Summary: Fish Eye Lens??

Comment: I'd LOVE to be able to write a review on the pictures this lens allows me to take...but the lens didn't come with a step up/down ring for my 58mm Canon Rebel XLI camera and NO photo shops I've gone to have the size I need to fit this adaptor lens to my camera.
VERY frustrating.

Summary: Works...

Comment: Yep, you know what they say: "You get what you pay for".
All in all I am quite satisfied with this purchase. Obviously you won't get the quality pics you would with a dedicated lens, but for the price, you can't go wrong. I use it with my Canon Rebel XTi and the results are pretty good. I use it most for landscape shots.

Received the lens, adapter ring, and lens cleaning kit: what a bargain!

Summary: Fun Fun Fun

Comment: This product arrived exactly as it was supposed to along with a free lens cleaning kit. It screws on to the kit lens that came with my Canon Rebel XT. Images have been sharp and clear and never dissapointing. I couldn't have asked for more in this fun little lens! Highly recommended to everyone!!!

Summary: Not bad but expected a little more

Comment: I purchased this lens about 1 month ago and I'm generally pleased with it. I have a Canon Rebel XTi with a kit IS 18mm-55mm standard lens. In a nutshell, here's what I think.

The pros:
- low price
- lightweight
- sharp image
- includes lens bag
- creates interesting effects
- creates great macro shots

The cons:
- Compatibility with Canon 18mm-55mm IS lens. Requires 2 "step down" rings to mate the lenses together. As a result, this produces a porthole effect (which might be what you're looking for)
- step down or up rings are NOT included with this lens
- lens caps do not fit snug and always fall off. They're pretty useless.
- edge detail falls off considerably (blurry) with blue edges forming on high contrasting objects.

The verdict:
To achieve the desired effect (fisheye warped / wide angle shots with sharp detail on the extreme edges), this lens does not do that so I'll be looking around for a true Canon / other band fisheye lens.

Summary: Hmmm.

Comment: It's a little flimsy, and doesn't really fit on the rebel all that well. With a larger lens it doesn't really have much fish eye at all. Since it's not the right size for my lens and has to go on an adapter ring, there's a little vignetting around the edges.

A friend of mine has a video camera that it fits on without the adapter ring and it looks cool for that.

Overall, it does work... sort of... but I wish I had spent a little extra cash and bought something a little better.
