Light weight, cheap & super sharp! Nikon made some great lens back in the day. These are plastic & not built great but hey they are very light and already lasted this long so whats another 20 years more. I got the one on the left, Nikon 28-80mm f/3.3-5.6 G, for only $27! I've owned the Nikon 50mm f/1.8 D since 2004 and I got that new for 98 bucks; Its even cheaper now, maybe $50. I recently picked up a used Nikon 35-70mm f/3.5-4.8 for $76. All these are fantastic plastic.
