Not content to let RED have all the drone and gimbal fun, ARRI has just introduced the ALEXA Mini which takes the image quality of the original ALEXA and shoves it all into a much smaller Carbon Fiber package. The camera is capable of up to 200fps 2K ProRes and 30fps 2.8K ArriRAW recording to internal CFast 2.0 cards (60fps at 4:3 and 120fps at 16:9 if you go to a Codex recorder).


Here's a quick rundown of the Mini:

The ALEXA Mini can be operated in a number of ways: by wireless remote control, as a normal camera with the ARRI MVF-1 multi viewfinder attached, or with an on-board monitor and controlled via the user button interface on the camera body. Light enough to be comfortably held at arm's length in a hand rig, its compact size and extremely quiet operation also make it ideal for tight shooting conditions. The symmetrical design permits filming in any orientation, including upside-down and in portrait mode, while multiple accessory points enable highly creative mounting solutions. In addition, the ALEXA Mini's interchangeable lens mount can be replaced with any of those designed for the ARRI AMIRA, allowing the use of B4 video and EF mount stills lenses.

Equipped with a 4:3 sensor, automatic de-squeeze mode for anamorphic productions and frame rates of 0.75-200 fps, the ALEXA Mini records ProRes or uncompressed ARRIRAW either in-camera to CFast 2.0 cards or to a specially-designed external Codex recorder that can record image streams from up to four ALEXA Minis simultaneously -- a compelling option for multi-camera setups such as 360° plate shots. Images from the ALEXA Mini will perfectly match those from all other ALEXA cameras, making the final grade easier and quicker.

​And a look at the list of frame rates and resolutions (which are lower than the bigger ALEXA in some cases recording internally):

ARRI ALEXA Mini Frame Rates Resolutions

The coolest thing about the Mini is that nearly everything is controllable from WiFi, including the ND filters, so you can operate the entire thing remotely. 


It records internally to CFast 2.0 cards or can be tethered to a Codex (or likely other recorders):



Even though the 4K is upscaling, the quality of the sensor is such that ARRI can get away with it more than some other companies probably can. It's not really surprising that ARRI decided to come out with this model, especially since RED has been taking a lot of the work on gimabls and drones. Coming in now at about the same size and weight of the EPIC DRAGON, this ALEXA Mini gives DPs everything they wanted in the ALEXA in a smaller package. 

The pricing for the ALEXA Mini starts at €32,000, goes up to €40,000 with a full package and viewfinder. If those are translated exactly to US dollars (which we don't know if they will be), that works out to a price range of about $36,000 to $45,000 depending on options. It is scheduled to begin shipping in May 2015, with orders starting in March.
