The 10x optical zoom sounds great, although I expect the wide angle is
still not very wide?

The lens specs are 6.3mm to 63mm, in 35mm equivalents that is, wide angle
38mm to 380mm at full optical zoom.
So it's a reasonable wide angle.

In 35mm terms hardly a wide angle at 38mm! A 35mm lens was seen as a
moderate wide angle at 54 degrees horizontally, 40mm lenses were seen as
wide 'standard'. 'Proper' wideangle really meant 28mm( 65 degrees) or
less. My ancient, 1970s, 20mm Zeiss Flektogon gives a really impressive
width of view at 84 degrees and more extreme angles were/are common.

Seems a common problem with many (most/all?) digital cameras is that the
*wow* factor of the telephoto end of the zoom is what they go for while the
very useful wideangle end is ignored. Probably cheaper to make them that
way and it appeals to the natural voyeur in us!
