4k UltraHD Video Camera Showdown: a7S, GH4 and NX1 Compared

We recently did a quick poll here on the blog and if our audience is any indication shooting 4K video is not there yet. But early adopters (manufacturer and shooters alike) are starting to use 4K capable cameras and it is time to start comparing some of the consumer/prosumer models out there.

In this showdown Tony Northrup compares three models: Panasonic’s GH4Samsung’s NX1 and Sony’s a7S connected to an Atomos Shogun (to draw full 4K out). The team compared Dynamic range, focus tracking, high iso, impact on computer performance and more. (As a side note, price for 4K is quite difference as well: $1,500 for the GH4, $1,300 for the NX1 and $4,500 for the a7S and shotgun combined)

Sadly it did not do all that well.

Sony’s a7S Tested in the Middle of the Night, Yielding Impressive Results

With the sensitivity of the Sony a7S reaching up to an ISO of 409600, the camera itself has had some pretty high expectations to live up to. Just recently, Photographer Yosh Enatsu took the a7S out for a test run and uploaded some results showing what the camera truly can be capable of. Considering the a7S doesn’t have its own internal 4K codec, the shots were done through a setup utilizing an external Blackmagic converter. Filmed in the middle of the night, the final two videos we see paint an impressive image of what the a7S can do.
