I am switching to Nikon Z mirrorless and needing to sell my high-end Nikon D-850 and lenses. They have served me well. Beautiful glass.

Nikon D850 - $1550
AF-S 24-70 2.8 - $850
AF-S 28-300 3.5-5.6 - $400 (Brilliant travel lens)
AF-S 50mm 1.4 - $300
AF-S 35mm 1.8 - $400
AF-S 85mm 1.8G - $250

The camera and all lenses are in excellent condition. The 24-70 lens got the most use and many of the photos taken are posted here on UHH. More than happy to answer any questions. Can take PayPal, Venmo

I am considering purchasing an older film Nikon from Japan — perhaps an FM3a or F3. Either would be old enough to be out of any original Warranty period; and, by definition, neither would be a ‘Nikon USA’ camera. Therefore am wondering about any future service needed.
Am I correct in assuming that:
1) Since they are not cameras imported to US by Nikon USA, Nikon USA would not provide any service to them, even if I paid them?
2). Also, for the same reason, Nikon USA would not provide the parts required for that service/repair on these cameras to an independent service business in the US?

If these two assumptions are correct — particularly for older Nikon cameras — how worried should I be about buying one? (They are not exactly inexpensive.). Or, are the above assumptions and potential concerns basically irrelevant?

Thanks in advance for any advice you can offer.

If you filter and count your images with 2021 shooting dates in Lightroom, what surprises do you find? Do you use your own usage statistics to plan to sell unused lenses / cameras? Or maybe, to change the lenses you'll use more in 2022?

Personally, when I sort / filter my 2021 statistics in Lightroom, I see have still have a lot of culling to do from the November travel and multiple architecture boat tours in Chicago in August. Picking the exact total winner isn't possible yet. What I do note, though, is a better and more equal distribution of lens usage through 2021.

Usage, that's really the idea of this annual review of images and lenses used. I don't own any lenses, (nor cameras) that are not actively being used. Most, of course, are not every day / every month. But all are now being used to create 'keeper' images every year. It is this annual review of usage that helped me a few years ago to get rid of underused equipment and to push a few lenses off the shelf and back onto camera bodies for more active use.

Preliminary results say the 600mm extended configuration of the EF 300 f/2.8L IS II and the EF 2x III teleconverter have moved back to the top place in usage as I've had more time / opportunities with wildlife in 2021 as compared to 2020. Again, the incomplete culling skews actual results, but of my four bodies and 5921 images in 2021 currently remaining, I see the EOS 5DIII still being used most and the more frequently lenses with image counts in the 300 to 500 range.
