While the full-frame 1080p/4K a7S from Sony is proving to be an absolute beast in low-light situations, it's far more than just a night-shooting camera. Besides resolving what looks like a very solid 1080p image (an external recorder is required for 4K), it's also got some pretty fantastic dynamic range. How good? Well the folks over at cinema5D took the camera for a spin, and measured it at over 14 stops, right next to the ARRI AMIRA, which uses the same sensor as the even higher-end ALEXA, which is being used on tons of Hollywood and indie features.
If you missed it, here is how good the camera is in low-light (courtesy of Philip Bloom):
Here we tested usable dynamic range of the given cameras. With 14.1 stops the usable dynamic range of the A7S comes surprisingly close to the Arri Amira with its legendary Alexa sensor (see our full review here).
This is an extremely good dynamic range rating and is fascinating considering that the A7S is available at a fraction of the Amira’s price and is also in a completely different weight and size class. While the Amira will outperform the A7S in other tests, the dynamic range is a very important attribute to consider when working with a camera.
The Canon cameras come in at 11-12 stops of usable dynamic range. This is still a very strong dynamic range rating, but in comparison to the A7S the Canon’s are way behind.
The Panasonic GH4 had the worst dynamic range in our test. This is in line with the rather videoish look and contrasty colors we can subjectively observe.
Some ungraded S-Log2 footage from ROMAN | LEGION, which is the profile used in the dynamic range test above:
It's also worth noting that some of Sony's press materials mentioned 15.3 stops of dynamic range, here's the Amazon listing:
Presenting the world’s smallest and lightest1 full frame interchangeable lens camera. With a groundbreaking 35mm large pixel image sensor rated at 15.3-stops of dynamic range and an ISO 409,600 sensitivity2, the α7S reveals astonishing detail and color even in the dead of night. Video excels with Full Pixel Readout, a 4K-optimized sensor and uncompressed 4K output. Fast, intelligent autofocus completes the picture.
While another testing site, DxOMark, measured the camera at 13.2 stops, they are only measuring the RAW photo capabilities, so it's possible that Sony is really pushing the sensor in video mode to get the most out of the 8-bits of video that are there. The processing in the camera combined with the S-Log2 looks like a lot of detail that might normally be lost in shadows is being preserved.
No camera is perfect, and for the price to be this low, it can't have absolutely everything. For example, the S-Log2 mode has a base ISO of 3200 (not a typo). So even though you can get incredible dynamic range out of the camera, it's going to require a bit of ND filtration to squeeze every ounce of it -- though it should be mentioned that there are other picture profiles on the camera that also get very good results. Rolling shutter seems to be at the higher end of DSLRs as well, though it's not quite as bad in APS-C mode:
For a $2,500 camera with high frame rates to be producing sharp 1080p and dynamic range close to an ARRI is quite a feat. The Blackmagic Cinema Camera and Pocket Cinema Camera have very high dynamic range as well, though they lack high frame rates and don't have quite the impressive low-light abilities the Sony cam does. Again, no camera in this price range is perfect, and all of them, from the Pocket to the a7S, can produce excellent results when used to the best of their abilities.
If you grew up or listened to pop music anywhere within arms reach of the 90s and early aughts, you're likely to have some semblance of unavoidable knowledge of Jennifer "J.Lo" Lopez's love life. It seemed like paparazzi and tabloid culture was at an all-time high around then, and luckily (hopefully?) has calmed down at least a little bit as we've all matured in our media literacy (in some ways better than others).
As a response after a 10 year hiatus from music, J.Lo recently released her music film and album This is Me... Now . It's both an answer to that particularly public time in her very successful career and life, as well as a love letter to her voice as an artist.
The result is an hour long conceptual music video-like film cataloguing her love life and growth through good ol' visual metaphor and dance a la the likes of Lemonade (unavoidable reference, though now cliche). It's very cool and stylish and a true testament of artistic expression that's worth a watch for anyone ranging from J.Lo diehards to casual fans. I'm a punk guy with little knowledge of J.Lo past her hits, and I had fun!
