Canon R5 has proven to be an amazing camera. But sadly, it has also proven to have overheating issues. In one of his previous videos, Dan Watson used the R5 side by side with the Sony a7S, and overheating was only one of the aspects he compared. In his latest video, he has addressed this problem specifically. So, when the Canon R5 and the Sony a7S shoot side by side, which one will overheat faster? Let’s watch and see.
It’s pretty crazy just how quickly mirrorless technology has evolved, especially from Sony. They went from being a somewhat small player in the world of photography to pretty much the dominating force in the mirrorless world, and driving sales away from DSLRs.
But just how far has Sony come in those short few years since the original A7 series? In this video, Dave Dugdale picks up his old Sony A7S and compares it to his current model Sony A7RIII to find out!
The BBC is renowned for its stunning wildlife sequences. Every time they release a new wildlife series, especially one narrated by David Attenborough, the visuals are stunning. We are shown wildlife in a way we’ve never seen before. They use or invent technology that hadn’t even existed just a few years earlier. They really are on the bleeding edge of what one can achieve.
In their recently released Planet Earth 2, the crew were able to get shots that had previously been impossible by utilising new technology. Thanks to advances in thermal imaging technology, modified RED cameras, and the Sony A7S, they were able to get night time wildlife shots like nobody had ever seen before.
If you thought that the Sony A7S was weather proof think again. It obviously can’t cope even with the simplest of Lava streams.
Photographer Amanda Stevens was demoing some products at Samy’s Camera in Pasadena CA. She spotted this bitten-to-death camera. [luckily, this is not her camera]. As part of the store’s effort to convince customers to purchase an extended warranty, they have a few cameras on display that have made it to hell and back. Samy’s stuff told Amanda that this specific A7S was unfortunate enough to come across a hot lava stream.
What if Sony’s camera has so much more power internally than what they expose? We have seen Canon cameras getting a performance boost via
hacked custom firmware – Magic Lantern, so the idea is not unthinkable.
Now, youtube user Nabil Fathi claims to have hacked the Sony A7S to record 4K internally, along with providing higher bitrate and better subsampling (HDMI 10bit 422). The message was attached to a video Nabil uploaded to Youtube:
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.
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.
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 GH4, Samsung’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)
One of the things that cinematographers care about when selecting a camera for shooting is how significant is the rolling shutter effect.
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.
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.
