I used clear packing tape to affix the barrel of my free, salvaged photocopier lens to an inexpensive haze filter ring so it could be screwed into the Canon close-up lens adapter or the Canon close-up lens itself.

I don't know what power magnification this lens renders. This was a two-part lens system with one moveable lens that fit inside the barrel of the other. I didn't spend much time checking out the potential of the moveable component. I removed it and used only the fixed portion because it seemed to yield the kind of magnification I was after.

I got the idea from an Internet site that discussed self-built telescopes using lenses from defunct photocopiers. The two main shortcomings of using this lens are that it robs or shifts colors (perhaps explained by the fact it was a black and white copier) and that it has a very short depth of field. It does not work if the camera is set in supermacro mode, nor does it work except at an extremely narrow range from the subject that is two or three inches away perhaps. I set my camera in normal mode and crank the optical and digital zoom all the way up, the digital making it easier to see when the view is in focus.

I suppose it's possible the lens does not magnify at all, but merely allows me use the full 22x range of my optical + digital zoom in normal setting (and maximum pixels), whereas the zoom is severely restricted in supermacro mode, which also suffers pixel loss.

Just yesterday I experimented affixing my canon ring flash flash ring onto the end of the deep barrel on this photocopier lens. Although it has no "retainer ring" that allows the flash ring to lock onto the end, the fit was snug enough to keep the flash ring in place while I took these shots. I expect to use it with my ring flash often in the future.

That is absolutely incredible and ingenious!
