The AF works quietly, but is for a USM focus not particularly fast (But of course much faster than the version without USM), worse is the fact that the filter thread and therefore all filters very annoying if you use polarizing or graduated filters when focusing turning. But the focus is very fail
The feel is especially for the price absolutely in order, after prolonged use, the result is something Game on front port (the part that extends) But that is not dramatic (eg when 18-55 is this problem more serious) Otherwise Sits all hard and the rings can be easily denoch turn, so on the whole quite usable
A big advantage is the weight, especially when traveling or during long marches, there is great advantage for example to L objective
The problem, however, is the small maximum aperture straight on cameras with APS-C Senor (all Canon except 5D 6D and 1D) need therefore relatively good lighting conditions, an image stabilizer would help here.
One can not at considering the price and the large focal length range About the picture quality complain
There is some distortion at the corners and a slight vignetting, both are but at zoom objective nothing unusual and can create in Lightroom with one click from the world
Or again briefly:
+ Price
+ Weight
+ Picture quality
+ Haptic
+ USM (although might be faster)
-Lichtstärke
-No Image Stabilizer
- External focus
Conclusion:
The lens is far from perfect but because of the price it is well suited for beginners as the most important -The Abbildungsleistung- True, but also for professionals who do not just specialize in eg sports, wedding or event photography is perhaps one objective lightweight alternative to heavy L.
whether we should now take for this or a similar lens, everyone must continue to decide for yourself
