I have a Sigma 150-500mm I bought for for wildlife and I am happy with it, though because it's a heavy lens I usually use it with a monopod or a tripod.
For landscape you might want to consider a wide angle lens to capture the breadth of the scenery. I use a Nikkor 10-24mm for landscapes.
Thanks for your reply, Mac. So, for landscape; i.e., mountains, etc. you get the distance needed with your 10-24mm?
