While I do primarily LF these days, I also have an N80. If you are going to do a lot of backpacking and hiking, I would suggest something more along the lines of an ultra-wide angle lens or zoom. I have a Sigma 17-35 which I have found to be a great lens (I use it for > 90% of 35mm stuff). The lens is very sharp. You just need to be careful of the large filter size - 82mm.
