Hi Michael, The D3200 can use any modern-era Nikon lens with the AF-S designation with full availability of all autofocus, auto aperture, auto exposure, and image stabilization features. Older AF lenses won't autofocus but can still be used for automatic exposure. You can use Nikon AI, AI-S, or AI-P manual focus lenses. Nearly all new Nikon lenses are AF-S with the focus motor in the lens. The Nikon flash units that can make optimum use of the light control features provided by the D3200 are the built-in flash, the Nikon SB-900/910, the SB-700, the SB-400, and the SB-R200. Various older units will not be able to access all of the control functions provided by the D3200. The NIKON D3200 by David Busch is a excellent reference if you own or purchase a D3200. Hope that this helped.
