ARRIALEXA 35

A 4.6K Super 35 sensor with the fastest scan in this lab. Every smaller mode is a window read pixel for pixel. ARRIRAW frame rates depend on the drive, so the table gives both.

Sensor 27.99 × 19.22 mm (Super 35), 4608 × 3164 photosites, 6.07 µm pitch, rolling shutter.

Drawn to the same scale on every camera page. Grey is the whole sensor, the coloured figures are the open mode.

Choosing a mode

Every mode scans in under 8 ms, so pick for the lens and the frame, not for skew.
Anamorphic: 3.3K 6:5 with 2× lenses, or 4.6K 3:2 open gate with 1.5× and 1.3× lenses.
High frame rates in ARRIRAW want the 2 TB drive. On a 1 TB drive open gate stops at 35 fps.

≈ marks an estimate. * marks an uncertain readout: nobody has measured that mode on this camera, so the figure is worked out from a measured mode by line count, from a camera on the same sensor, or from the frame rate it reaches. Top frame rate is the highest the camera offers in that mode, in its best codec and on its fastest media; other codecs often stop lower. Readout is how long the sensor takes to scan one frame from top to bottom, which is what leans verticals on a fast pan. Under 10 ms is comfortable handheld; past about 16 ms fast movement starts to lean.

Frame rates from ARRI's ALEXA 35 specifications, standard licence, without Sensor Overdrive. Readout figures are CineD lab measurements. Modes and frame rates change with firmware, so check the current manual before a job depends on one. Dynamic range for this camera is on Dynamic range by camera.
