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.
Peter Marshall: When you pat a dog on its head he will usually wag his tail. What will a goose do?
Paul Lynde: Make him bark.
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.
