So i asked to show me some things onscreen:

<Date Taken [Y-m-d_H-M-S]>
<Width>x<Height>
<ISO Value>
<Exposure Time>

But i see only date and resolution. No ISO and exposure. But i can read by myself this data from exif menu. Why? For my previous photocamera i can see onscreeen all this data.

For ISO value, it's normal, this field is in Makernotes (not supported in info)
But exposure time should be showed...

[vorob]

Well, i don't see anything normal here. For my samung i can see iso value, and for my canon i can't. Both values are in exif info. There is no logic.

Info doesn't support Makernotes

[vorob]

Well, what is it, Makernotes?

With EXIF you have standard info (camera, image, thumbnails, gps), and closed info (makernotes)
