Among my Canon L-series range of goals, I already had the previous version the Tamron 18-270 f3.5-6.3 DI II VC LD used with a Canon 50D true travel companion. For a tourist trip to Japan this summer, I purchased this 16-300 interested in developing ultrasonic that had no 18-270. Since I took over 2,000 photos with this objective. That happiness: enlargement of the focal range, focusing much more accurate and fast in all conditions of use, flexibility of the zoom ring (marked improvement over hard point on the zoom ring but sufficient firmness avoiding its opening by its own weight), and more than good optical quality for this type of zoom everything. NB. Besides, my opinion is confirmed by the comparison test against its equivalent at Nikon in Issue 366 September of image hunter).
