I still use my old Nikon D700 for some things, like as a timelapse camera or for simple product shots.

The 12 megapixel sensor in the 35mm format is still much better at gathering light (without any fancy AI manipulation) than any modern small sensor camera, and the few Nikon lenses I still have around—one manufactured in the 70s—are extremely sharp and still great for many situations (though lens coatings, even on tiny sensors and smartphones, are vastly improved nowadays).