But we're not here to talk about that today. While filming This is Me... Now, a separate documentary was film simultaneously of the filmmaking process of the music film, The Greatest Love Story Never Told. (Phew).
The results are a charming and vulnerable look into an already vulnerable project. For our audience here at No Film School, it also offers quite an interesting voyeuristic view on how a production of this magnitude is made (and how it might be particularly hard without the J.Lo money of it all). And, lastly, lucky for us, we got to speak with the director of the documentary Jason Bergh on the process of crafting J.Lo's Heart of Darkness.
If you're still with me after that Russian doll of an introduction, please enjoy our chat with Jason where he gives us some insight into his own musical origins, as well as the ever important advice to value your crew no matter what role they pay.

The Musical Origins of Jason Bergh

"Yeah, I think for me, music is such a important part of my life.
I was lucky I had parents that played incredible music in the house and for me, introduced me to incredible music from all over the world kind of growing up. So music has always been a big part of me, and also it's a huge part of film and filmmaking and it helps set tones and evoke emotions.
And so I'm obsessed with music, and when I was younger—18, 19 years old—I was lucky enough to work for this magazine in New York called The Fridge Magazine, and we used to put on music festivals where we'd bring action sports and skateboarding festivals with musicians. We'd go up from Brooklyn to Vermont and we'd put together festivals.
And so it was very much documenting musicians. I think I shot an Eminem show, I think before even his first record came out on stage at Mount Snow in Vermont in a warehouse. So I've always just been very drawn to musicians. The process, the creativity behind it, the performance, just from writing a record to performing a record and everything in between has just been fascinating to me.
I've been shooting for, I mean, I've had a camera in my hand since I was probably 12 years old in some way, shape. or form.
Whether it's an old Canon 81 shooting stills and developing the film. And I had a dark room in my basement, kind of a makeshift dark room, and my dad had an enlarger from when he was younger. I remember he basically, he just kind of saw that I was interested in taking photos and telling stories and he was like, well, I think it'd be really cool for you learn how to process this film and there's so many different things and aspects that you can do when you process film, the dodging, the burning, the exposures, and all this.
I think that's where my obsession for filmmaking really begun is just understanding there's a whole process here, and that was kind of my entree into it."
The Camera Kit for 'The Greatest Love Story Never Told'
"So camera wise, for a lot of the stuff that was happening during the filming of [Jennifer Lopez's] movie, This is Me Now, we had two Sony Venices. They were rigged up on easy rigs, they get kind of heavy. And then I had the vintage Cooke S4 lenses, and we stuck a lot on, there's a lot of stuff on the 75, I believe the 35 or somewhere in that 35 range might be a 37 for the S4s.
I love doing that. I love showing the scope of where we are and then mixing that with a closeup kind of shot so you understand the environment that you're in. And then the next shot you see is kind of the intimate shot that's right there and you're brought into that. And our DP, Alex Paul, is incredible, who I love, who I've worked with in the past, we talked a lot about that when we were coming up.
I wanted these big bird's eye shots, but these big bird's eye shots aren't on cranes. Literally going to the GE teams on the big movie, I'm like, 'Hey, do you guys have a ladder? Can we borrow a ladder?'
They're like, 'yeah, take a ladder.' So we're grabbing ladders, we're running, putting them into places, and then we're climbing up on top of the ladders with a sandbag or of sorts that's on top of the ladder and you got the camera on top of it and micro force zooms kind of going in.
That's tough, right? Because you got to get those shots, but you don't have a lot of time because when you're making docs, it's not like you could say, 'Hey, can you redo that?' You got to be able to be able to switch, get the micro force off and get your primes back on and be able to switch pretty fast. And that comes from the incredible assistant cameras, first acs, second acs, and third acs that were just on point. And we knew we got to switch, we're switch swinging the lens, boom, got, we already say, okay, how fast can we swing the lens?
And sometimes we'd be like, all right, this one's going to be like 45 seconds, or this one's going to be a minute and a half, or, oh, I can swing this one in 10 seconds. And then you kind of look and you're like, okay, well I can get this shot. Then you got to kind of plan, okay, if this lens is going to take this long to switch, you got to replan where you are and what you're doing based on that."
