[QUOTE="Steve B, post: 317163, member: 15754"] It's a matter of letting in the same amount of light per a given sensor area. A lens set at 1.8 should let in the same amount of light per square mm on the face of the sensor no matter what. An FX lens is of course going to let in more total light since it throws a larger image circle but that is meaningless when it comes to exposure. For your D3200 the results, and exposure will be exactly the same. If you plan to go full frame in the future buy the FX lens. Otherwise the DX lens is going to work fine and it will save you some money. [/QUOTE]
