I dusted off a canonet Ql with the 40 1.7, good conditions, got it from nearby town some years ago with a nice tripod and this sun telenet mini 35 add-on lens.
An identical one can be seen here (not mine but identical http://www.worthpoint.com/worthopedia/48mm-sun-telenet-mini-35-lens-tele-305250887)
Now before using it I'm asking if this lens (a doublet, the bigger convex lens is coupled by glue to a smaller negative lens, very simple construction) is a sort of double face contraption that will work as a tele attachment and as a wide angle attachment (wild guess).
This because its separate finder has two frames, one labeled tele, covering about the field of an 80 mm, and a wide labeled frame, which seems to cover a 35 mm lens angle.
Puzzled.
I need obviously to try it but I would be interested in some opinions on this contraption, as well as on the canonet (I remember shooting a single roll with it, results looked like ordinary stuff but lab was not a professional one and prints were small).

btw, the wide frame of the separate finder cover exactly the same field as the canonet's finder.

Usually these came as a set of two add-on accessory lenses, with one external viewfinder that had both wide and tele framelines. I believe you have one of the two add-on lenses,

Which indicates that this add-on lens was part of a generic set (wide, tele, & VF) that was designed to be used with a 50mm lens. You'll likely find the Tele framelines equally inaccurate.
The lens attachment's simple design is typical of that ilk. It is a simple Galilean telescope. Magnification is typically modest (~1.5x, making the 40mm something around 60mm) and guality, especially near the edges of the frame, rather mediocre.

Ty both of you, this clarifies the issue.

The Canonet QL with the 40 1.7 lens is a great camera, I used one many years ago with great results. I would use that camera as it is without messing with the tele adapter unless you just want to experiment and have some fun. Enjoy your camera, wish I still had one.

+1. It is truly a great little camera with an excellent lens. Just forget the tele attachment.
