I am currently re-evaluating my lens needs. I was going to get the baby VR, but started thinking that perhaps I should get a 50mm, 85 or 105mm, and a 300mm. Since the 50mm is only around $100, that one is in the bag. The 85 or 105 will wait. My question is about the 300mm. I am looking at used lenses. Could someone tell me would all of my metering and what-not work with my D70 if I were to purchase a Nikon 300 F4 Ed (if) Af? Also, what is the quality of this lens? I would be using it for wildlife shots. Thanks.
