The advantages of this lens are:
+ Excellent imaging characteristics, especially considering the low price
+ For a travel zoom very small and light, even compared to the usual Canon travel zoom
+ The focal length range of 18-105mm is almost every situation (except for animals in the wild, this only works over short distances as in the appended Penguin sample photo)
+ The annoying changing lenses while traveling is unnecessary
+ Good haptics
+ A very high-quality processing: After 2 months of continuous use in the dust, heat, cold and moisture, the lens was like new
In my view, a strong buy recommendation for travel!
