5 Tests Before Buying a Film Camera

Buying your first film camera is always an exciting venture. Film is a fun and exciting venture for any photographer or photographer to be, and right now is the perfect time to get into it. But if you’re used to buying digital cameras, film is a completely different ball game with some extra considerations. 

For one, none of these cameras have a way to check the shutter count, so you can’t ever know how well used a camera is. On the same token, these cameras also break down in much different ways. If they’re coming from other, humid parts of the world, there’s always the fear that they’re going to have some mold or rust breaking them down from the inside. 

And sure, the cameras may look good, but it’s hard to pay over $100 and have so much pent up anticipation only for it to become a shelf ornament. So here are the 5 tests that you should always do before buying a film camera in person. But if you buy a camera on eBay, and it fails one of these 5 tests despite having a Mint+++++ description, send it back. 

For the most part, I’ve been very lucky when buying cameras, but I’ve learned to spot a few issues that typically spell doom for the camera in the short or long term. For all these tests, I recommend bringing a flashlight, but usually your phone light will do in most cases.

1. Check for battery corrosion

This is the first step, because it’s by far the most important. Older film cameras from the 60s and 70s typically don’t require a battery to operate. But many of the more modern cameras do require a battery for either just the light meter, or to operate entirely. But almost nobody is going to give you a fresh battery when you come to test the camera. If it requires a battery to operate the shutter, do not buy the camera without putting in a fresh battery.

So before you go take a look, research the camera and bring a proper battery. If they already have a working battery in the camera, then worst case you’ve got an extra. 

When you insert the battery, check the compartment for corrosion. If the camera was stored for 15 or 20 years with a battery inside, sometimes that corrosion can actually follow the wires into the camera, corroding the wiring from the inside out. If you see a lot of green inside the battery compartment, then this is likely the case and the camera light meter, or worse, the entire system, won’t be functional. 

Check to make sure the film advance lever and shutter are working properly.

2. Check the shutter mechanism and film advance

The second test that I always do is to check if the camera shutter fires. Most films cameras have a lever on the top right that you pull out, though some medium format cameras, like TLRs have a pop-out lever that you rotate to advance the film. 

Make sure it doesn’t feel like there’s something crunching inside when you advance the film lever. If it’s smooth, chances are everything is going as planned. Then release the shutter and listen for that click. 

Then, the next step is to open the camera back and repeat this test. Watch the shutter curtain to make sure it’s advancing properly, and that it actually opens and moves as intended. 

If something feels loose, or you run into any problems with the camera, it’s usually best to hand it back to the owner and move onto the next one. In some cases it’s possible to fix, but in others it can become a very costly venture. 

The light seals are in that lip where the silver meets black on this camera.

3. Make sure the light seals are intact

While you have the camera back open, this is the best time to check the seals. These seals  tend to break down with age, but you’ll need to do this test to make sure it’s safe to run a test roll through the camera. As if the light seals are bad, you could come back with a bunch of negatives that aren’t properly exposed, and have tons of light patches all over the place. When that happens, it’s hard to diagnose any other issues that could be occurring with the camera. 

So the best way to know if you need to replace the light seals is to check around the back casing near the edges of the camera. If there are a lot of thick, gooey black spots everywhere, the entire camera will need to be cleaned and resealed. This job is fairly easy to do yourself, but it’s typically advisable to send a camera like this to a professional for a CLA. This is a standard cleaning procedure that usually needs to be completed every 10 years, where a technician will clean out any gunk and re-lubricate the camera shutter. Usually adding a light seal replacement to a CLA job should be fairly cheap. 

The shutter will stay open in bulb mode, allowing you to take a look around the whole camera.

4. Set it in bulb mode and look inside the camera for mold or fungus

This test is really important. It’s where you’re going to look around the camera and really see how well it’s been taken care of. Take the lens off the camera, set the camera to bulb mode, and take a look around the camera with the flashlight on the back of your camera. Bulb mode keeps the camera shutter open until you release the shutter button. If you have trouble holding it down, it can be a good idea to purchase a shutter release cable, like this one on Amazon, that will allow you to lock the shutter open. 

Once it’s open, use your flashlight to look around the inside of the camera. Look for rust, scratches, mold, fungus, or anything that looks like the camera degrading from the inside. If you can see some rust or mold here, there’s also likely the same thing clogging up the camera mechanisms. 

If you’d like to learn how fungus can ruin image quality as well as the resale value of your camera gear, check out this article. Fungus is no laughing matter. I’d absolutely recommend passing up any camera body that shows even the smallest amount of fungus. In some cases, it can even spread to other camera bodies and lenses, making it an absolute blight on your camera gear.

While you’re looking inside the camera, check these signs

Next, release the bulb mode, and watch how well the shutter closes. If it’s slow to close on one side, that could mean that the images will be darker on one side than the other — a difficult problem to fix in post or in the darkroom. 

At this stage, I also always check the camera shutter for light leaks. If it’s a cloth shutter, they sometimes develop holes over time. Place the light from your flashlight over the back of the camera when the shutter is closed, and look through the front of the camera. If you press it against your face to cover the outside, you shouldn’t see any light. If you do find a bit of a leak, it’s an easy fix with a light touchup of liquid electrical tape, like this one on Amazon. Let this tape dry as per the instructions on the bottle so it doesn’t clog up the shutter curtain area and do more damage to the camera. But a small amount will completely fix the problem.

Use the 1 second shutter speed if the camera has it, to test if the speeds are accurate.

5. Test the slow shutter speeds

After you’ve ensured the camera is clean, the next step is to look at how accurate the shutter speeds are. One the mechanical cameras, it’s always the slower shutter speeds that break down over time. Most of them use spring tension, so if the camera was stored improperly, that tension may change the speed. 

The best way to test the shutter speed is usually to look for the 1 second speed. If the camera doesn’t have a 1-second timing, then use the slowest timing available. 

Cock the shutter, and set up a stopwatch on your phone. Let it run, and when you feel comfortable, release the shutter and count how long the 1-second shutter speed takes. If it’s off by 1/10 of a second, it won’t be an issue. But if it’s off by 1/20th or 1/30th of a second, your exposures will be inaccurate at the slower speeds. 

This problem isn’t a cheap or easy fix. Typically if it’s off by too much, the best bet is to leave the camera behind. 

So there you have it! Are there any tests that you make sure to do every time? Let me know in the comments below, or post about it on the official Learn Film Photography Facebook Group!
