Firmware upgrade superpowers Panasonic EVA1
Panasonic has announced a firmware upgrade to its AU-EVA1 compact cinema camera that, among many improvements, will see the camera capable of recording ALL-I codecs and outputting RAW.
The free upgrade, available from the end of March 2018, means the super 35mm sensor camera will now support Panasonic ALL-Intra codecs 1 , RAW output 2 , time lapse recording as well as a new HD 422 interlaced codec 3, for TV applications.
In addition, remote operation is now possible using third party wired controllers, allowing focus and iris control for diverse lens options, as well as zoom control for Canon compact cine servo zoom.
Additionally, six Sigma ART lenses 4 are also newly supported.
LCD signal cloning to HDMI, as well as additional home screen indicators improve monitoring in the camera. To improve the workflow, Panasonic has also added the capability to output ancillary data for RAW such as time code, REC flag and also VANC metadata on SDI.
Since it’s release in late 2017, EVA1 has been used extensively in independent filmmaking, commercials, documentary and live events. Featuring a native EF and optional third-party PL mount, EVA1’s small form factor makes it ideal for gimbal and drone applications, while the colour science and dual native ISO adopted from the VariCam makes it a great B camera for bigger productions utilising the VariCam.

Housing a high-resolution 5.7K image sensor capable of rendering smooth 4K images inside a compact body, Panasonic's AU-EVA1 Compact 5.7K Super 35mm Cinema Camera is a flexible camera system ready for documentary, cinema, and live event production. The 5.7K sensor is used to super-sample internal recordings, resulting in higher resolving images with less noise and artifacting when compared to non-super-sampled recordings. Panasonic's acclaimed Dual Native ISO technology is also incorporated into this sensor. Dual Native ISO uses alternative circuitry within the sensor, rather than adding gain or shifting the gamma of the original signal output, to increase sensitivity while maintaining a high signal-to-noise ratio.
An EF lens mount at the front of the body supports a wide-range of interchangeable lenses from popular manufacturers. Directly behind the mount is an electronically controlled ND filter wheel offering, 2, 4, and 6 stops of filtration for cutting down on excess light, letting you set your lens's aperture to fit the desired aesthetic of your production. For further flexibility, the IR-cut filter is defeatable for shooting in extreme low-light situations or for creative color effects.
On the back-end, videos are recorded using 10-bit, 4:2:2 sampling for smooth gradations in subtle shades and a reduction in banding artifacts over 8-bit sampling. Bit-rates of up to 400 Mbps ensure low compression ratios that will maintain quality through an intensive post-production pipeline required by professional workflows.
Infusing high-resolution recording into a small form-factor camera body gives DPs and camera operators the flexibility to achieve cinema-grade images in spaces normally restrictive of larger camera systems. Additionally, since tactile controls and I/O connections are available on the exterior of the camera, the overall design doesn't sacrifice conventional ergonomics for traditional shooting scenarios whether operating handheld or locked down atop a tripod.
Panasonic's 5.7K sensor is at the heart of this camera. Its high resolution allows for oversampled 4K footage, resulting in sharp images with reduced aliasing and increased color fidelity over native 4K Bayer-pattern sensors. Video is recorded on widely available SD cards, providing high-quality recording on accessible, industry-standard media.
Dual Native ISO
Utilizing a process that allows the sensor to be read in a fundamentally different way, Dual Native ISO extracts more information from the sensor without affecting the image in the same way as increasing the gain or shifting the gamma. This results in the EVA1 being a camera that can switch from a standard sensitivity to a high sensitivity with minimal, if any, impact by way of image artifacting.
V-Log and V-Gamut Capture
Combining Panasonic-developed V-Log and V-Gamut, the Panasonic AU-EVA1 can capture a wide exposure latitude and represent a wide color palette. V-Log has exposure curve characteristics that are somewhat reminiscent of negative film while V-Gamut delivers a color space even larger than film. Having both of these tools enables the EVA1 to be used in production workflows for both HDR and SDR production.
