I have all Nikon Lenses. I chose all the lenses of the same manufacturer because there are less color variations between the glass by the same manufacturer than by different manufacturers. I currently have AF18-70mmf/3.5-4.5 zoom, AF80-200mmf/2.8 zoom, 28mmf/2 manual focus (used only for Aurora Borealis photography), AF50mmf/1.8, AF300mmf/4. My next lens purchase will be a 500mm/f4. I also use a 1.4x teleconverter. I am going to purchase a 1.7x teleconverter. The 18-70 is for wide angle and normal usage, the 80-200 is my most used lens. The 300 is my 2nd most used lens. The 28 is taped to infinity focus and set at f/2 for photographing the Northern Lights. The 50mm is my least used lens.
