The objective is equipped with a button for manual focus, but it will need very little given the speed and quality of autofocus equipped with the SWM-AFS technology. It is adaptable on both full frame as the still vacant by little internal drive sensor devices (type D3100 / D5100). The objective as all this nikkor range, comes with lens hood and fabric pouch, enough to carry them in short trips.
Also with a Nikon - Lens - AF-S DX 35mm f / 1.8 g, I was afraid of having two very similar goals, but in fact there are quite complementary. The opening 35mm wider, even with APS-C sensor, is less suitable for portrait photos that 50mm which squeezes more.
Finally, the objective seems robust in itself, but the painting is quite fragile and some small contacts made some splinters. Surely repaired with a suitable kit.
