If you're not familiar with the equipment, it's a good idea to bring along someone who is, or to do some research before testing. 

If you find any issues while testing the equipment, ask the seller if they would be willing to fix them or lower the price accordingly. And always, be sure to check the return policy before making a purchase, in case the equipment turns out to be defective or not as described. 

Check the shutter count 

Shutter count is the number of times the shutter has been activated on a camera. It is an indicator of how much the camera has been used and can be used to estimate the remaining lifespan of the camera. A high shutter count can indicate that the camera has been heavily used, which could affect its performance and lifespan. 

The shutter count can be checked by using specific software like "Exif Pilot" or "Shutter Count" that reads the metadata of the image files taken with the camera and shows the shutter count. Some camera manufacturers also provide a way to check the shutter count directly from the camera's menu. 

It's pertinent to note that different cameras have different shutter life ratings, and the number of actuations they can handle before failure. For example, a professional-grade DSLR camera may have a shutter life of 150,000 to 300,000 actuations, while a point-and-shoot camera may have a shutter life of around 50,000 actuations. 

When checking the shutter count, it's important to keep in mind that a high shutter count doesn't always mean that the camera is near the end of its life. Some cameras may have been used less frequently or for shorter periods of time, which would result in a lower shutter count. 

It's always a smart idea to compare the shutter count with the expected lifespan of the camera to get a better idea of the camera's overall condition. And if the shutter count is too high for the age of the camera, it could be an indication of a problem and you may want to consider not buying it.
