The Sony PXW-FS7 has been quite the hit for Sony, who managed to pack some serious professional features like 4K XAVC recording up to 60p, in conjunction with broadcast favourite codecs like ProRes (with the XDCA-FS7 extension unit) and MPEG-2 HD 422 at 50Mb/s in addition to 4K/2K Raw recording via compatible recorders and slow-motion up to 180fps in camera at a very aggressive sub £8K price point.
The native Sony E-mount present on the FS7 allows users to adapt almost any other lens out there including the highly desirable and popular Canon EF optics. However the electronic aperture control via the Metabones adapters wasn't always as smooth as it should be - with users reporting flickering during aperture changes.
The latest firmware update for the Smart Adapter EF to E Mark IV from Metabones address those issues, and is a welcomed improvement for all those FS7 shooters out there using Canon EF lenses with their 4K Sony XDCAM camera.
See more details on the improvements in the latest firmware V0.41 for the Smart Adapter Mark IV below.

User may choose between lens OIS and IBIS using the lens’ IS switch (except for some Tamron lenses). If the lens’ IS switch is ON, lens OIS is used and IBIS is turned off automatically.
