How to test a film camera: a simple step-by-step guide

Vintage cameras hold a timeless charm, but before putting them on display or loading film, it’s wise to check if they actually work.

If you’ve ever wondered how to test a film camera — especially a mechanical one like the Baldina — this simple checklist will walk you through it. No film required.

1. External condition

Inspect the body. Any dents, cracks, or rust? Hold the bellows up to light — if light leaks through, it may have pinholes that can ruin film.

2. Shutter and release

Wind the film lever (or simulate winding), then press the shutter. Does it fire with a "click"? Try different shutter speeds — do the slower ones last longer than the fast ones?

3. Lens and focus

Look through the lens. Is it clean or foggy? Does the focus ring turn smoothly? Open the aperture fully and change the f-stop — does the aperture size change inside?

4. Film transport and internals

Try turning the film advance knob and open the back if possible. Do things seem intact? If there’s a rangefinder, check if the double image aligns properly when focusing.

5. In summary

If the shutter fires, the aperture responds, and the lens is clear, the camera might still be usable — or at the very least, it's a worthy display piece for collectors.
