From the info you posted here, it may or may not be compatibly with D350. Because Vivitar is one of the 3rd party lens maker for the Canon, Nikon, and other camera.
The best 3rd party lenses for canon are Sigma, Tamron, and Tokina (not in the order). If you buy the used one you need to make sure it fit your D350, which use the EF, or EF-s lens.
