Great article and very timely. Let's be frank - HD, 2K, 4K, 8K - it is all just noise and marketing from camera companies to sell you another camera every year. Just create great content with what you have right now. If your main clients won't pay for at least the market rental cost of the latest and greatest you probably have no business buying it. You will only put yourself in more debt than you need, in normal times and especially during a time like this. Use what you have until your client asks for something new - which if everyone is honest, doesn't happen all that much because the client really doesn't care what you use for the job! They hire you for you, not for your Arri, C300 or FX9.
