Input:
I misunderstood the AF requirements, and assumed that AF would be supported with my D3200. It is not. For the price, this is an excellent lens even if you have to focus manually. My vision is not good enough to rely on that all the time, so I returned the lens in favor of a newer model with compatible AF. With a fully compatible camera, I definitely would have kept this lens.
