I looked for the Sigma mainly because of the aperture being wider than the Nikon 18 - 105mm and a review in DxoMark telling that it could be a better choice as a better lens. But there certainly is the drawback of the extra 55mm on the Nikon lens. So that's why I'm trying to figure out if it is worth it.
For the longer reach I was thinking about the Nikkor 70 -300 mm f/3.5 - 5.6 VR in a near future. Any thoughts on this? Should I consider taking the kit 18 - 105 mm and the 70 - 300mm and let the prime for the future?
Anyone who has any additional comments please feel free to shared it. I still have a couple of months to make the purchase and try to figure out what should be my start up pack
