marginal image quality, but inexpensive
By K. Gittins
Opteka lenses are a low cost alternative to the Canon brand conversion lenses.However, the image quality is not very good, and will only be acceptable on smaller size images.The lens is a big chunk of glass and blocks nearly all of the view through the viewfinder, so you will need to use the LCD for framing purposes.You will need to set your lens at the telephoto maximum, making it a fixed focal length lens (no zooming).It comes with an aluminum adaptor, which normally costs about $15 on its own.It's probably worth $30 if you are not too particular about image quality and are not making fine art shots.
2 of 2 people found the following review helpful.Has vignetting problem at wider views
By Jack Buffington
I read the reviews before purchasing this lens so I was aware of the vignetting issue. In short, for the first about 2/3 of your zoom, your view is as if you are looking through a cardboard tube. You only have a picture in a circular region in the center of the picture. I found this to be acceptable though since I wanted this to bring me a lot closer to my subject. Most of the time when I am using this lens, I have it at the full zoom position where vignetting is not a problem.

OK, but Sub-Par Quality
By cameraGuy2007
If you need that extra zoom, for the price, this lens isn't too bad. But, if like me you care about image quality and clarity, then be warned that I saw a significant downgrade in quality at all focal lengths.Overall, if the price weren't so low, I'd probably have said this was not worth a purchase, but since it's reasonable, it might be worth a purchase.
