How important is an autofocus motor?

    Hello, I am looking at a d3100 for a while now and the only thing that's holding me back is the absence of the autofocus motor. Notwithstanding the future drawback of interchangeable lenses ( I plan on keeping this camera for quite a while) what are the practical, day to day drawbacks? I would consider the 500d as an alternative, but after playing with both I had a slight preference for the nikon.

    Also, the higher priced camera's with af are out if my price range and I am looking to buy new.

    Many thanks.

    Jim

    Not really all that important. This has been answered a few times, most recently by me here ..

    Actually in almost all cases the AFS lenses will focus faster and more accurately than their AFD counterparts, AFS has some other advantages as well, most AFS lenses allow you to disengage the AF for example by just moving the focus ring, the AFD lenses have a little switch. AFS lenses focus more quietly than AFD lenses.
    The one blip was the 50mm AFS from a couple of years back which people were surprised to find was fractionally slower than the AFD version, but not significantly so.
    There are tradeoffs in terms of buying older gear, but AFS has been around long enough now that there's a fair amount available second hand, and Nikon is apparently commited to it going forward.

    High cost of the lenses is the main drawback.

    I posted a list up here a while back of all the lenses that will autofocus on your D3000:
