Cinematography : Which is a better camera? by Kensly Fresh Agenor

I've been been pro-Canon for a while, but the new Sony A7s2 looks like it has some great features. Mirrorless, 120fps @ 1080p, FullFrame sensor speaks volumes to me. Good price too. I can't wait to try it out.

I've used the 5D and 7D when the DSLR craze hit but frankly there is no reason to use one any more. They are more trouble than they are worth. When I started my own company a few years ago I relied mainly on a hot rodded Panasonic GH2. I like the M4/3 platform. The GH4 is interesting to me for that reason but I started using Blackmagic cameras in Feb 2014 when I got my BMPC 4k. Shortly after that I bought a BMPCC and it has become a favorite. Both of them have their pros and cons but the ability to shoot raw 1080 HD with 13 stops of latitude on the BMPCC is a great thing. The color science behind the image in that camera is very nice as well.

I have been one of those guys who focus on storytelling more than the camera, but if I were you, I would buy the GH4. It's a good, standard 4k camera that gets the job done.

Than you guys. I been shooting on the 7D for 3 years now and I love it. i guess i love it since it's all i know when I started 3 years ago. I have pushed it to its limit and been using ML Raw on it for over a year. Like @Jacob mentioned, it's more about telling the story especially if you have decent gear. @Dave the BMPCC and the BMPC was one of my choices awhile back. I'm still thinking about going getting one. I love editing in DaVinci Resolve and i think it would be great to own one.

I'm a BMPC4K user and I love using the BMPC for many story telling aspects, such as Films, commercials, documentaries and etc... I've used the GH4 as well. The cameras you listed are all good cameras. They all have their pros and cons. But I could recommend you a camera all day, but it all depends on what camera you are willing to learn and push boundaries with. The BMPC has super great quality and working with Davinci is a mega plus. The compact of the GH4 is great for its price tags. And the A7S is great for all around. But my recommendation is to rent each one at a time. See which one you like best, before you buy your final choice of camera. Happy Shooting!

For the moment I still use the Sony NEX FS100, but if I have to choose one from the list I pick the A7SII.

3 different cameras. Apples oranges and tennis balls.

As Royce says, these cameras are all different. Every camera has strengths and weaknesses. If you are buying a camera, it depends on what types of projects you mostly shoot. If you rent cameras (like I do most of the time) then it depends on the technical, aesthetic, and budgetary parameters of each project. Without going into great detail about each camera's specs, I'll mention a few strengths and weaknesses to consider. BMPCC: Pros: Very good dynamic range, ability to shoot RAW for optimum grading potential. Cons: Doesn't perform very well with high ISO's and low light, RAW is uncompressed, so file sizes are huge so not very practical for many types of professional projects. GH4: Pros: nice set of features for lower cost such as internal 4K and high speed recording internally. Cons: Doesn't perform well with high ISO's and low light, Dynamic range is on the lower side. A7S II: Pros: The best high ISO low light camera by far, excellent dynamic range especially with S-log, reasonable internal card file sizes for lower storage and ease of use (can get better color space and recording bit rate by using an external recorder), large sensor enables shallow DOF. Cons: Not a very robust codec for internal 4K recording (needs external recorder to get maximum potential), high speed recording is cropped by a 2.1 x factor. Of course there are many more features to compare and consider. The good news is that one can achieve great results from all of these cameras if one can play to strengths and avoid or hide weaknesses. Many young filmmakers get far too hung up on camera choices in my opinion. It's much more important to focus on developing the skills and craft of cinematography. Great camera work and imaginative lighting can be achieved with nearly any camera. And as Jacob says, great storytelling trumps all.
