What about 'beautiful! Excellent dive. Nothing like a 18-55 IS II provides basic with the camera! Well certainly bulkier 'but then nothing to do with the quality of the product and the restored image! This is my first goal of L. series I enjoyed its bulk. This can be an advantage and a disadvantage. Indeed lens dimensions are identical between 17mm and 40mm. The moving part is protected in the block of the goal. Thus there is little risk of play.
