Thank you very much for your comments. The comments I and my wallet likes is the first one from Thom Hogan in the comparison of D500 and D850, which means no need for a D500 for me. The type of photos I do, are Street/street portrait of ethnic people, landscape and Kite Surfing, the latter is the reason I got the 200-500mm, but not used that much, as I have to drive car to the location and stay there overnight. Unfortunately I don’t do any wildlife. My conclusion is therefore, that I get more out of D850 as a general purpose camera, as Shun Cheung also mentions, and now that a local shop has reduced the price by 20%, there will be a little left for a couple of XQD cards and then use my wife’s D7200, if change of lens is not recommended at the location due to weather conditions.
Thank you again for all your comments and Merry Christmas.
