A:AnswerThe lens will physically fit as all nikon mounts are the same. It should work as the lens has auto focus motors in it. HSM is hyper sonic motors. The 3300 I believe does not have an auto focus motor inside the body, but because the lens has HSM, it should auto focus.
A:AnswerYes. The Nikon D 90 has an F mount, and will nicely accommodate this spectacular lens. It will be able to take make full use of the auto focus features between the camera wnd this lens
