Basic choices: value. Canon offers here a very good goal not too expensive. Purchase a complement 28-135 for all types of photos notament trips. I have long considered the comments on this objective on magazines and internet. 2 weeks after purchase I have not been disappointed on the contrary. The effectiveness of stabilization is real and excellent sharpness. Very good compromise between price and efficaité. The sercice Amazon, from order to delivery is perfect (product packaging, responsiveness, delivery within 3 days, the lowest prices with FREE delivery) I discovered an exellent store.
