Hello,

I have a cannon s2 IS with a built in 10x optical zoom. I'd like to beef this number up substantially. I know there is an add-on lense but its only 1.5 or 2x and they want $100 for it. Could I take the lense out of a projector or photocopier and add it on? Do I need a plano or convex or ? I saw where a guy strapped a spotting scope onto his camera. Not my preferred route but could that work? Would the cameras built in zoom be non-functional if I did that?

I'm wanting to be able to get some amateurish photos of the moon on the horizon. I know I could just go out and get a digital scope but I'm stubborn :-)

This is theoretically possible, but you'd have to do an amazing amount of fiddling to make it work right. The basic idea would be to affix a long-focus lens in front of the camera lens, such that the focal plane of the long lens lies far enough in front of the built-in lens that the built-in lens will focus on that focal plane. Most point-and-shoot cameras won't focus closer than a couple of feet, so the apparatus would be huge.

My old digital camera has no capacity for adding on lenses or filters. I hold an eyepiece from my binoculars against the camera lens and use the display to check my focus. It's a pain to keep everything straight, aimed and in focused, but it does work. Any lenses you can add on will work as long as you can get them aimed and focused. And yes, the zoom works with it.
