|I have owned this lens for only 3 days yet… and this is my second DSLR lens to the Canon 28-105mm USM one.
Regardless, I can already see the difference in image quality when I compare the two. This lens is far better in sharpness and color rendition at an equivalent focal length. It is amazingly sharp around 2.8f.
I wish I had bought this one in the first place… and then I wont have bought the 28-105 one so soon.
To sum up:
In the end, I would actually cross off all the cons from the list considering the price you pay for it: a sub-100 bucks lens that gives excellent image quality. People who complain about the build quality probably care more about a solid body than about the end result: image quality.. and will be happy to pay 10 times for a lens that isnt as sharp… so let them pay the extra bucks if they can. I speak from personal experience since I paid about 4 times as much for a USM lens and this one still beats the expensive one by a long margin!!
Recommendation: I highly recommend this lens as a starter lens. I would in fact advise you to get this one instead of the crappy kit lenses that no one would buy otherwise.
