Overall, I am impressed by the lens, the appearance and processing and on the optical properties.
The lens has got very compact and very short with 62 mm lens diameter. Lighting technology, the values at the appropriate level, to modern cameras are not a problem (I use it on my EOS 650D).
Distortion at wide angle, I could not understand in the way, as they can be found here in a few descriptions. But I have made no empirical testing nor have I shot photos comparison with other lenses. I think the normal sense should help a case, not to apply the same standards for such a lens like a much more expensive original lens (partly here the zoom to yes also compared to fixed focal length lenses).
Some points:
The lens is sufficient for most cases and makes the constant changing lenses virtually obsolete.
A lens and a camera body mean less ballast than the normal camera bag for example, the combination of wide-angle (18-55mm) and telephoto (70-300mm).
Who is often travels appreciate the lens, he is prepared well for all situations.
The autofocus works well and quickly.
Super is the minimum focusing distance of 45cm throughout the entire zoom range. That can not have many lenses!
Sharpness in my opinion for ordinary petrol in all area more than adequate. Professionals are the lens eh not want to use.
Total: Can highly recommend the lens.
