After scaling down my Nikon kit, I realized that I only have fast zooms and one prime left. The Nikon Df is my all time favorite camera to use for everyday carry or general shooting use. I wanted to get some smaller in size lenses that I could keep with me but also not spend a lot of money on them.
Went to the local camera store and they had a few options. For under $200, I was able to get the Nikon 35-135/3.5-4.55.6(for general one lens use) and a 70-210/4-5.6(for use with my 28-85/3.5-4.5 when I want a 2 lens option).
Very happy with them, even though they are the push-pull variety of lenses. I find the IQ just what I like and the sizes fit nicely into my Lowepro transit 250 sling bag.
Here are some examples:
