Metabones just released a much needed firmware update, which finally adds support for the Panasonic GH5. No more fiddling with the aperture button on the side of the adapter, turning on and off, and all that. Metabones firmware v2.7 for Micro Four thirds adapters and E-Mount firmware v0.56 was released earlier today also adding support for the Canon CN-E 18-80mm T4.4 L IS KAS S lens to Metabones EF mount Speed Boosters and Smart Adapters.
Servo zoom can now be controlled using the wide-tele zoom rocker on supported cameras like the JVC GY-LS300, with a touch screen interface (most Panasonic cameras), or from PlayMemories Mobile App for Sony cameras.
I updated my Metabones EF to MFT Speed Booster ULTRA 0.71x and used it on a job today (you can see a pic of my setup below) with my Canon 24-105mm f4 and can confirm that the firmware works. I was able to move throughout the zoom range, aperture, stabilisation and even AF worked.
Metabones Firmware 2.7 (for MFT) and (v0.56 for E-mount) Highlights:
An irreversible change will be made to the following products which limits the ability to downgrade to version 2.65 but not any further back, even if you have a copy of an older version of the Metabones App:
Fixed issue with SteadyShot icon on LCD display of the camera not corresponding to IS switch of Tamron 150-600/5-6.3 VC USD A011 when “choose between OIS and IBIS automatically” is chosen.
Fixed blackout issue with A7s running Time Lapse application.
Fixed issue with certain full frame lenses misidentified as cropped lenses (but the reverse may still occur).
Auto iris, servo zoom, autofocus and custom function button support for CN-E 18-80 T4.4L lens
Except Mark I/II/III and original Speed Booster!.
Compatibility fix for Contax N lenses modified by Conurus Canada on CINE Smart Adapter, CINE Speed Booster, Mark V and Speed Booster ULTRA II.
A bit if a sidetrack, but for those that care about how 180fps super-slow motion looks on the GH5, check out my super-quick and non-scientific test footage below I shot recently.
For supported Sony cameras, the Record button on the grip of the Cinema EOS CN-E 18-80mm T4.4 L IS KAS S lens can be assigned to one of more than 50 functions on the A7 series and other supported cameras.
By assigning it to the MOVIE function, the user may start/stop recording and zoom with the lens’ hand grip which is handy for a small-form-factor camera like the Sony A7R II.
Whereas a typical EF mount lens changes the iris at 1/8 stop granularity, a Cinema EOS lens permits much finer control. Metabones takes advantage of this improved precision resulting in footages in which auto iris movements are virtually imperceptible.
Autofocus is supported, but to set expectations properly, AF performance of a supported Cinema EOS lens on a non-Canon camera is significantly below that of a Cinema EOS camera (i.e. Canon C100 Mark II or C300 II) equipped with DPAF.
Important notice: Not every Cinema EOS lens supports every feature. At the time of writing only Canon CN-E 18-80 T4.4 L IS KAS S supports auto iris, autofocus and servo zoom.
