The Panasonic 5.7K Super 35mm cinema camera received firmware update v1.12 today and it's good news for shooters using Sigma Art optics. With the release, the AU-EVA1 now supports Sigma EF lenses 12-24mm F4 DG HSM,  24-70mm F2.8 DG OS HSM, 14mm F1.8 DG HSM, 30mm F1.4 DC HSM, 85mm F1.4 DG HSM, and 135mm F1.8 DG HSM. The update also corrected abnormal vales in iris and zoom which happened on rare occasions. 

If this is the first you're hearing about AU-EVA1, the handheld cinema camera supports high frame rate recording of 4K 60 fps and 2K 240 fps. Its 5.7K Super 35mm image sensor can record 10-bit 4:2:2 images with a wide 14-stop dynamic range. For those in need of low light performance, Dual Native ISO is available at 800 and 2500 for low noise workflows. Similar to Panasonic's higher-end VariCam cameras, this compact version supports V-Log gamma and a wide-color gamut V-Gamut colorimetry for the "VariCam look." You can read our full review here.  

Additionally, Panasonic released a series of nine educational videos highlighting the specs and functionality of the AU-EVA1. Short and to the point, they cover its sensor, modular design, focus, inputs, image stabilization, and the aforementioned Dual Native ISO, among others. 


The 5.7K sensor has about two times the number of photosites of a 4K sensor providing more image detail. When using the single designed sensor at 5.7K to shoot 4K, it sees 2000 line pairs to produce a higher quality 4K image. 

Dual Native ISO 

Originally found on the VariCam line, Dual Native ISO touts two pathways at 800 and 2500 to draw information from the sensor to reduce noise. The AU-EVA1 can capture 14 stops of dynamic range allowing the native 800 ISO to be lowered to 200 and raised to 2000 ISO while 2500 can drop to 1000 or up to 25,600 ISO. 

Image Stabilization 

The AU-EVA1 supplies power to EF mount lenses with built-in optical image stabilization through the lens mount directly on the camera. For other lenses, it offers electronic image stabilization over optical. This process entails cropping the sensor slightly so the camera can move the recording window to compensate for movement. 

You can zip through all nine videos in less than 15 minutes to visually learn the basics of the AU-EVA1. Find the playlist here.

To update the firmware, copy the software to an SD memory card and insert it into the cinema camera. The download can be found here
