LOL! I guess that kinda depends on your interests. I know some things are still getting action while others are seemingly stagnant.
I have some oddball tastes I admit.
Old military surplus small equipment with moving parts, the more the better, same with some automotive and farm, and some lab equipment. I make a few bucks with stock footage and just about everything now has logos and numbers all over. Here are some things.

I also go to most any kind of airshow, old car, old farm equipment, livestock, or anywhere that people will bring and show stuff off.
Photos are easy enough to fix but video is another animal. I’ve signed up for a trial of Adobe After Effects which is something I have no real idea how to use.
Apart from cover ups, my main problem is dust and grit on the sensor that shows up only after seen in normal view. It isn’t often since I routinely clean the sensor.
