I love this lens. It’s tack sharp on all the camera bodies (even the 5DsR) and it a great story telling focal length/lens.
It gets used for environmental portraits, BTS, Events and Weddings.
Sharp wide open and bright in low light a sure winner. The Sigma ART is a hair sharper but I don’t like how they render images and they seem too clinical for me.
If you are a portrait, wedding or event shooter and run Canon cameras this should be in your bag.
