Using 120 film in a 620 camera requires modifying the 120 film spool to fit the narrower 620 spool size. While technically not “shooting” 120 directly, the process involves respooling or physically trimming the 120 spool so it can be loaded and function properly within the 620 camera body.
Understanding the 620 Camera and Film Format
The 620 film format, popular in the mid-20th century, was essentially 120 film on a narrower spool. Cameras designed for 620 film have a film chamber that accepts only these slimmer spools. While 120 film remains readily available, 620 spools are not, leading enthusiasts to adapt modern film for use in their classic cameras. Understanding the nuances between the formats is crucial before attempting any modifications. The flanges of the 120 film spool are larger than those of the 620, preventing the spool from fitting into the 620 camera’s film compartment.
Methods for Adapting 120 Film
There are several methods for adapting 120 film for use in a 620 camera. Each method has its own set of advantages and disadvantages, ranging from relatively simple techniques to more involved procedures. Choosing the right method depends on your comfort level, tools available, and the value you place on preserving your original 620 spools.
Method 1: Respooling
Respooling involves transferring the 120 film onto an empty 620 spool in complete darkness. This is arguably the safest method for your camera as it doesn’t involve any physical alterations to the film itself.
Steps:
- Obtain an empty 620 spool. These can sometimes be found at camera shows, online auction sites, or by having film developed and requesting the empty spool back.
- Darkroom Setup: Work in a completely dark room. A changing bag or tent can also be used. Practice handling the film and spools in the light first, so you know what to do in the dark.
- Loading: In total darkness, carefully unroll the 120 film from its spool. Attach the end of the film to the empty 620 spool.
- Winding: Wind the film tightly and evenly onto the 620 spool. This process requires patience and a steady hand to avoid creases or light leaks.
- Securing: Once the film is completely transferred, secure the end of the film to the 620 spool with tape.
- Loading into the Camera: Load the respooled 620 film into your camera as you would normally.
Method 2: Spool Trimming
This method involves physically trimming down the flanges of the 120 spool so it fits into the 620 camera.
Steps:
- Acquire necessary tools: You will need a sharp craft knife or a pair of robust scissors, and potentially sandpaper or a file for smoothing rough edges.
- Careful Trimming: Carefully trim the edges of the 120 spool flanges. Trim a little at a time, frequently testing the fit in the camera until it fits snugly but not too tightly. Aim for an even reduction across the flange.
- Smoothing: After trimming, use sandpaper or a file to smooth any rough edges to prevent scratching the inside of your camera.
- Loading into the Camera: Load the trimmed 120 film spool into your camera.
Caution: This method carries the risk of damaging the film spool or the camera if not performed carefully.
Method 3: The Frankenspool (Less Recommended)
This method involves combining parts of a 120 spool and a 620 spool. This is generally not recommended due to potential complications and structural weaknesses.
Steps (not recommended for beginners):
- Carefully separate the end caps from both a 120 spool and a 620 spool.
- Attempt to attach the 620 end caps to the 120 spool. The fit might be imperfect and require glue or additional modification.
Problems: This method is prone to failure and can potentially damage your camera if the modified spool falls apart inside. The reliability is questionable, so it is better to stick with the respooling or spool trimming method.
Important Considerations
- Practice: Before loading an entire roll of film, practice the chosen method with a spent roll to get comfortable with the process.
- Darkness: When respooling, ensure complete darkness to avoid light leaks.
- Cleanliness: Keep your work area clean to prevent dust and debris from contaminating the film.
- Spool Integrity: Inspect the 620 spool for any damage before use. A cracked or damaged spool can cause problems inside the camera.
- Tension: Maintain consistent tension when winding the film onto the 620 spool to prevent loose rolls and uneven frame spacing.
Frequently Asked Questions (FAQs)
FAQ 1: Will respooling damage my film?
Respooling carries a small risk of scratching the film if not done carefully. Cleanliness and a smooth winding technique are key to minimizing this risk. Using gloves can also help prevent fingerprints.
FAQ 2: Where can I find empty 620 spools?
Empty 620 spools are becoming increasingly rare but can sometimes be found online (eBay, camera forums), at camera shows, or by asking your film lab to return the spool after development. Consider building a collection over time.
FAQ 3: Can I reuse the 620 spool after development?
Yes, absolutely. This is highly recommended to build up a supply of usable spools. Always request the empty spool back from your film lab.
FAQ 4: Is there any way to avoid modifying the film or spools?
Unfortunately, without using 620 film (which is not readily available), you must modify either the film spool or respool the film itself. No direct drop-in solutions exist.
FAQ 5: How do I ensure the film is wound tightly enough on the 620 spool during respooling?
Apply gentle but consistent tension while winding the film. Avoid jerking motions. Regular and even winding is much more important than extreme tension.
FAQ 6: What happens if the modified spool doesn’t fit properly in my camera?
If the spool is too tight, it might not rotate freely, leading to uneven frame spacing or even camera damage. Stop immediately and re-evaluate the modifications. If the spool is too loose, the film transport mechanism may not function correctly.
FAQ 7: What tools are essential for trimming 120 spools?
A sharp craft knife or strong scissors are the most important. Sandpaper or a file is useful for smoothing rough edges and preventing scratches inside the camera.
FAQ 8: What are the risks of using a “Frankenspool”?
“Frankenspools” are inherently unstable and can fall apart inside the camera, causing jams or even irreparable damage to the film transport mechanism. Avoid them if possible.
FAQ 9: How do I know how much to trim off the 120 spool?
Trim a small amount at a time and test the fit frequently. It’s better to trim too little and go back for more than to over-trim, which can make the spool unusable. The difference in flange diameter is quite subtle.
FAQ 10: Are there any special considerations when shooting in hot or humid environments?
Humidity can cause the film to swell slightly, potentially making the spool tighter in the camera. Avoid over-tightening the film when respooling. Extreme heat can also affect film performance.
FAQ 11: Can I use plastic 120 spools instead of metal ones?
Plastic 120 spools are generally easier to trim than metal spools. However, some cameras may only be compatible with metal spools due to the way the film advance mechanism works. Check your camera’s manual.
FAQ 12: Is there a company that still makes 620 film?
Unfortunately, no major manufacturer currently produces 620 film. Your only option is to adapt 120 film using the methods described above.
