I like a wide angle ..the 14mm Samyang on the D850 is my favorite but I recently bought two Sigma 10-20mm on a 20% off from Camera Jungle and sold both on ebay for a good proffit .Then I spotted the Nikon AFP 10-20mm at a very good price . Furthur investigation shows that it wont work on my old D3200 ( I keep one camera out the safe for easy use ..I call it Crap Cam) or my low shutter count D7200 so I am thinking hey my cameras are being made obsolete. New nikon lenses will be AF-P. Going back to the D40 and up all the cameras will work with "old style" DX lenses but not now . I have been screwed by Nikon. Where do I go before my bodies become doorstops...D3500? No good for birds . So I am stuck with either a D7500 ,20mp and one SD or a D500 again 20 MP . Totally Screwed.
