Summary: Not sure in what cases this lens is actually usable.... Unless you're going for that "soft glare" feel, it's just not usable. I decided to keep it just because it was so cheap, and maybe I'll find a use for it, haven't yet.
but then again it is great if you can afford to have lenses sitting around

Summary: I bought this back in college because I was eager to add lenses to my equipment. Let's just say that I used it a few times and it's been sitting in my bag ever since. That was back in 2010. I thought about selling it, but then again it is great if you can afford to have lenses sitting around.
Not a bad deal as long as you have the right lens ...

Summary: This one I found a little difficult to use with anything larger than an 18 x 55mm lens. I've got a stock 50 mm that I never tried with it, as I decided not to keep that lens in favor of the 18 x 55. On that lens the action of this macro is much more intensified and believable at the 18 - 24mm range.
Summary: This is an attachment to an existing lens and works ok. It gives a wider angle, but not the fisheye effect. If you are looking for the true fish eye effect that makes that bubble, this barely does it.
Summary: Here's the skinny on this Super Wide Angle Panoramic Macro/Fisheye lens. I bought this as a toy lens for my Canon nifty 50mm f1.8. For the price I didn't have much expectations and once I got my hands on it there's some pros and cons.
