Need adaptor recommendation

I have an issue which is that I want to purchase an adaptor for my canon S400. I went to the scopetronix site and looked at their maxview pro 40 adaptor for about $129.00 but then realized that I also needed a step ring which runs for about 80 bucks giving me a grand total >$200! As you may already realize, i'm on a limited budget, so I was wondering if there's any way I can get around this? Any help will be greatly appreciated. Thanks

Mauricio.

Mauricio,

The problem is that your Canon S400 has an external zoom lens with no filter threads, so you can not use a simple step ring to attach the camera to the Maxview 40, or any other eyepiece. The reason the Scopetronix attachment kit is so expensive is that it must attach to the outside of the lens and still allow it to extend and retract.

Unfortunately, the only other solution is to use one of the attachments that clamp to the outside of any eyepiece and hold the camera just in front of the eyepiece. Scopetronix sells those too, but it is not a very good arrangement because there is no physical connection of the camera lens and the eyepiece, so alignment, stray light and vignetting will surely be a problem.
