For photographers who have embraced the beauty of medium format film, the Zenza Bronica SQ-Ai stands as a beloved choice.
However, a common question arises among its users—can you use 120 film in a 220 back? This blog dives into this very query, offering insights and guidance to film enthusiasts eager to explore the possibilities.
Understanding Film Types
What is 120 Film?
120 film is a popular medium format film used widely across the world. Known for its versatility, it provides a range of aspect ratios, making it a favorite among professional photographers.
Its availability remains strong, with many manufacturers continuing to produce a variety of stocks, from black and white to vibrant color emulsions.
The film’s backing paper is a crucial feature, offering protection and ease during loading—a characteristic that 220 film lacks.
What is 220 Film?
220 film, similar in width to 120, holds twice the amount of exposures due to its longer length. However, this comes at the cost of no backing paper except at the start and end, which can affect handling and protection.
Once favored for its capacity, 220 film has seen a decline in production, leaving photographers with limited options. This scarcity has led many to consider alternatives, such as adapting 120 film for 220 backs.
Can You Use 120 Film in a 220 Back?
Technical Feasibility
Using 120 film in a 220 back is technically feasible, though not without challenges. The primary difference lies in the pressure plate design.
A 220 back expects the thinner 220 film without backing paper, so using 120 film, which includes this backing, can cause tighter winding and potential spacing issues.
Photographers might notice misalignment of frames or increased tension as the film progresses through the camera.
Practical Considerations
Beyond technicalities, practical considerations must be taken into account. While image quality may not drastically suffer, the increased wear on the camera’s transport mechanism is a concern.
The Bronica SQ-Ai’s robust build can handle occasional use, but consistent practice might lead to mechanical strain. If attempting this adaptation, proceed with caution and understanding of the potential risks involved.
Steps to Use 120 Film in a 220 Back
Preparing the Camera
To begin, ensure your Bronica SQ-Ai is in optimal condition. Clean the film path and check the pressure plate for any signs of wear. This preparation minimizes the risk of scratching the film and ensures smoother operation.
Loading the Film
Loading 120 film into a 220 back requires attention to detail. Align the start mark of the film with the indicated point in the back—typically adjusted slightly earlier than normal to compensate for the differing lengths. Secure the film tightly to avoid any slack, which can affect frame spacing.
Shooting with 120 Film in a 220 Back
Once loaded, manage the film counter carefully. Expect approximately 12 exposures, rather than the 24 you’d normally get with 220 film. Pay close attention to the counter after frame 12 to avoid taking empty shots, which wastes time and film.
Unloading and Processing
Upon reaching the end of the roll, advance the film completely to the take-up spool before removing it from the camera. Handle the film gently to prevent light leaks or damage. Consult your local lab about any specific processing requirements, especially if the film was tightly wound.
Alternatives to Using 120 Film in a 220 Back
Purchasing a 120 Back or Insert
The most straightforward solution for using 120 film with the Bronica SQ-Ai is obtaining a dedicated 120 back or insert. These components are specially designed for the film type, ensuring proper alignment and tension.
While availability can be limited, checking online marketplaces and photography forums often yields results. Investing in the correct back not only simplifies the process but also protects the longevity of your camera.
Conclusion
The question of whether you can use 120 film in a 220 back for the Zenza Bronica SQ-Ai is layered with nuances. While it’s possible, photographers should weigh the pros and cons carefully.
Experimenting with this setup can unlock creative opportunities, but be mindful of the potential wear on your equipment. Should you choose to pursue this method, approach with patience and care.
FAQs
Can you use 120 film in a 220 film back?
Yes, but expect increased tension and potential spacing issues. It’s advisable to monitor film progression closely to prevent mechanical strain.
What kind of film does the Bronica SQ take?
The Bronica SQ series is compatible with both 120 and 220 films, provided you have the respective film backs or inserts.
Is 220 the same as 120 film?
Not exactly. While both are medium format films, 220 is longer and lacks the protective backing paper, traditionally offering more exposures per roll.
Can I use 120 film in a 116 camera?
120 film is not directly compatible with 116 cameras due to size differences. However, modifications and adapters might allow its use in certain situations.
