I have a D80 and am looking to get a good lens to take down to the beach with me this year. I currently have the Nikon 18-125 "kit" lens but was thinking of going with a fixed lens this year or possible a combination of a few lenses. I primarily take pictures of the kids and am rarely zooming in that much so I was thinking of maybe doing an 50 mm or 85mm as the primary lens and then maybe going with a 105 if I didn't want to get too close. Any thoughts? Thanks!
