Just checking how difficult is to focus in the 1:1 macro world. Olympus E-P5 + Konica Hexanon 55mm macro + extension tube. The first three images are 100% crops of 1:1 shots, i.e. the pixel size is comparable:
Sony TV:
Toshiba laptop:
Huawei P8 smartphone:
The laptop screen is the worst of the three, it is unable to produce deep blacks (black 8x8 pixels square):
The TV set instead can independently lighten/darken different sub-pixel areas, and achieves deep blacks when a black screen is displayed (higher DR):
Regards
