2015 was definitely a year of video for everyone, especially with Sony and Canon releasing the A7RII and 5D SR which made (semi)pro video available at a pretty low price point (assuming you consider 3K low).
If you think that 3k is too high, here is some perspective for you. The other side of the production continuum has cameras where 2-3 thousand dollars can be their daily rent fee. Of course there is a reason for that, and those cameras provide superior image quality (usually at low light), dynamic range and bit depth, as well as other non-quality related features.
To get your GAS going cinematographers Tom Fletcher and Gary Adcock compiled a list of all available production cameras for 2015. Starting with the Alexa 65 which shot parts of The Revenant through the Sony F65 (shot Tomorrowland) and Red Epic Dragon (The Martian) all the way to the affordable Canon C300.
The chart includes Sensor Size, ISO,Dynamic Range, Frame Rates, Pixel Resolution, Bit Depth,Data size (Per Min), Weight and Daily Rental Price among the data collected. On the other hand, the chart is not a test-and-result chart, but rather a compilation of stats gathered by interviewing photographers, colorists and manufacturers. As the team notes, there are more than numbers to decide on a camera:
Please portions of this chart are subjective. This is not scientifically tested and collected data. We have sincerely tried to assemble accurate information to share with the industry. Our goal is to help producers make an educated decision in a rapidly changing camera landscape – that said – numbers do not tell the whole story – look at the images and consult your cinematographer
