Comparing Sony a7s vs Canon 6d Shutter Lag for Light Painting

img3847-2048-jpg-tyen

Eric Paré is famous for his light painting photos (here and here), most notably his process is very accurate and almost repeatable. So when he put up a post comparing Canon’s EOS 6D and Sony ‘s a7S I thought the results were quite interesting and worth sharing.

Eric uses a process where he shoots in the dark for 1 second and ‘light paints’ during that second. This process is so fine tuned that it serves as quite a good basis for comparing the camera in a real world scenario.

Obviously both cameras produce a very good image but they are not identical and the differences are quite interesting, especially on shutter lag. I was expecting the Sony to win hands down, but the Canon took an obvious lead there.

‘Refuge’ is the First Narrative Film Ever to Be Exclusively Lit by Moonlight; Recorded with Sony’s a7S

Refuge

The Sony a7S is well known for the quality of its groundbreaking high-ISO video, with an endless amount of test videos posted online.

Back in September of last year one video rose above the rest when Carbon Studios released a short film lit entirely by moonlight, aptly named ‘Moonlight’.

Blown away by the video, a director by the name of Sam Shapson said he “felt compelled to apply what they’d accomplished to narrative”, and the result is the first narrative film ever to be exclusively lit by moonlight. Of course this film was also recorded with the a7S.

Unlike ‘Moonlight’, however, which was mostly recorded using ISO 12,800 and just two scenes used settings of up to 32,000, ‘Refuge’ was shot at ISO 51,200.

The resulting video is, unsurprisingly, far from perfect, but the camera’s low light capabilities are absolutely incredible.

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)

Rolling Shutter: Sony A7s Compare to Other Major Players; Meh…

One of the things that cinematographers care about when selecting a camera for shooting is how significant is the rolling shutter effect.

as7-rolling-sutter-03

Rolling Shutter is a ‘side effect where vertical lines in the real universe appear as diagonal lines ‘on film’. For example it smears buildings when shot out of a moving car or create  a jello effect when the shooting camera is unstable, we explained this in length in this post.

The good guys at Cinema5D took the crown challenger – Sony A7S with its remarkable low light performance and put it to the test against some of the other leading video cameras in the market: Arri Amira, Panasonic GH4, (Canon C300), Canon 5D mark III and Canon 1D C. 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.
