I'm a total beginner when it comes to photography. I have a Nikon D3300, and want to branch out to a zoom lens. I did a little research and found a lens I wanted, the 70-300mm f/4-5.6G. I found one on eBay that was selling for £50. I was just about to bid when I read that the autofocus of this isn't compatible with my camera.
Can anybody help me out as to which Nikon zoom lens, 70-300mm, to look for that can autofocus with my camera? I don't actually have any idea what the f/4-5.6G means. I know the 70-300mm is the zoom length.
As you can see I'm a complete beginner, any help would be appreciated so that I don't have to keep looking at different posts on eBay to see if the lens I find is compatible and often not finding it.
