The camera fires once. Check the system you are actually selling

A camera is a system, and you are selling one specific slice of it

When a buyer looks at a used camera listing, they are not buying a box that takes pictures. They are buying into a system: a body with a particular lens mount, lenses that fit that mount, batteries and chargers that fit the body, memory cards the body can read and sometimes flashes, grips and adapters. A listing that says "camera works" while the kit inside the box will not actually function together is a return waiting to happen.

The good news is that cameras are unusually easy to describe well. They have clear model names, visible mount types, removable batteries and a screen that will show you what they captured. Ten minutes of careful identification is worth more than any adjective.

Step 1: Identify every component separately

Write each of these down from the item itself, not from the box or the previous seller's listing:

• Body: brand, model and any version or revision marking, plus the serial number for your private records.
• Lens: full designation (focal length, maximum aperture, any series or version markings) and its mount.
• Battery: model number printed on the battery.
• Charger: model number, and whether it matches that battery.
• Accessories: strap, caps, hood, memory card, cables, manual, box.

Then confirm compatibility through the manufacturer's information. Similar brand names or an attached third-party adapter do not establish that autofocus, aperture control or image stabilization will work. A lens from a different mount family, held on with an adapter, is a separate thing to describe.

A missing charger changes the buyer's practical cost even if you used your own compatible charger for the test.

Step 2: Inspect without dismantling

Look at the body, mount, battery door, card door, screen and controls under good light. For the lens, look through it toward a bright light (never the sun) and note haze, fungus-like filaments, dust, scratches and separation, as far as you can actually see them. Check that the focus and zoom rings turn smoothly and that the aperture blades, if visible, look clean and dry.

Do not open the body, clean the sensor with tools you have not used before or attempt internal lens cleaning to justify a better description. Unresolved optical or internal issues should be written as unresolved.

Step 3: Test the functions you can name

Charge the battery with a compatible charger and run through the functions this camera actually has. Keep each one a separate observation:

1. Powers on and the screen or viewfinder displays.
2. Takes a photo; the photo saves to the card and plays back.
3. Autofocus acquires focus with the included lens (if it has autofocus).
4. Aperture changes are reflected in exposure.
5. Each button and dial responds.
6. Video records and plays back (if offered).
7. Each port you can test with your own equipment.

Take a few sample images at different settings and keep them; a sample photo shows that a specific operation happened under those conditions. It is not a professional service report.

Some cameras can report a shutter count through menus or software. If you include one, say how you obtained it, and do not turn it into a lifespan guarantee.

Worked example: one output, four unanswered questions

In the chosen example, the camera makes one image. Lens compatibility, battery reliability, card-slot behavior and an external port remain unassessed. The one photo answers one narrow question; it does not clear the other four.

An hour per camera is a planning assumption, not an industry average. Multiply it across a camera bag full of accessories before you call the bag a bargain.

Step 4: Price the kit you can send

Search sold listings for the same body plus the same lens, or price body and lens separately when the kit is unusual. A body-only sale, a kit with the original lens and a kit with an adapted third-party lens are different comparisons. Note shutter-count or cosmetic differences where comparable listings report them.

Check the exact models against current recalls, and be ready to answer one common question honestly: "Does it come with a charger?"

Step 5: Wipe, pack and ship within the battery rules

Remove your memory card, or format any card you are selling after copying off anything personal. Reset the camera's settings, and remove any wireless pairing or account links if the camera supports them.

Most camera batteries are lithium-ion. USPS Publication 52 sets specific requirements for lithium batteries and for batteries installed in or packed with equipment, and those rules depend on configuration. Read the current section and the used-electronics shipping guide before choosing a label. Cap the lens at both ends, protect the screen, stop components from touching or moving and weigh the finished parcel.

Common mistakes:

• Photographing a lens on the body with an adapter and not saying so.
• Shipping your personal memory card.
• Writing "lens is clean" without having looked through it toward a light.
• Promising a shutter life from a count.

Describe a tested operation, not a complete performance promise. Price the body, lens and actual accessories as the supported kit you can send.
