have been looking at nikon d90 to buy , iam a beginner and would welcome any advice on lenses for nature and wildlife photography. was told tamron 70-300mm with a 2x convertor would be a good start. any tips please?

The lens is reviewed here and gets mixed reviews-

-what I don't particularly like about reviews here is that they don't include sample pics so you can see what people are talking about.
