Updated Samsung Tests - Auto-Correction effects on MTF - Klaus - 11-29-2011 Hi Folks, the Samsung NX tests rely on Capture1 RAW conversion. In C1 it is easily possible to enable/disable distortion auto-correction so the effect is both measurable as well as directly comparable here. We had a debate on this a couple of times. I've now included both MTF/Quality charts in the 20/2.8 and 30/2 review (mouse over). It is fairly obvious now that the correction comes at a price - the higher the correction level the higher the loss in quality. So the NX 20/2.8 looses more here than the 30/2. I reckon, however, that the C1 algorithm is a little rough. I haven't seen such an extreme difference in the M43 section. NOTE1: It may be that you have to flush your browser cache. NOTE2: The uncorrected RAWs produced a higher peak so I had to adjust the max. value accordingly. NOTE3: In future tests I will only provide the RAW chart. It is too much effort to generate both.

[/quote] Fixed. Regarding comparison ... it's more a 1/3-1/2 mark on the 30/2, yes. DISABLED DC: ENABLED DC:
