Pretty Decent Lens, | Rating: ★★★★★
“I’ve had this lens for a couple of weeks and I’m pretty happy with the images I got from it. I bought this lens as a secondary lens. I use it mostly for family pics, or non-job related shootings. Personally, I think that for the price you can’t beat it. It’s a pretty decent lens.” – by Ismael

For the price… | Rating: ★★★★★
“This is a cheap lens, but for the money, it doesn’t get much better. Great walk-around lens. Excellent if you are looking for a lens to use in whatever everyday situation you encounter. It is fast, it is easy, it has great DOF, large aperture, solid build, fast focusing, sharp pictures, and low price. you can’t ask for much more than that, especially if you are paying so little.” – by Joey Daniels

Good starter lens | Rating: ★★★★☆
“Comparing this with the Canon kit lens will reveal insignificant differences. Both decent lenses for basic still photos, but it really shoots as a 45mm-112mm lens because of the XTi’s 1.6x field of view crop factor. Next step is an upgrade to a wider view Sigma 18-200mm lens [[ASIN: B000NOSCGM]]. I’ve seen photos with this lens that are stunning. Canon lenses are excellent, IMO, but they tend to be overpriced for the minimum quality trade-off with third party lenses like Sigma or Tamron. “ – by R. Croft
