One of my concerns investing in an IQ180 was it's dynamic range, My K5's DR is addicting, more than my 5DII and my P45+
So this was a quick test just to make me feel good about the IQ180
2 shots daylight, at base ISO, looking at the RAW histograms in C1 they are very close (IQ180 0-251, K5 0-255) within the error ETTRing correctly
I'll be interested in DxO Marks more precise evaluation
