Comments seem to indicate the second lens is little more than a large bright viewfinder, as there is no linkage between the viewing lens and taking lens, making it useless for focusing. Perfectly in line with the Holga philosophy.
Right now in Spain they're holding the Running of the Bulls,
followed by the Soiling of the Pants,
and the Burying of the Idiots.
Yeah, it wouldn't make sense for Holga to make something that complicated...especially since even the Blackbird Fly doesn't have a proper focusing lens, and it's a much more intricate beast than a regular Holga.
I actually considered ordering one until I got to demo it yesterday. The viewfinder is like that of the Blackbird Fly, it's round not square. WTF? Okay, it's not a ground glass but what good is a round image when the exposed film is square. Makes no sense to me and the freestyle fella tried to explain how it would be to $$$$ to make it square. hmmmmm.
