The 450mm Nikon Q F9 arrived today. Not sure I have seen a more 
beautiful lens in my life. It is in minty mint shape. The previous owner
 really took care of this thing, even the shpping box was very elaborate
 with multi levels of foam, bubbled plastic and protection. The shutter 
on the lens works great, and the lens comes complete with 2 elaborate 
lens hoods (one metal that you screw on). This lens looks to be a great 
purchase, and it came in at less than 1/2 the cost of the M version. What an absolute beauty! Am very happy I bought it. Now I just hope it has the same coverage as the M.
