Yep still calling BS...you all told me that same lighting same f/stop same exposure = same shutter speed...now the excuses are starting to concern me....something ain't right...
This is what you folks just said to do with the EM5 and Nex-7 that you would like to see valid test...here they are in exact same lighting, better than we could do at home and you are still making excuses...
So you all are telling me you would believe a test done by a private party as opposed to a consistent light source with same subject...lol...the Kings New Clothes....
and the Nex-7 is the fastest shutter of all so the rest of the camera manufacturer's must be deceiving everyone with ISO?...oops two of those are Sony's!
I called BS for good reason...
Calling BS is primitive - it is also very troll like. But I'll give you the benefit of the doubt, at least you put in lots of effort.
I was typing a longer explanation, but I will shorten it: the EM-5 uses double the shutter time of the Nex-7. Given that the EM-5 and Nex-7 have almost identical pixel site sizes (see my earlier post), meaning similar SNR ratios, their light response, under these controlled test-conditions - should be identical. But we see that the EM-5 is a full stop slower than the Nex-7.
That is wrong. If both sensors were at ISO 1600, they would require the same exposure. If the EM-5 is doubling the shutter time, it is at true ISO 800, and not ISO 1600. So, the camera is overstating its ISO.
