As always, delivery service, fast and efficient. Reasonable prices compared After the Tamron 18-270mm, I was looking even more versatility. 16mm is a real plus, 300mm, the difference is less sensitive. Well finished goal, good handling, robust, the focus and zoom rings to put were reversed compared to the 18-270mm, a habit. Mount lens adapter ring Sony LA-EA4 + NEX5 device. True to my expectations, happy with my purchase.
