This is a technical post for those folks who are making videos. So if that's not you, come back next week for some less technical info. With that said... The Sony FS5 is the best camera for the money right now.
Whenever you talk about the best in a category you have to look at the competition. The Sony FS5 has been out for a while so there's a lot to compare it to. The closest comparison is the Sony FS7. It's a GREAT camera, we used one for a long time. But it's very big, it's more expensive and adding RAW costs a ton. What you get with that is a better codec but you can match it with the RAW > ProRes upgrade on the FS5 (more on that below). The Canon C200 is another option. But the non RAW codec for that is not usable for professional applications (in our opinion), plus it shoots CFast and those are expensive. Blackmagic makes some great cameras if you only need RAW but it doesn't have the flexibility.
So then you're looking at stills cameras that double as video (GH5, Sony A series, Canon 5d Mark IV, etc). When we first started we went that route. You can get some great results, but in my professional opinion a hybrid isn't a great option as your A camera. There are too many variables with audio connections, etc etc that can go wrong on set. And they don't save you that much over the FS5.
Why It's Great
So then why is the FS5 so great. Well, in my opinion it's the flexibility. There are tons of sub $4,000 used FS5 on the market. So already you're in about $3,000 less than the FS7. Throw a $500 RAW upgrade on it, add in a recorder (like $1200 new) and you've got all your bases covered. For events, quick turnarounds, small file storage, you've got the internal codec recording to cheap SD cards. For something where you need broadcast quality 10bit 4:2:2, you send the RAW out to a recorder and go to ProRes. For spots and high end work where you need RAW, you record that same RAW output as Cinema DNG and you're covered there. You have flexibility and that's the key. Throw a lens converter on it and you can use Canon, Nikon, or Sony lenses. You can scale as the project needs it.
If you're looking for a video camera right now you'll be able to cover any project needs, save some cash, and have a camera body you can sell off and keep the peripherals when you want to upgrade. To us, it's a no brainer.
