Sony FS5 4K E-mount camcorder review at Cinema5D. And one annoying limitation reported by Newsshooter.

Cinema5D published the first impression review of the new FS5 4K E-mount camcorder:

The Sony FS5 is a well balanced package for the documentary/wedding/indie/news shooter cameraman. For those who are looking for an easy to use large sensor solution, be it “full auto mode” or “full auto focus” this is a very good alternative.
On the other hand, the advanced shooter will not feel neglected and be able to take control on most if not all camera functions in a manual way. As with most of Sony’s latest products, this one will receive a firmware update soon after its release to answer some of the shortcomings already found since the time it was announced. Sony also promised to introduce a future RAW recording capability for this camera at a later stage. Exciting.

Newsshooter pointed out one limitation of the camera

Last week we published news that the Sony FS5 won’t allow simultaneous recording of 4K internally to SD card, and externally to an external recorder at the same time. This means that anyone wanting to record to an external 4K recorder like the Atomos Shogun and at the same time internally to SD card for backup is out of luck.

There is also a Sony FS5 4K Hands on Video at Adorama Blog.

The new E-Mount 4K camcorder can be preordered in two versions:
