Dynamic range test of the new Sony NEX-FS100. Please download the source file to see the full 1080p comparison.
Lens: Canon 50mm 1.2L
"Fotasy" EOS-NEX adapter
Conclusion: Using the settings AbelCine used in their dynamic range test (http://tinyurl.com/3krrrqv), you can see what the gamma, knee and slope settings do to your image. Which one is better? Well, there is a time and place for every one of these settings...really up to you to decide.
I also threw in a shot with the 5D Mark II using the Technicolor preset (shot is at 1,000 ISO)
