I just got this filter and my first tryouts show some vintage (dark) on the corners of the pictures

As a landscape photographer I consider the mount's change as disastrous. A very expensive EF 16-35 f2.8 lens was converted into a 40-57, terrible!!!!!!.
I consider the filter system ingenious but the loss of amplitude in the focal length a fatal error.
I just acquired a Fuji GFX100s and with this I say goodbye to Canon after 30 years faithful to the brand
No, I would not recommend this to a friend.
