I am soon going to buy my first DSLR and have been looking at the Nikon D5000. I was wondering which lens would be most suitable? My photographic interests are in landscapes, flora & fauna, and I will also take shots of family, people and when I travel. The lens I think would suit my needs is a superzoom, say 18 to 270.
Does anyone have any experience, either good or bad, using a Tamron or Sigma superzoom lens on a Nikon body? I have heard that auto focus can be slower than a Nikkor lens. Any other problems that I might encounter?
Any feed back would be appreciated. Either on my choice of camera or lens or combination of these. I don't have a huge budget, unfortunately.
