Looking advice on a 150/170-500mm lens for D3100

Hi

I'm interested in purchasing a 150/170-500mm lens for my D3100,i'm pretty new to photography but like the idea of having a 500mm lens as it would be good for my hobby of aviation and photography

Basically i would like to get one second user off eBay that would AF on my D3100..

I was looking at this and was wondering if anyone could tell me if this would fit and AF?.....Sigma 170-500 mm F/5.0-6.3 APO Aspherical Lens (AF) | eBay

SIGMA 170-500mm 1:5-6.3 D APO ZOOM LENS, NIKON FIT + HOOD, CAPS, TRIPOD MOUNT | eBay

Any help would be most appreciated..

Welcome to the forum.

The 170-500 was never a top performer,also it does not have a focus motor built in so would be manual focus on your camera.