Jason Bergh on the Importance of Respecting Your Crew

"I mean, we're nothing about crew. Crew is the heartbeat of any project that you're on. Every single person from the PA to the executive producers, everybody needs to be respected and needs to be treated the way that you would want to be treated.
I'm so lucky because we had such a wonderful family-like crew on this, and I was reading a post at someone the Post the other day, and Natalie, one of our first acs was just like, I'm miss hearing Jason's banter on the comms because you also, when you're on the comms, sometimes it's intense and I have a tendency to just throw a joke in there or just say, how lucky are we to be doing what we're doing just to keep everyone, it gets intense when you're in these scenes and you need to break through the intensity a little bit throughout the day.
We all were a PA at some point in our career and PAs are the future of our business, and they are there learning and they're there trying to soak in as much knowledge as they possibly can, and they're on their come up in a business that's already tough. And that's why you try to just, at least for me, I try to when I'm in control and I try to fix the things that I saw were broken when I was coming in."
The Ebb and Flow of Shooting a Doc about a Shoot
"There was tons of meetings beforehand, understanding what was happening and what was taking place as far as her making her film This is Me Now.
We did a ton of research. We read the scripts, we talk to people, and we try to figure out what's happening. And then on the day before, every day at night before, I'll reread the sides and really just try to understand what's happening on that specific day. And then that's when I'll make the plan with a DP will come in the morning and say, 'okay, well, let's concentrate on these lenses for the day, or this is how we're going to move, or we got rain coming today. How do we play that into the story? And so we just going with the flow, right?'
Because again, with docs, you can't ask to do things twice, so you have to be ready and go with the flow. So yes, we do plan, but a lot of it is found during the day and you got to be kind of open as a filmmaker to be able to just let things find you while you're doing what you're doing throughout the day, but you also have to search for it and look for it. I hope that makes sense. It's a combination of things.
Those are the documentaries that I learned when things happen and phone call happens and I changes the trajectory of your story, and then now you got to go and follow that kind of story as that's happening. And that's not scripted. You can't script that. That's just real life happening, and you have to be so aware and so in tune to what's going on that you are able to pivot.
That's the difference I think with docs is that things can change in a matter of a second, and if you're not prepared and always ready, and sometimes I come home at the end of the night and literally I make it to my bed and I'm fully clothed and I'll just sleep. I've been thinking so hard all day and trying to be ahead of it. You always got to be steps ahead and your preparation and how you get down. So yeah, I hope that answers the question.
Yeah, I mean, we had a fantastic editorial team led by Lindsay Utz, Grace Zahrah, Lenny Masina, Jenn Horvath, Elizabeth Maria Barrett. They are the best of the best. We basically, we shot everything and yes, I don't look too much at dailies because I'm still obsessive of what I'm getting throughout the day and taking notes. I'm always taking notes throughout the day of things that stood out to me."
Jason's Advice to Future Filmmakers
Jason Bergh
"I think advice for filmmakers is always based on that specific filmmaker that asks me just based on who they are and what they're doing and what they want to do.
But I think for me, and it's funny that we're on No Film School, but for me, and again, this advice doesn't go to everyone, but from my piece of advice is don't go to film school and get a business degree or some sort of business degree because you as filmmakers, we are our own business and it doesn't matter if we work in a company, it doesn't matter if we work at a production company or an agency or whatever.
As filmmakers, we are our own business and we need to know how to operate our business or we get taken advantage of. And so you can learn film as a PA and especially now with YouTube and all of the things, you can learn all the things on set. I think being a PA for a year, you can learn a lot, probably more than a year in college as far as going to film school.
Yeah, film school right now, I think you could look at the Chapman's and the NYU's amazing institutions, but they're 90 grand a year. To me, it's like if you have someone that's going to pay 90 grand a year, I would say, well take that 90 grand and put that into a budget for a film, and you can make a film for $90,000.
You can do it. People do it all the time."
