For some time I am looking for an adaptor to enlarge the wide angular range of my Canoan A70. The camera has a bayonet under the removable decorating ring of the objective for mounting an adaptor. After I was informed from Brooks Leffler, Philo and Scott Haefner about so-called "Bubble Panos", it should be a fisheye lens.

Shot A70 |
| Brooks, Philo and Scott they all
use a fisheye lens from Nikon. With that it will be possible to show
an angle of view of more than 180 degrees.
Unfortunately, after long look for find, I could not find something comparable for the Canon A70 and so I have tried it with the Fisheye FC E8 from Nikon. |

The Nikon Fisheye Lens FC-E8 must be mounted with an adaptor at the Canon A70 |

| Of course there is no possibility to mount a Nikon objective at a Canon camera. So I must build my own adapter. It consists of an aluminum hull and is put on on the bayonet at the Canon camera first. A thread in front of the adapter (28 mm x 0.75 mm) then takes the fisheye lens. The back lens of the fisheye must be placed as near as possible to the front lens of the camera objective. If the camera is swiched on, the objective moves a small pice over the normal position. This must be taken into account at the hull, so that the objective doesn´t bump at the inside front of the hull when the objective moves out. The camera could suffer a mechanical damage at this and stop its service with an error message. |

| First test shoots
showed that the combination "Nikon fisheye and Canon camera"
provides good results. The focal length of the cameras 35 mm lens is
extended by the factor 0.21, so a focal length of 7.35 mm arises in
the combination now. The angle of view is approx.180 degrees and one
must pay attention that one doesn't always have his fingers or feet in
the picture.
For KAP the camera frame must the be adapted because the centre of gravity of the camera is shifted by the weight of the fisheye lens. Through this the camera isn't in the balance any more and the servo permanently must "pull" at the frame to hold it into position. |

I like to be available for questions, suggestions or experience exchange.
I would be very pleased about an entry in my visitor's book.
