The short answer is no, not directly. 620 film, while the same width as 120 film (the standard medium format), is wound onto a thinner spool. This difference in spool thickness prevents it from fitting properly into most medium format cameras designed exclusively for 120 film. However, all is not lost; workarounds exist, but they require modification or adapting the film.
Understanding the 620 Film Format
The 620 film format was introduced by Kodak in 1932 as an alternative to their widely successful 120 format. The primary reason for its creation was to allow for the design of smaller and lighter cameras. The thinner spool allowed for a more compact film path. While the film width (6.1cm) remained identical to 120, the spools were significantly different.
The 620 spool features a smaller flange diameter than the 120, as well as a thinner core. This seemingly small difference, however, means that 620 film spools are generally incompatible with cameras designed for 120 film. Cameras designed specifically for 620, like many older Kodak Brownies, will only accept the 620 spool.
Workarounds: Adapting 620 for Medium Format
While a straight swap is impossible, resourceful photographers have developed several methods to use 620 film in cameras designed for 120. The most common strategies include:
Respooling 620 Film onto 120 Spools
This is the most practical and widely recommended method. It involves carefully transferring the 620 film onto an empty 120 spool in complete darkness. This process requires a darkroom or a light-tight changing bag. You’ll need a spare 120 spool, the 620 film roll, and some patience. After respooling, the 120 spool containing the 620 film can be loaded into a 120 medium format camera as usual. Be meticulous in the dark; any light leaks will ruin your images.
Adapting 620 Spools to Fit
Some photographers have attempted to modify the 620 spools to fit into 120 cameras. This often involves filing down the edges of the 620 spool to reduce its flange diameter. This method is risky, as it can damage the spools and potentially the camera mechanism. It also requires precise and even filing to ensure smooth film transport. Furthermore, the resulting spool might still not be a perfect fit, leading to uneven winding or jamming. This approach is generally not recommended due to the high potential for damage.
Using Adapters (Rare)
While not widely available, specialized adapters designed to allow 620 spools to fit into 120 cameras have been manufactured. These adapters essentially fill the gap created by the smaller 620 spool. However, finding these adapters can be challenging, and their effectiveness varies depending on the specific camera model. They are a good solution if you have access to them and trust their quality.
Why Bother Using 620 Film?
The primary reason photographers seek to use 620 film is its availability in certain discontinued emulsions. Some films were exclusively manufactured in the 620 format, making them desirable for those seeking a specific look or aesthetic. Another reason is that you may have inherited a camera loaded with the film, or have otherwise acquired rolls that you want to use.
While modern 120 films offer a wide range of choices, the appeal of vintage emulsions remains strong for some photographers.
FAQs About 620 Film and Medium Format
Here are some frequently asked questions that further clarify the complexities of using 620 film.
1. What is the key difference between 120 and 620 film spools?
The diameter of the spool flanges and the thickness of the spool core. The 620 spool has smaller flanges and a thinner core, making it smaller overall than the 120 spool.
2. Can I rewind 120 film onto a 620 spool?
Yes, you can. In fact, this is often necessary when using a camera originally designed for 620 film. Once you’ve finished a roll of 120 film, you can rewind it onto an empty 620 spool for use in these cameras.
3. What tools do I need to respool 620 film?
You’ll need a darkroom or a light-tight changing bag, a 620 film roll, an empty 120 spool, scissors (optional), and possibly some tape. Ensure your workspace is completely dark to prevent light leaks.
4. Is respooling 620 film difficult?
Respooling requires patience and careful attention to detail, but it’s not inherently difficult. The key is to ensure a completely dark environment and to wind the film tightly and evenly onto the 120 spool. With practice, it becomes a relatively straightforward process.
5. Will using an adapted 620 spool damage my 120 camera?
There is a risk of damage if the adaptation is not done correctly. Uneven filing or poorly fitted adapters can cause the spool to bind or jam, potentially damaging the camera’s film transport mechanism. It’s generally safer to respool the film.
6. Are there any cameras that accept both 120 and 620 film without modification?
Very few cameras are designed to accept both formats without modification. It’s always best to consult the camera’s manual or research online forums to confirm compatibility before attempting to load a 620 spool.
7. Where can I find empty 120 spools for respooling?
Empty 120 spools are readily available. You can save them after finishing a roll of 120 film, purchase them from camera stores, or find them online. Many labs will also give them away.
8. What happens if I accidentally expose the film during respooling?
Exposure to light will ruin the exposed portion of the film. Even a brief exposure can create light streaks or fogging on the images. This is why respooling must be done in complete darkness.
9. Are there any labs that will respool 620 film for me?
Some specialized film labs offer respooling services. This is a convenient option if you’re uncomfortable doing it yourself or lack the necessary equipment. However, it’s usually more cost-effective to respool the film yourself.
10. Can I reuse 620 spools?
Yes, 620 spools can be reused indefinitely as long as they are in good condition and haven’t been damaged. It’s good practice to inspect them for cracks or bends before each use.
11. What are the dimensions of a 620 spool versus a 120 spool?
While exact dimensions may vary slightly depending on the manufacturer, the crucial difference lies in the flange diameter and core thickness. The 620 spool has significantly smaller flanges than the 120, typically around 31mm, and a thinner core. The 120 film flange is usually around 38mm.
12. Is there a way to easily identify 620 film without opening the packaging?
The packaging is the best way to distinguish. 620 film cartridges are typically marked very clearly with “620”. However, if the original packaging is missing, comparing the spool’s size to a known 120 spool is the easiest way to differentiate them. The smaller flanges of the 620 spool will be immediately apparent.
