The specs listed in the description are all over the place. I wouldn't be surprised if most of the info given is incorrect.FYI I actually saw that last week while browsing...
The pic shows it to be a S2 Z4 but the specs are copied from a S3 and the max. illumination distance shown is 60 m, which is 1/2 that of a Z4?
60m illumination is the spec for the standard 2.8-12mm bullet
The one I received definitely is a Z4E with a zoom of 8mm - 32mm. It's printed on the box and camera and with it zoomed all the way out, the FOV is roughly half of what my 3.6mm lens T54IR is.
