Finally a filmmaker I can relate to!
And what about, for a change, stories with no guns and no killing? Do you think it's possible? Considering that most of us will never use a gun in real life, other than at a range, and that most of us will never kill anybody or witness any killing, I'm wondering, all those gun waving characters we see in movies, who can relate to them? I personally can't. I can relate to what I've seen in Gypsy and to Naomi Watts character, but I can't relate to any idiots in The Walking Dead. Yes, let's learn how to put guns in our stories, that'll make great stories.
Frankly, if you have a limited budget, just get your hands on a Panasonic G7, you can find them for 500 bucks in the US and you can see how they look here: https://vimeo.com/search?q=panasonic+G7+
Invest in good glass for this camera that won't break the bank, probably rokinon and Voigtlander Nokton. As soon as you understand how to use light, I don't see why this camera shouldn't meet more than the minimum to capture a decent story, really! As somebody else suggested, take care of the crew and actors and stop worrying about equipment.
I'm French, and if I'm not shooting one of my project I'll be in France next summer, I can help you. I have a G7, which is basically a GH4, since sensor. IF you know how to use the G7/GH4 and grade in Davinci Resolve and use the Filmconvert, you'll be amazed at what this camera can do. I'm also falling in love with the look of the Black Magic Cinema Camera 2.5K. I have a friend who has it and frankly this is the most under rated cam right now. It's truly amazing.
You're correct. I think the GH5 is a better video camera. Now, for stills, sure, that Sony is going to be better.
Rule 1: If you are unknown, it's your first project, and you have no connections, your project will not be funded.
