How to Test a Second-Hand Camera Before You Buy (Online Edition)
Most of my favorite cameras came to me through the mail. Taking a chance on an eBay listing or a scrolling through Facebook Marketplace is thrilling, but my god, it can also be incredibly stressful. I've previously written a flea market checklist for when you can actually hold a camera in your hands, fire the shutter, and look through the viewfinder yourself. But what happens when you're buying a camera online? You can't touch it. You can't hold the lens up to the light to check for fungus. You just have to trust a stranger on the internet and a handful of heavily compressed JPEGs.
It took a few painful (and honestly, quite expensive) mistakes for me to figure out how to safely navigate the online used camera market. I once bought a "near mint" SLR that arrived sounding like an asthmatic goose every time I fired the shutter. Since then, I've developed a pretty strict system for evaluating online camera listings. Here is exactly what I look for, the specific questions I always ask, and the glaring red flags that tell me to keep my money and walk away.
Decode the Listing Photos Like a Detective
The photos are your first line of defense. The problem? Most people are genuinely terrible at taking pictures of cameras—which is heavily ironic when you think about it. When you're zooming in on a listing, don't just look at how pretty the camera is. You need to look for what the seller isn't showing you.
- The Bottom Plate: If there are no clear pictures of the bottom of the camera, ask for them. That is where all the tripod scratches, scuffs, and impact dents live. A heavy dent on the bottom plate isn't just a cosmetic issue; it can actually misalign the internal film advance mechanism.
- The Battery Compartment: I always try to zoom in closely on the battery door. If I see green or white crust creeping around the metal contacts, that is a clear sign of acid corrosion from an old, leaky battery. Corrosion can permanently fry a camera's electronics, which is an absolute death sentence for point-and-shoots.
- The Light Seals: On vintage analog SLRs, take a really close look at the grooves around the film door if the seller provides an open-back photo. If the original black foam looks sticky, crusted over, or completely scraped out, you'll need to replace the light seals. It's an easy and cheap fix to do at home, but you definitely want to know about it before you buy.
- The Glass: Sellers love taking pictures of lenses straight on. This looks nice for the listing, but it completely hides internal scratches and haze. You want to see pictures taken at an angle with a light reflecting off the actual glass elements.
Translating "Seller Speak"
Reading the description of a vintage camera listing is basically an exercise in translating a second language. After years of doing this, I've realized that certain buzzwords have very specific underlying meanings in the used market.
The biggest and most dangerous offender is the word "untested." Let me be totally straight with you: about 80% of the time, "untested" actually means "I put a battery in it, it didn't turn on, and now I'm pretending I don't know how cameras work so I can sell it to someone else." If you are looking at an untested camera, you need to assume it is entirely broken and bid accordingly. It is just a display piece or a parts donor until proven otherwise.
Then you have "mint condition." In the high-end camera collecting world, mint means the camera looks like it rolled off the assembly line twenty minutes ago. But on a random online marketplace? "Mint" usually translates to "it looks kind of clean and I wiped the dust off with a napkin." Pay close attention to words like "brassing" (which just means the black paint has worn down to reveal the brass body underneath—I actually love this look, it adds character) or "balsam separation" (a complete dealbreaker where the glued glass elements in a lens are physically peeling apart).
Questions You Actually Need to Ask
Never be afraid to send the seller a direct message. A trustworthy seller will be happy to answer your questions. A sketchy seller will get defensive or ignore you completely—which is your cue to close the tab. I never just pop into a chat and ask, "Does it work?" It is too broad and gives them the perfect opportunity to just say "Yes" without actually testing anything. I always ask specific, targeted questions.
- "Have you run a roll of film through it recently?" This is the golden question. A camera can wind and fire perfectly when it's empty, but if the internal film advance gear is stripped, it will jam up and shred your film the second there's actual tension from a roll.
- "Does the flash fire, and does the ready-light turn on?" Point and shoot cameras have their own specific risks. Because they are electronic, when they die, they're dead. The flash capacitor is a super common failure point on 90s compacts. If the camera winds but the flash doesn't fire, pass on it.
- "Are there any dark spots, haze, or spiderweb-like shapes inside the lens?" This forces the seller to actually hold the lens up to the light. Spiderweb shapes indicate fungus, which will ruin image contrast and is notoriously contagious to the other clean lenses in your camera bag.
- "Do the slow shutter speeds sound right?" If you're looking at a mechanical SLR, ask this. A very common issue is that the slow speeds (like 1 full second or 1/2 of a second) will drag or stick open completely due to sixty-year-old, dried-up lubricants inside the mechanism.
Spotting the Glaring Red Flags
There are a few situations where you should absolutely back away slowly. Stock photos are my absolute number one dealbreaker. If I search for an Olympus Mju II and the listing uses a cleanly lit, white-background photo pulled straight from a Google image search, I'm out. I want to see the exact, physical item I am spending my hard-earned cash on.
Another massive red flag is a seller who refuses to provide a quick video. If I'm dropping a decent chunk of change on a camera, I usually request a quick ten-second clip of them firing the shutter and winding the film advance lever. Almost everyone has a smartphone now; this takes literally thirty seconds to do. If they reply that it's "too much of a hassle," it usually means they are hiding a fatal flaw.
When the Online Hunt Gets Exhausting
Look, I'll be the first to admit that hunting for used equipment online is a mixed bag. It can be super fun when you score an amazing deal on a rare rangefinder, but it is also incredibly exhausting to sift through blurry, poorly lit photos and message people who only reply once every three days. Sometimes, you just want a camera that you know is going to work perfectly the moment you take it out of the shipping box.
