Fun from a broken Camera (2)

G9 (2)-1-A09A6026-001

It was two weeks ago when I showed this photo of Canon G9.

Among the disassembled component, I found some of them are useable.


Such as the front lens alone (photo above left)  could be used as a 50 mm F2.6 lens

and the second group of the optics (photo above center) is a very strong diverging

(concave) lens = could be used to widen the view of a pinhole camera.


In order to use a lens, it has to be mounted somewhere — to a lens mount or

to a filter ring etc. —– unless it got exact diameter or screw pitch, we need to fill

the gap and glue (epoxy) them.  

I cut a beer can’s thin metal to the needed diameter and fix it with epoxy.


To do this kind of work, I bought M39 to M42 adapter ring and M42 to Nikon F

mount adapter. (Those item’s cost were only few pounds though, it took 2 weeks to 

get them here, and as being as cheap Chinese products, noting is what we expected

= M42 screw was slightly larger and couldn’t fit to the Pentax original mount.  

And the clow of Nikon Mount bayonet was too thin hence it was too loose.  

For M39 to M42 ring, I “re-cut” the M42 screw (Photo left in the center).

Nikon to Canon-1-A09A6530 (Photo Left : Nikon to Canon Adapter though,

part of its diameter was 0.5mm too large

= needed to file-down !)

(Such laborious cutting work with file is 

nothing but a good Zen practice.  😀 )

Second group of concave lens aforesaid was

mounted on the center of M42 to Nikon 

mount adapter. (photo above center)  

And the Front lens of G9 was mounted

on to a Nikon mount adapter via M39-M42 ring. (photo right


So, what was those hastle for ? —– The photo (right) here was taken by the

front lens of discarded Canon G9 Camera aforesaid.

(Left photo was also taken by a single lens came from another broken zoom lens).

( I’m preparing those lenses for the coming flower season ! )

If you like to see “sharp but ubiquitous” photo, please go to phone-camera.

The photos here, the images were full of aberration and halation still where

the focus lies, it’s sharp.  (Look the enlarged photo) —– they might be

the images what we are actually seeing.

(like impressionist painter had found).  🙂

    […] I show you a yet another homemade lens : G9 Lens (with Nikon mount).   As a matter of fact, this lens appeared here before in the other guise. […]
