Hi all, I recently was shooting on BMCC and decided to make comparison of BMCC vs 50D.
So I decided to evaluate the usable DR of both cameras.
This is not a scientific test -- just practical approach.
I was shooting both scenes in a ETTR way (without ETTR module), so that the whites are nearly overexposed.
Then I tried to push the shadows and see how much that can go until you have unacceptable noise (purely in my opinion)
I'm pretty sure that someone can make more sense from these tests, so welcome!
BMCC was shot at ISO 800.
I decided to shoot 50D at ISO 400. On the one hand, I wanted their ISOs somehow to match. On the other hand, ISO 800 of 50D would be too unfair to 50D, being a no low-light king.
The same 17-50 2.8 lens was used.

50D. Shot ETTR. ISO 400. Pushed shadows. No sharpening or noise reduction. ACR 6.0

BMCC. Shot ETTR. ISO 800. Pushed shadows. No sharpening or noise reduction. ACR 6.0

100% Crop: BMCC and 50D - The darkest shadows in the scene and my personal view of acceptable noise.
CONCLUSION: Based on the eyedropper tool info in the shadows I estimate that BMCC is 1 stop wider in its Dynamic Range.
As I said, this is a brief non-scientific test. Don't shoot me based on this. Any reasonable comments are welcome.
And yes, the original RAW files are found here:
