How To Test A Film Camera (SLR) To Ensure It’s Working Properly

Updated: Aug 10, 2023

Testing a film camera thoroughly before purchasing it is essential to ensure proper working condition. Some of the terms used may not be familiar to you, if that's the case I encourage you to take the time to familiarize yourself by looking them up. Here's a step-by-step breakdown of how to test a film camera:


1. Inspect the exterior: Examine the camera body for any physical damage or signs of wear. Check for dents, scratches, loose parts, or missing screws. Ensure that the camera's buttons, dials, and switches are intact and functioning properly.


2. Check the lens mount: Inspect the lens mount to ensure it is clean and undamaged. Look for any signs of rust or corrosion. Attach and detach a lens (if available) to ensure smooth and secure mounting.


3. Test the shutter: Set the camera to the manual mode and fire the shutter at various speeds (including the fastest and slowest settings). Listen for any irregular sounds such as excessive noise, sticking, or delay. Verify that the shutter curtains move smoothly and consistently across the frame.


4. Check the aperture mechanism: Set the camera to the widest aperture (lowest f-number) and gradually close down the aperture to the smallest setting. Observe the blades for proper movement and smooth operation. Ensure the aperture stops down correctly at each setting.


5. Assess the viewfinder: Look through the viewfinder to ensure it is clear and free of debris or fungus. Check for any visible damage, such as cracks or scratches. Verify that the viewfinder displays information correctly (if applicable) and that the focusing aids, like split-prism or microprism, are functioning.


6. Test the focusing mechanism: If the camera has autofocus, activate it and ensure that it focuses accurately and quickly. If it is a manual focus camera, turn the focus ring and verify that it moves smoothly and accurately. Look for any resistance or looseness in the focusing mechanism.


7. Check the light meter (if available): If the camera has a built-in light meter, power it on and check if the readings change according to different lighting conditions. Compare the meter readings with a handheld light meter or a smartphone light meter app to ensure accuracy.


8. Test the film winding mechanism: Load a test roll of film (preferably an inexpensive one) and advance the film through a few frames. Ensure that the film advances smoothly and consistently with each winding action. Check if the film counter increments correctly.


9. Verify the self-timer: Set the camera's self-timer and ensure that it functions correctly. Check if the self-timer delay is accurate and consistent.


10. Look for fungus or debris in the lens: Remove the lens from the camera body and inspect it for any signs of fungus or debris. Hold the lens up to a bright light source (e.g., a lamp) and check for any visible spots or haziness inside the lens elements. Fungus appears as cloudy or web-like formations. A foggy or hazy lens can result in low contrast images.


11. Test additional features: If the camera has additional features like multiple exposure mode, exposure compensation, or various shooting modes, test them to ensure they work as intended.


12. Evaluate the test shots: After testing the camera's basic functions, review the images captured during the test roll. Check for proper exposure, focus accuracy, and overall image quality. Look for any unusual artifacts, light leaks, or inconsistent performance.



By following these steps, you can thoroughly test a film camera and assess its condition before making a purchase, ensuring that you get a reliable camera that meets your needs.
