Anybody have this lens or know anybody who does. With a D100 it should come out to about 105-450mm. I'm kinda worried about distortion with this type of a zoom lens. Also its listing for 300 and I've seen prices as low as 230. Anybody know where I can get it for less? I already have a Nikkor 35-80mm f/4-5.6D AF Zoom and my budget is set that the next lens I buy will probably be the last for at least a year or two. Therefore I'm thinking about the 70-300 lens. Any other alternatives out there?
