I borrowed the Canon EF 70-200 2.8 IS lens to see how useful it would be for a portrait session. It was my first time borrowing this lens, so I soon realized what a bad idea it was. It takes beautiful pictures, but it’s super heavy! It’s also a challenge in Insadong because the focal length is too long. You could definitely make it work, but it’s definitely easier to stick with your standard portrait lens.
