Hi Jmirko!
No, its not the same, while the E920 has very basic options for .epub, .mobi etc. it has a variety of zoom functions for PDF filetypes.
I was very surprised to find out it has nearly the same options as the M92 had, it has point-to-point, crop margins, fit to height or width, it even has glyph emboldening or text darkening! (whatever you call that)
I will take a closer look at the zoom options so I can tell you exactly what kinds there are, there are so many that I can't remember them all out of my head now xD
