I took some photos of
a book displayed on Sony DPT-S1. Internal storage was used.

1/8
Page 13 in moderate light shot with fast shutter speed. This is approximately what a PDF looks like on the device under normal indoors ambient light.
2/8
A close-up using camera's optical zoom of the area in the red rectangle from pic 1 shot with fast shutter speed. No zooming done on Sony, so this is how accurate the small print appears on the screen. Depending on your eyesight and lighting conditions, I guess it is still borderline readable?
3/8
Page 13 shot with slow shutter speed. Mind the color distortion, it is of course caused by the camera. The rest of the pics are similar.
4/8
A close-up of the area within the red rectangle in pic 3, using camera's optical zoom. No zooming on Sony.
5/8
A close-up of the area within the yellow rectangle in pic 3 using camera's optical zoom, and fully software-zoomed in on Sony. You can see the rendering of the small fonts break apart. The same happened with Foxit Reader 7.3.0.118 on PC, which implies the text simply doesn't scale.
6/8
Page 14 in default view (fully zoomed-out). Regarding font size and layout, this is what most pages in the book look like so it is probably the most practical reference for assessing performance.
7/8
A close-up of the area within the red rectangle in pic 6, shot using camera's optical zoom. No zooming done on Sony.
8/8
Page 11 in default view for indication of the readability of diacritics on medium-size font.
