An excellent and "affordable" lens compared to RF lenses. I mainly use it in the studio, where it is excellent and shows the true image quality it can deliver. However, this does not make it inferior for landscape photography, portraits, etc. in daylight, where it produces excellent images, especially in the center, with most apertures (the sweet spot is f/8) and focal distances. I highly recommend it and it should not be missing from any photographer (amateur or professional)
