This pretty simple chart is a result of very hard work over a whole week. About 500 shots mostly manualy focused at 1/3 f-stop, raw files hacked to register as D5200 pics, read with ACR, best shots exported as tiff to Imatest. Pics analyzed at center and corners for resolution and CA, data collected and saved to Excel. Data to chart conversion done within Excel, prepared for export in Photoshop.
