I'm a DP working out of Central America and most of my work is high-end commercials in the region. I do some eventual documentaries, music videos, short films, etc, but my bread and butter is commercial work. So far, I've been renting gear out and mostly shooting on Arri Alexa Plus and RED Epic MX. I do not own any important personal gear.
There are a couple of jobs coming up and I have the opportunity to invest about $20k on a camera package. 50% of the investment would be paid off within the next 2-3 months. So far, I've been thinking about purchasing a used Arri AMIRA. I like the fact that you can shoot 3.4k RAW, am a huge fan of ARRI's color science and the sensor's dynamic range. My main concern is that this camera was released six years ago and sensor technology is quickly evolving.
I've also been looking at the new Sony FX9 as an option or even spending a little more money and going for a RED GEMINI (just because of native resolution and trying to future proof the investment).
My gut keeps telling to go with the AMIRA, but I would really like to hear other opinions and ideas!
