On April 6, 2014, Sony proudly announced its 4K/Ultra HD video camera in a still camera body: the a7S. The Panasonic GH4
had been announced two months prior, and the
promise of 3840 x 2160 video had filmmakers like
myself casting aside the Canon 5D Mark III.
But Sony’s marketing department had jumped
ahead of the Sony engineers. You see, the a7S
can’t record 4K video to a memory card—it
requires a separate field recorder that didn’t exist
until the very end of 2014. Now that the Atomos
Shogun and Convergent Design Odyssey7Q+ are
available, we can finally experience full-frame, low-
light 4K video with the a7S. It was worth the wait.

recorders like the Atomos

With external recorders now available, Sony’s full-frame
mirrorless can finally record 4K video. Is it worth it?
