Sony F3 head to head with Alexa

The Arri Alexa is considered state of the art in digital movie cameras right now and deemed the leader in terms of dynamic range second only to (and barely) analogue film. (Not counting Red Epics HDR which does not really work the same way).
It was therefore with great interest that I watched this comparison of the Alexa with the Sony F3 that is about 1/3 of the price of the Alexa. The F3 used in these tests was equipped with the S-LOG upgrade which combined with an external recorder gives it a dynamic range of approximately 13,5 stops. That is only half a stop behind the 14 stops of the Alexa.

Arri Alexa vs. Sony F3 w/S-log vs. Canon 7D from Hello World Communications on Vimeo.

Another interesting aspect of this test is that “Hello world communications” who performed the test also put a Canon 7D side by side with the Alexa and F3.
You should really log in to Vimeo and download the full 1080p-version of the test and watch it on a great monitor instead of watching it streaming.
After watching it I must say that I am really impressed with how the F3 stands up to the Alexa. I can only say that the Alexa wins in the extreme low light scene. It is also really interesting to see how poor the resolution of the 7D is and how badly it blows out in some of the scenes.
And while I am at it. If you still have not watched the Zacuto great camera shoot out that does extensive testing of a whole bunch of single chip cameras you should!

  1. great post! Metadata are the cornerstone of 21st century post production.arri alexas

  2. We have used Arri Alexa at our production studio and used it on loads of stock footage. We've never had any complaints or alike from any clients. Its seems to blend in well.
