I just purchased this new lens today at my local camera store. When I went to add it to my equipment online here I found that it wasn't listed. In fact, there are only 2 of the 11 RF lenses listed. Here is a link to my lens with the specs: https://shop.usa.canon.com/shop/en/catalog/rf-15-35mm-f2-8l-is-usm. Is this an easy change to make and add it in?
