Yes! Lightroom’s primary purpose is organizing, and editing, raw files. Adobe continually updates their software to work with the latest cameras’ raw files, but once a camera is supported, you will be able to open and edit raw files. (Canon .CR2/.CR3, Nikon NEF, Sony ARW, Sigma DNG, etc. etc.)

Lightroom is all about helping you organize, view, and edit your raw files. Sometimes a brand-new camera has a file type that is not supported, but Adobe updates Lightroom constantly to work with new cameras. 

Lightroom is the most popular choice for opening and organizing your raw files because its catalog system allows a lot of flexibility and unique features that you would not be able to use with more traditional editing techniques.
