A test of the Sony A7 4K mirrorless camera under the moonlight at Big Sur

The camera that a number of reviewers have called the very best for video among the ultra HD capable cameras released in 2014, the SonyAlpha a7S mirrorless camera, offers a very robust consumer grade 4K video recording and powerful photography package rolled into one compact and relatively affordable device.

Furthermore, it also seems to have some truly excellent low light capabilities that are definitely worth checking out for such an affordable machine. And to demonstrate just what kind of features we’re talking about, we bring you to the video recording test recently conducted by photographer Justin Majeczky at Big Sur, California in the middle of the night as a demonstration of how the camera performs under moonlight conditions.

The video at the bottom of this post was captured in 4K ultra HD resolution at the camera’s maximum frame rate of 24p and an ISO of 40,000.

Majeczky also explained to petapixel.com that he was using a Canon 24mm f/1.4, 50mm f/1.2 and an 85mm f/1.2 with the lenses wide open during the entire filming sequence.

According to Majeczky, the specific settings were “f/1.4 or f/1.2, 40,000 ISO, 1/25th, 24p 4K UHD, Slog2, curves + saturation + neat video”.

Furthermore, the professional photographer brought along an Atomos Shogun 4K HDMI/12G-SDI Recorder for holding the camera in position during the mobile shooting.

According to Majeczky, the results of the camera were very impressive on the whole and the Alpha a7 manages to be an excellent solution for 4K video capture in general and for low-light shooting abilities in particular. It does this job even better with the assistance of the Atomos Shogun. However, he also explained that the A7 isn’t perfect for every production type with its IRE values of 40 or less and works best if you’re looking for a distinctly night time look to your video.

Either way, judge for yourself, check out Majeczky’s video below:

    Uh, the camera won’t record 4K without this external recorder. It’s definitely not “holding the camera” Writer has no clue, obviously.

    Ha ha! true! Being a “professional photographer” myself, I always carry my Atomos Shogun 4K HDMI/12G-SDI Recorder with me.. In the case of a random situation arises to hold a camera in place. I never would figure such a poor and cheapskate design of requiring an external device to capture from the HDMI port. (Like the old days when the 5D big firmware release of uncompressed video from the HDMI port… whoa!!! ) Too bad I only bought the Shogun 4K HDMI to carry around and hope somewhere a camera needs to be held in place. We might have been able to hookup up to the Sony A7’s port and record the video, but I never even charged it up, and the cables are still unwrapped in the packaging.
