Are these lenses any good? (for 35mm camera)

Question

I'm looking for a wide-angle lens and a fish-eye lens of some sort for a Canon Rebel G. I'm not sure if they make real lenses for this thing or if this is just how they are for older cameras.

Are any of these decent?

Are there any better options out there for this camera?

Answer 1

These are called the poor mans wide angle or telephoto. They are filters that s***w in front of your lens. They are worthless. Why do you have to point a gun? Point a banana...

Answer 2

Yeah those s***w-on lenses are pretty crappy. If you want a real fisheye you'll need something like this: http://www.amazon.com/Canon-15mm-Fisheye...
