I was recently asked what I thought of the D500 / Nikon 200-500 combo... I think the D500 is outstanding for birding, focus is fast and accurate and the burst rate is amazing. Regarding the lens, I believe that the best way to answer is with the following shots using that combination.
Nikon 24-120 f4 VR...Nano Coated, US Version, Like New ! $675 Canton, MI (48187) This lens is pristine.... Includes original box, paper work and Nikon front and rear caps and hood. Very clean and super sharp images. $675.00 plus 10.50 USPS Priority Mail ( US Only ) PayPal gift...
I have a new in the box Promaster Tube set... I received as a gift right after I purchased a macro lens. They are well rated and are full function auto on Nikon cameras. They retail for $100.00 on Amazon
I will sell for $75.00 plus 7.00 for priority shipping...
Congratulations on being selected. It really is a beautiful capture and worth every accolade it can get. If I were a publisher, I would put that in my book as well.
