I have always really liked pictures on this site that were taken with fisheye lenses. But seeing as I'm quite poor, I don't see myself buying a high dollar lens. But after digging around on Amazon and eBay, I have found these fisheyes that attach to the front of the lens you already own. This one is at a local camera shop about 20 minutes from me. And this one is on Amazon. I dont understand the difference between the 0.25 and the 0.20. Which one gives a more circular perspective? Or would these be a waste time and money?

After posting this I also saw this one and it's 0.45, but claims to have 180 degree capability.

The smaller the number the wider the view. The .20 is a wider view than the .25 . You also need to find out how they attach to the lens on your camera, and if you will be needing an adapter. They actually do work pretty good. I used one on my old Sony Handicam back when I was shooting a lot of video, and it helped me a lot to get wide shots of interiors and sunsets that I would not have been able to get otherwise.
There may be quite a bit of "stretch" toward the corners of the images with some of them, as well as some chromatic irregularities (color fringing) toward the edges of the images. Even with all that, they are a lot of fun, and will stretch your shooting envelope.

So the .20 will give a more distorted view? That's what I want.

That's the one then. Make sure that you can attach it to your camera before you order it. You may want to go to that local store, and ask if they will let you check that out before you buy.
It also adds a lot of size and weight to your existing built in lens, so it's necessary to take extra care when you are using it, so that you don't do mechanical damage to your camera by accidentally knocking it into something.
You will probably be surprised by how close you can get to things with it, and how it changes DOF as well as perspective.

Whats irritating, is that Baker Photo Video sells theirs for $89.99 on ebay, but when you are in the store they say its $120. The .20 from Amazon comes with all the different adapter ring sizes and its $50. Hell, I've bought so many step up and step down rings over the last 2 weeks I know I can get it to work regardless. Thanks for the help Melon!

I have one very similar to the Amazon one you referred to, though it is a .25x. It came with all sizes of adapter rings sizes so that was great. I ended up having to buy a used lens to put it on because it didn't give me the full fisheye look I was going after with my existing lenses. If you're hoping for a nice clear fisheye view, you may be disappointed with this approach. As Waddy says, you can expect a lot of distortion at the edges. This isn't the best example since I have an overlay on it, but I used my fisheye attachment on this

Personally, I like the distortion and color fringing :-) So while one of these can't compare to a nice fisheye lens, it is still a lot of fun!
