I don't shoot at night on X5S with an aperture of 2.8 I don't need such a test. If you need such a test, take two devices and do it.
I think this particular test was useful to many. Thanks for the feedback.
Above was the answer to your question:
brett8883 said: The test could have done at f/2.8 but if you are testing low light capability does it make sense to nerf the light gathering capability of the X5s just to match the M3? Realistically you will never use a higher ISO when you can just open...
I made a real comparison in difficult conditions and with different ISO. Look in my topic. There's a link to a video of this comparison. And in the description of the video there is a link to the source code.
