Hello, I've recently picked up a D40 for myself, and I'm questioning whether or not to pick up another lens. The kit lens it comes with has a minimum aperture setting of 3.5 but thats only when on 18mm. I'm usually shooting at 35-55mm and the aperture setting is 5.6 which is really quite high. I'm wondering if there is a low cost D40 compatible AF-S lens with a lower f/stop number. Also, is there anyone who will recommended a cheap telephoto/zoom lens for the D40 as well. Thanks.
