Great for the price

  • Summary: I saw some reviews that showed that this lens was sharper than the stock Canon 18-50mm and that is why I got this. Has noticeable chromatic aberration as a trade off though. Feels sturdy, has rubber on the grip where you turn the lens, feels of good build quality. Got some of my best images with this image. Most definitely used this more than the 50mm just because of the zoom convenience.

Used for IR photography

  • Summary: Bought this lens because it was less than $100 and works in the IR spectrum without hotspot. As with any lens in IR, you may need to use live view to focus given the focus shift of the given wavelength. At 18mm, focusing without the live view, it is spot on. At 50mm however, live view is required. It isn't as sharp compared to my other $400 sigma lenses, but for IR work, it imparts a certain feeling to the picture that i rather like. Otherwise, great lens for the price.

Inexpensive Sigma Lens

  • Summary: I purchased this lens because of is low price. I recently purchased a Canon 7D and wanted a wide angle lens but really couldnt afford good glass. This lens gets the wide shots but it's not the sharpest.(nor is it close.) I am happy witht he lens based on my current need for a wide angle and it's super low price. As soon as I get the funds I will be upgrading. Good for now.

Basic zoom lens, for cheap

  • Summary: What can you say? I bought this as a cheap back up lens. This is a basic, no-frills, inexpensive lens. It is well-made, but picture sharpness is hit or miss, it seems. I am an amateur, so I can't tell if there is any distortion at either end of the zoom range, or in the middle. I haven't seen any significant chromatic aberration yet, but I expect there to be some considering how cheap this is. The auto-focus has difficulty in dim light and bright (sun) light.
