used, the physical size of the sensor area used to record the image, and the image circle needed to cover the sensor mode (useful for determining if your lens choice will cover the mode you intend to use).

Hover over an area or click/tap it to see a summary of the sensor mode.

Some sensor modes allow you to choose a clip resolution different to the number of pixels used by the sensor mode, while others do not. Modes also offer different codec options (ARRIRAW or ProRes) and maximum frame rates. Below is a breakdown of the options available for each mode.
