Welcome to Nikonians! The D70 has an AF motor built into the camera body which provides AF with All AF Nikon F mount lenses with the exception of two. The D3200 does not have an AF motor built into the camera body and therefore requires lenses with AF motors built in such as the Nikkor AF-S type lenses.

As other have said here the 3200 does not have an internal focus motor so you must use S type lens that have motor built into the lens itself.
If your just starting out the "Kit" type lens are a good start 18-55mm. For longer reach the 55-200mm works well. For a medium wide-angle the 35mm f/1.8 is excellent. All relatively inexpensive as lens go. $250-$400 range. (The 18-55 usually is provided with the camera the reason for designation as "kit" lens. In some cases the 55-200mm is also provided in the kit, depending on packaging by dealer)
If you have some serious doug to spend, and want an excellent serious wide-angle lens get the Nikon 10-24mm f/2.8 the pictures you can take with it can knock your socks off.
If you want a serious replacement for the 18-55 , get the 17-50 mm Sigma F/2.8 lens, it too, if you know what your doing taking pictures, will knock your socks off as well.
These last two lens are prices are bumping up around $1k, some time if they they are on sale, show up less than $1k.
