I really like this little camera a lot but the latitude feels a little thin to me. I want to know how far I can push it and how many stops over and under I can record before running into problems so I did this test exposing the gray card / chip chart to key and then over and under exposing by 5 stops each.

ISO 200, bracketing was done with the iris and shutter. The charts are slightly hotter in the upper center. A soft, even source like a Diva would have been better for this test but all I had at the house was a tweenie. The difference is about 3-5%, not enough to compromise the test so I'm just going to go with it.

Video file is full 1080 so watch in full screen HD to see the full effect of what's happening in the images.
