Nikon D500, D850, D7200 (and a few older models).
The 28-300 that normally lives on the D850 has been doing "interesting" things - The autofocus mostly works, but the information on focus distance is all over the place. Pointing at the same subject that may be 20 feet away, one time it'll read 10 meters, another 3 or 5, and so on. For something very far away, it will most likely STILL be 10 meters or 3 or something in between. When shooting at night and using the focus dial to manually set the lens to infinity, I'm not sure where it's focusing, but it fer SHER isn't infinity.
Occasionally, it THINKS it's autofocused, but through the view finder it's clearly not focused on what it's aimed at.
SO, off it went to Nikon 11 days ago. UNFORTUNATELY, I can't find the original invoice, so though I know it's less than 5 years old, Nikon is going to charge for the repair.
Today I figured I'd best call service and see when they'd have an estimate. And found out you CANNOT CALL NIKON SERVICE any more.... And the phone answerer at the only number they publish says "WE don't have a number for Nikon service and CANNOT CONTACT THEM".
A few minutes ago, an email came in wanting me to authorize the $300 repair (no details of course telling me WHAT they'll be doing for $300) and provide a credit card number AND THERE'S NO WAY TO CONTACT REPAIR DIRECTLY ON THE REPAIR AUTHORIZATION EITHER! Back to the same 800-645-6687 number, wait for a phone answerer, give them the information, hope it gets to repair in a timely manner, and that repair gets this thing fixed reasonably quickly
Its been a few years, but in the past I've been able to contact Nikon Service in Ronkonkoma and get an actual LIVE HUMAN on the phone, tell them what was going on (and how critical it is - as in when your D810 does a firmware update and turns itself into a brick, it's fairly critical), and make arrangements for the equipment to be fixed... Sent images to show them what was happening, had them call me, and so on.
This current system sucks. I expected better from Nikon, though these days I guess it shouldn't be a surprise.
