Possible lens extension

I was wondering if there was any way to put an extra lens on my Canon FS200 like a fisheye or something. Even if it requires either modding or DIY type of stuff.

I was wondering because I want to add on a DOF adapter for my video camera.

There is the link for the actual adapter. Could I possibly fit something like this on my tiny FS200?
 
There are lenses/filters which are specially designed go on the front of cameras which already have lens elements. They work great, however each one you add does reduce the overall image quality. Putting one or two for video is okay, but stacking more than 2 will give obvious image distortions.

Easiest way to add such a lens to a camera that doesn't have a screw-mount already is to purchase a step-up ring and then super glue (voids warranty) it to the camera. Then add the filters on that thread interchangeably.

Once you know your thread size you can order what you want off ebay or similar site (I order off of ebay cause its cheap and quality is pretty good).

Is there a particular effect/lens you were looking for?
 
I built that adaptor. I think it works pretty well. The main issue I've had with it is that the minimum focal distance on my camera is FREAKING HUGE... so the adaptor has to be quite far away from the camera... 2.5 feet-ish. An acromat lens in between would allow it to be closer by doing funky physics stuff with the light coming in.

Any camera pointed at this thing will instantly gain "real 35mm Depth of Field"... you'll need to add light to your scenes as it eats alot of light, and the resolution won't increase... but the DOF problem of small chip cameras will be solved for you. I ended up having to build a rail system for mine to hold it all in place, so the utility of a small camera is completely diminished as you're going to be tripod mounting a 3foot long piece of equipment.
 
It doesn't appear that your camera has a threads for attaching filters/lens adapters. Most cameras have threads around the edge of the lens so you can screw in a wide angle adapter, but just checking the specs from Canon, I don't think the FS200 has threads. So mounting your camera to a DOF adapter might require a fix of some kind...
 
it'll be fine. and the threads won't matter with this particular adaptor. You'll need to check the specs on the camera for the minimum focal distance, but it'll probably need to be a ways back unless you buy an achromat for it... but again, you don't have threads, and that's ok.

Here's mine:

Focal Distance Minimum 2.60 mm
Focal Distance Maximum 96.20 mm
35mm Focal Distance Minimum 45.80 mm
35mm Focal Distance Maximum 1695.00 mm

This is what for I got for it's specs. But I'm still learning so I don't really understand how it will correlate. Will it still have to be about 2 feet away?
 
Another questions: So if it's X amount of feet away will I be able to get it alligned so that it actually sees only whats through the adapter.

Also I heard that it will produce an upside picture. Is there any way to reverse that other than post production.
 
The ground glass (spinning cd) will have to be at least the minimum focal distance (MFD) away from the lens of your camera for it to be able to get you a clear image of your picture. You may then have to zoom in slightly to get the image size you're looking for (the 35mm thing ~~ 21mm x 27mm).

My problem is that as I zoom in, my MFD gets longer.
