Buying used camera gear can be a great way to save money, but it can also turn into a minefield if you don’t do your homework. In this video, I walk you through the exact checks I’d do before I even “hit the power button”—starting with the camera’s backstory. I’m looking for clues like original box, receipt, and accessories, because those usually tell you how the gear was treated. I also talk about why serial-number “service history” isn’t something you should rely on, thanks to manufacturer privacy policies. From there, I get into the big-ticket stuff: shutter count (think odometer), firmware version, and the physical inspection points people miss—lens mount damage, loose ports, battery compartment corrosion, and hot shoe issues. Then I show how to test real-world performance: autofocus behavior, video overheating/glitches, and quick dead-pixel checks. I also cover lens inspection basics (dust vs. scratches/fungus/haze) and the pricing reality: a “cheap” used deal can balloon once you factor repairs and missing accessories, sometimes landing you near new-camera pricing with none of the warranty safety.
