I didn't read their "take the chance" advertising line as "take the risk" but rather "take the opportunity". Big difference ;-)
The performance is undoubtedly good - but I'm still waiting for a clear and unambiguous explanation as to what the "no zoom lens" issue is all about. If this performance comes at the expense of being restricted to one or two specific lenses then I'd say this is a bust for any true video/stills photographer, i.e. anyone who is seeking a versatile, high-performance camera platform that can tackle any job rather than a hobby flyer with deep pockets but no particular photographic ambitions.
