Yes, but like most popular LUTs (I’m thinking Osiris here), it can make crappy locations or production design look purposefully done. It has a time and place but it’s definitely rent-a-style.
When you price out a similar Alexa Mini or Red package it gets to be somewhere like that. I can't imagine anybody would put up the investment without seeing the if the camera gains any traction in the market but let's see. If I were Sony I would've tried to compete with the Varicam LT on price and tackle the market like that.
The only thing that kills me about this and the C200 are a lack of in camera 4k 60 in the beefier codec (I believe the EVA1 only does this at 420). When we produce our doc shows with FS7s, we shoot in 4k 60 about half the time. The fact that cameras 3 years newer aren't doing that yet is either ridiculous or really says something about what Sony achieved with the FS7.
This is a tough question. Since you mentioned you don't have other accessories, I would really consider getting a proper video tripod as a part of your budget (as basic as that concept sounds, it escapes a lot of people.) Don't blow your money but make sure it has a bowl head and can balance your camera. Used is good if you know what you want.
Lenses aren't easy and I don't particularly like the Rokinon/Samyang series personally (I had a 35mm break without much of a fall.) Get a cheap 50 to start (vintage or nifty 50). Get another more versatile lens, the previously discussed Sigma 18-35 is a lot of fun and great for handheld. My personal favorite Canon L (that we still use in mostly cinema glass kit) is the 100mm 2.8L macro. It's a killer portrait lens and the macro is really useful for the no-budget filmmaker.
That's close to $2000 and gets you through the day. Seriously don't forget the tripod.
Rent another RED Camera first, especially as your first video camera.
See if the rental company will also let you hire someone to operate so you can get some understanding of how it works. Take it out on a shoot and then make a decision.
Also what somebody mentioned about pulling stills is exactly my experience, it's generally unusable unless you're shooting high-speed, which brings about another set of complications. YMMV but I wouldn't plan on it.
Honestly, it's likely that neither will work for you better than an FS5. Haven't used the Ursa Mini, but our FS7 is a really amazing little camera. We use it in heavy doc and commercial production all the time and it's by far the best camera I've ever owned (coming from a C300.) We own and love the new A7S, but the best thing about it besides the low-light party trick is that the image looks a whole hell of a lot like an FS7.
A more ergonomic FS7 (albeit with a lighter codec) sounds like an amazing deal for someone in your price range.
The Ursa Mini might end up with a beautiful image but Blackmagic always pushes DR over low-light and that will limit the flexibility of the camera considerably. FS7/FS5 aren't low-light monsters, but you can comfortably shoot 3200 and up if you need it.
As for FS5 vs A7s, yes - the image will likely end up being quite similar - but consider how much you might want a proper handling camera with actual audio inputs and the like.
