The most inexpensive wide-angle zoom for a full frame. Made quite high quality, there are no serious distortions inherent in cheap lenses. Light filters should be chosen special, thin. And then there will be strong vignetting from them at a wide angle. The kit comes with a lens hood, which is of no particular use, except that the lens looks cooler with it, but do not go into any bags and backpacks)) Also included is a very cool case, I carry every little thing in it when traveling :)
