Fuji-Fun lens

In the 80s, before this country got money from the North sea oil.  And it was long before the  digital revolution, in fact even before the Walkman not mention any digital sound, the Disposable / One-time use camera was very popular.   Simply the people haven’t got the money to buy proper camera.  Anyway, even with an expensive camera, the use of the camera / film was as such, in one film, it started with Xmas and finished with next Xmas kind.  So that, to buy Disposable camera on each occasion was not such bad idea. 

And local chemist taking care of all those photographic business = sending the film to a lab and giving back the printed pictures to the customer.   Shop people take a film out of those disposable camera and send only the film to the lab = its mean, the left over carcase of those disposable camera filling their bin.   So, I got those discarded camera from their bin, while thinking “One day, I’ll use those plastic lens in somewhere else.” 

The lens to film (sensor) has to be 30 mm, Nikon Z’s frangeback is 16 mm, leaving 14 mm to maneuver.  In order to manage this  14 mm, I used a helicoid extension ring 12~17 mm and M42 to NEX adaptor both from China.  With this helicoid, the lens can give a focus from infinity to 0.3 m close-up.  (Since the lens itself has NEX mount, it can be used on Sony A7R as well.)

The most of lens of those disposable camera is just one plastic disc.   Optically they are very well designed aspherical lens and together with its built-in small iris, the camera can give a omnifocus effect.  (In any distance, the picture would be reasonably good on 3×5 print = Basically, this lens can produce pretty good image with its designated small F-aperture.  But to use this lens in such a way has no point for me = If so, why not use the camera as it was intended = as in an original form )

But I’m using this lens without its small iris therefore the out of focus blurred image, together with its halation is masking the decent image.  And instead of having deep depth of field by its small F-aperture, I used a helicoid focus.  On the end, the lens produces rather funny image = they are not sharp but not necessary soft image like an old Zeiss lens or Kodak Vest Pocket Lens.   So, I’m not sure what is the advantage of this lens. —– and I got, yet another 12 more of them !   I’m having rather absurd life.   😀
