Buying my first used camera what should I be checking before I pay?
Seeking opinions on buying from individual buyers/sellers. Appreciate any input.
(P.S. Couldn't find a buying advice post on the forum)
Also looking for advice on the same, especially for online transactions.
What are the non-negotiables that should be checked before finalizing the deal? Shutter count, autofocus in photo and video, sensor cleanliness, whether all buttons and dials work - are few which come to my mind. What else?

Add burst mode + a good visual inspection of the camera for dings, dents, etc.
If buying in person I would just use the camera as I plan on using it to make sure everything is working.
If buying online do the above as soon as you receive the camera.
On the few occasions I have sold a camera, I invited the buyer to come and test the camera. If in person testing is not possible I take a few videos showing the camera condition, the workings, and send it to the buyer.
- Physical condition: Minor paint peeling and scratches are fine. Avoid major dents or signs of drops, abuse or water damage.
- Sensor: Check for scratches, coating damage or image artefacts. Dust can usually be cleaned.
- Autofocus: Test AF-S, AF-C, eye AF and subject tracking, if available.
- Shutter and burst mode: Test different shutter speeds, continuous shooting and buffer performance.
- Buttons and dials: Check every button, dial, touchscreen and menu.
- Back-button focus: Assign AF to a rear button and verify it works.
- Card slots and ports: Test all SD/CFexpress slots, USB, HDMI, microphone and headphone ports, as applicable.
- IBIS and lens mount: Check image stabilisation, mount condition and lens communication.
- Display and EVF: Look for dead pixels, flickering and damage.
- Shutter count: Check using a compatible tool, but don't judge condition on count alone.
- Battery and connectivity: Check battery health, charging, Wi-Fi and Bluetooth.
- Test images: Shoot at different ISO levels and apertures; inspect images at 100% for lines, spots and unusual artefacts.
Many important points. I would also emphasise on getting the service history from respective OEM service centres. If you have the serial number and approach with a smile, they usually indulge you ( I have been lucky on that count), obviously off the record, and let you have the service history which often throws up surprises.

That is an excellent and useful hack, but there is a catch: an empty or clean OEM service history can be misleading.While a detailed record is great, the absence of one doesn't mean the equipment is flawless. In fact, it often points to a careless or stubborn owner who completely neglected maintenance or relied entirely on unauthorized, third-party fixes.For example - A machine with zero logged issues might look perfect on paper, but it usually just means it hasn't seen a professional technician in years.
- Stubborn users (who proudly proclaim "never needed repairs") frequently skip needed maintenance entirely, meaning wear and tear goes completely undocumented.
- Careless owners often patch up critical failures using cheap, unauthorized local mechanics just to keep the machine running until they can sell it. WhatsApp groups are full of queries asking about "trusted" (but not authorized ) repair people
Ultimately, a spotless OEM record is only helpful if it proves regular, scheduled maintenance happened—not just that the machine managed to stay out of the official shop
Always important to remember what Carl Sagan said : absence of evidence is not evidence of absence.

How often does the average camera need professional maintenance? I have
never once heard of anyone taking their camera for such a thing, except for those who are scared to clean their own sensor.
Maybe really heavy users such as professional sports cameramen?

Personal anecdotes and service records only show what gets reported, not the actual health of cameras out in the wild.Relying on that data to judge reliability leaves a few blind spots:- Plenty of users live with minor bugs, slightly misaligned autofocus, or sticky dials without ever sending the camera in. Zero service history usually just means the owner found a workaround.
- Invisible maintenance: A lot of gear is fixed via third-party local shops after warranty ends simply because it is the cheaper option
- Pro vs. Hobby Users: You're right about heavy users. Sports shooters, wedding pros, and rental houses (especially them) heavily use their gear and run it through regular maintenance cycles that the average hobbyist never even thinks about.
At the end of the day, service logs track repair behavior, not how many cameras are actually running perfectly behind the scenes.
Edit: When they come on to the second hand market both heavily used "pro" equipment and lightly used "hobby" equipment swim in the same pool. That poses a bit of a challenge for the prospective buyer

Or gear that see less use. For instance nikon 500 and 600 f4 primes suffer dead motors if they are lying unused for prolonged periods.
Yes, I live with a minor bug in my Sony A7iv: sometimes it gives two clicks for one shutter push. And it's out of warranty now so I probably will never do anything about it.
But, without an actual fault that seriously affects usage, I have no plans to take my camera(s) for "maintenance." In fact, unless it has to be taken apart, I'd rather every screw remained in in its factory-set state.
We are hobbyists here. I don't think there are going to many maintenance trips: does anyone here actually do that? Not what good reasons might there be, but does anyone?

I've heard many cameras develop new issues after unnecessary services the official service centres. Cameras are not cars which require oil or filter change.

Interesting. Are there any verified reports or published examples of this happening, or is it mostly based on forum rumors? It would be good to know if any specific brands or centers have been documented doing this, or if it's just unverified speculation?

Response to the question "do you take your camera for preventative maintenance" is almost entirely
no. One person said, that belongs to some cameras for adjustment of shutter speed and lubrication.
Krish, do you?
Or is this whole thing another unjustified speculation ;)

I did not read any response saying anything either way. ,Where did you read that ?
Somnath suggested reading service history at authorized centers may be a good source of cross checking the stated condition
My point was that the records themselves may not present an accurate picture, whether that is due to either people not taking cameras for repair/maintenance or not taking them to authorized centers for repairs - where these records are maintained. No one knows accurately.
Your personal anecdotal experience suggests "no one takes their camera for preventive maintenance" Something you seem determined to establish.
Okay, maybe you're right. Now what? The OP still wants to know how to check and what to check while buying used cameras. What advice do you have for him?
Sorry, Krish. I got the identities of who was saying what mixed up there.
Not really trying to prove anything. I was taken aback at the suggestion of people doing regular services. Did a very small bit of asking around.
Yes indeed, only anecdotal.
