For that price, do not hesitate, it's a bargain. Delivered well ahead, well packaged, nothing to say to that side. The construction is robust enough, fits very well on the goal, but a downside, however explains the 3 star: I bought for my Canon 17-85mm is I quickly found that between 17 and 24mm A shadow appears on the edges of the viewfinder of this, it becomes unusable on these focal ranges. So it's a purchase subdued for use on that specific purpose. I know other Canon lenses have a diameter of 67mm, so the game is worth the candle if they open at + 24 mm.
