The lens multiplier is 2.7, so a 10mm lens will be equivalent to a 27mm lens on a regular 35mm camera. That's "wide" but certainly not "ultra-wide" (its about 67° horizontal field of view). That would be just fine for me, but many might want wider.
On the video interpolation, I'm not an expert - I'd be grateful if someone knowledgeable could pass judgement on its video performance relative to its competitors.
