It allows me to take a little more wide shots when I lack perspective, but much less than expected because the optical leaves quickly appear dark corners, without actually doing fisheye distortions. It feels like photographing through a tube!
My 18-55 could become a kind of 13-40, but rather a 16-40 to stay fit.
That said, I did not want to opt for a true wide angle, even fixed ... Not the same price for occasional use and still a perspective of more to put in the bag.
An easy way.
