The lens is nice and light. It makes beautiful photos, which I have found no blurring. However, I did not examine the pictures with a magnifying glass to find a blur. The photos are gorgeous of the colors and exposure. In the dawn light, the autofocus works a little imprecise, but this makes the autofocus of my CANON AF 28-80mm lens-not better. If the autofocus does not correct adjustment at extremely low light, I turn it off and simply place the picture focus manually.
The lens changes its zoom does not inadvertently (lengthens when gravity pulls) when the camera dangling around the neck. For extreme cases, the lens even has a lock. The zoom operates smoothly, it is not jerky adjustment when turning the zoom ring to feel.
Yes, it is produced mainly from plastic, but that does not see you at the lens. (A Mercedes can not you see the plastic Stroßstangen on). Lightness is welcome to its price and if this does not suffer the photo quality, I do not care whether the lens of plastic or manufactured Krupp Stahl. At least we should not be ashamed if you zoom extends the presence of people ...
I use the lens with a Canon EOS 1100D, am excited about the great photos that allow me the combination and can only recommend this combination any casual photographer.
