The Sunday flea market is full of old cameras. Some are worth 30 euros and some are worth 800. The difference is rarely in how they look — it’s in five details anyone can check in thirty seconds.
1. Look at the brand and model, not the look
A rusty Leica is worth more than a brand-new Praktica. Names matter: Leica, Hasselblad, Rolleiflex, Contax are serious surnames. Nikon, Canon, Pentax, Olympus had professional models with firm prices and entry-level ones now worth little. Note the exact model (M3, F2, OM-1, etc.) before judging.
2. Check the shutter at multiple speeds
If the camera has a mechanical shutter, it should sound clean at 1 s, 1/30, 1/250, and 1/1000. If it sounds slow, stuck, or irregular, it needs a service: 80 to 200 euros in a workshop. That changes your offer.
3. Inspect for fungus and lens separation
Hold the lens up to the light. If you see spider-web patterns or specks (fungus), or rainbow iris at the edges (cement separation), the lens is dead. For many cameras, the lens is 60% of the value.
4. Check for rare batteries
Some pre-1980 analog cameras use mercury cells no longer manufactured (PX625, PX13). There are adapters, but they add 25–40 euros and sometimes the meter loses accuracy. If the camera doesn’t work without that exact cell, factor it in.
5. Check that it works, seriously
A ‘collector aesthetic’ camera that doesn’t fire is worth half of the same camera that works. Ask to see the shutter. Fire it at different speeds. Confirm the film advance turns. If it doesn’t work and the seller says ‘easy fix’, deduct at least 80 euros for workshop time.
A quick second opinion
If you want a more objective bearing on the spot, Vunto compares your photo against recent real sales of the same make and model on eBay USA, Wallapop, Vinted, and Catawiki. In thirty seconds it gives you a fair price range for your area and tells you whether the one in front of you shows signs of being a good deal or not.
Summary
Five minutes in front of the stall: brand and model, shutter, lens, batteries, function. With that you already know whether the price they ask is ridiculous, decent, or a steal. And if you want a second opinion backed by market data, you take out your phone.
