Kinefinity MAVO LF - In Depth (3 / 3)

The MAVO LF is Kinefinity's current flagship.

Power outputs

The KineBack-W has two 12V@1A DC D-type tap outputs (one on each side) that can be used to power external monitors, wireless transmitters and other accessories.




SYNC (3D/VR ready)

Due to its light and small form factor the MAVO LF can be used to create a 3D or VR/360° system. The 3D/SYNC allows a real synchronization of CMOS sensors.
For a 3D system, both MAVO cameras must be equipped with KineBack-Ws and SYNC cables connecting the SYNC connectors of both KineBack-Ws. No additional software license has to be purchased.

For a synchronous system with more than two cameras (more than two) all TERRA cameras must be equipped with KineBACK. One KineSYNC device can synchronize up to eight MAVO LF cameras (one master camera and seven slave cameras).

Audio without KineBack-W

Without KineBack-W the audio recording is very limited. The camera body only has an internal microphone or the possibility to connect an external 3.5 mm microphone. The sound quality of the camera-internal microphone is not good and you can only use it for an emergency audio track.

Anamorphic recordings

The MAVO LF offers a variety of anamorphic recording options. For full-frame anamorphic shooting, you can shoot 5,376×3,984 or 6:5 4,864×3,984 in 4:3 (the height of the active area is 24 mm). The rectified image coming from the MAVO LF is taken in 65mm format with FF anamorphic lenses mounted. For the S35 anamorphic lens: both 4:3 4,096×3,072 and 1:1 3,072×3,072 (the height of the active area is 18.3 mm) can produce up to 50 frames per second, bearing in mind that anamorphic lenses are expensive both to rent and to buy.

The camera also has options for monitoring, depending on the type of anamorphic lens used. The options are:

  • 1.25
  • 1.33
  • 1.5
  • 1.75
  • 2
  • 0.5


Image quality

The MAVO LF has a very good color reproduction and it is very easy to take nice pictures with the camera. And that without much post-processing (unless you shoot in RAW format). 
The camera can create a slight aliasing. This could be a problem, depending on what you shoot.
In front of the CMOS sensor is an OLPF (Optical Low Pass Filter) called FF1, which Kinefinity claims prevents stronger aliasing. A "stronger" OLPF called FF3 is optionally available.


The OLPF may block high frame rates that may cause image artifacts when shooting in certain situations. The sharpness of recorded images is reduced because the OLPF blocks high frame rates. In accordance with Kinefinity, the optical characteristics of your OLPF have been carefully tuned to ensure a perfect match between the image content and the avoidance of aliasing artifacts in the composition. With a "weaker" OLPF, image sharpness is better, while with a "stronger" OLPF, aliasing is more strongly suppressed. 

Resolution & Detail

The MAVO LF resolves fine details well. Images appear organic and not oversharpened.
Skin tones and colours
The ColorScience of the MAVO LF has been improved once again. The colors look natural and pleasant. With the skin tones a minimal shift towards magenta can be observed, but this is done in a pleasant way and only minimally.

Rolling shutter

Like most other CMOS sensor cameras, the MAVO LF suffers from some rolling shutter problems. However, these are only really disturbing in a few cases. It really depends on what you are recording, for example if there is a lot of movement and/or strong vertical lines in the image.

ISO and EI

The ISO range is between ISO250 and ISO16.000. The MAVO LF can be used in both ISO and EI mode. The standard ISO values are 800 and 5,120.
If you set the MAVO LF to EI mode, the change of the nominal EI value affects the highlight and shadow stops. The image brightness is adjusted by the digital gain while the analog gain of the CMOS image sensors remains unchanged.

Highlights

Kinefinity recommends that if you want the highlights to contain maximum detail, set them to level +4 above medium gray. This will not affect the contrast range. Only the location on the exposure curve to which the highlights are assigned changes. This only works in ISO mode.

Image noise

Kinefinity cameras have not been known to be particularly bright. But the MAVO LF is better and stands up to this assumption.
With the MAVO S35, the limit was around ISO 1,600/2,560, whereas with the MAVO LF you can definitely go up to ISO 6,400.

Post-processing

If you want to make RAW recordings, you need to be prepared not only for the huge amounts of data, but also for the necessary post-processing. Currently the camera does not have KineRAW 2.0, as I mentioned earlier, and if you want to record RAW, you can only do so in Cinema DNG.
In the future, however, Kinefinity will rely on ProRes RAW.

Selected accessories

The MAVO LF is designed to be compatible with TERRA accessories such as the KineBACK-W, which provides SDI monitoring, XLR 48V audio, V-Mount plate, regulated DC output, time code synchronization and 3D synchronization in one module. It also supports the Darktower platform, which enables wireless video and lens control. For monitoring, Kinefinity features the KineMON, a full HD monitor 5? that is powered and feeds video through a single cable.

There is also a SideGrip, which allows the MAVO to be controlled and powered by a GripBAT 45Wh (BP-U30 compatible) battery, which, according to Kinefinity, provides more than one hour of operation. There is also a KineBAT 120Wh, a compact V-Mount battery that provides additional runtimes.


The KineKIT-TERRA from Movcam is a complete shoulder mount kit with base plate, top plate, handle, handle with stop/start trigger and much more. This kit is not bad, but you still have to use a relatively heavy battery together with the KineBack-W to get a reasonable balance.
The problem with this setup is that you can't easily control the camera because the SideGrip can't be removed from the camera body, and if you're using a Canon EF lens, you can only control the aperture with the side knob or the knob on the SideGrip. Both are very difficult to reach when you carry the camera on your shoulder.
