It has two lenses, 4.25mm and 6mm.
The wide angle has apparently an equivalent focal length of 26mm (in full-frame terms). Then when you want to use the other lens, the screen offers a "2x" icon to press. Most, if not all, reviewers put that lens equivalent at, naturally, 26mm x 2 = 52mm.
And yet, 6mm divided by 4.25mm equals 1.4x factor, which would put the other lens in the 37mm category, not 52mm.
What gives!?
