Bronica Zenza ETR 135 back

Bronica Zenza ETR 135 Back

1. Purpose:

   • The 135 film back allows Bronica ETR series cameras (ETR, ETRS, and ETRSi) to shoot with 35mm film instead of the usual 120/220 medium format film.
   • This provides more flexibility and the ability to switch between different film formats without needing a separate camera.

2. Design and Features:

   • Construction: The 135 back is designed to attach securely to the back of the ETR series camera bodies, replacing the standard 120/220 film back.
   • Film Loading: It features a standard 35mm film loading system, similar to 35mm SLR cameras, making it familiar and straightforward for users accustomed to 35mm film.
   • Frame Size: The 135 back captures images in a 24x36mm frame size, standard for 35mm film.
   • Film Advance: The film advance mechanism is integrated into the back, ensuring smooth and consistent frame spacing.
   • Film Counter: Includes a film counter to keep track of the number of exposures.
   • Viewfinder Mask: A mask is often included to insert into the viewfinder, providing the correct framing lines for the smaller 35mm format.

3. Compatibility:

   • The 135 back is compatible with all Bronica ETR series cameras, including the ETR, ETRS, and ETRSi models.
   • It’s important to ensure the back is correctly mounted and that the camera body is compatible with the specific 135 back model.

4. Benefits:

   • Versatility: Allows photographers to use both medium format and 35mm film with the same camera body, providing greater flexibility in shooting.
   • Cost-Effective: 35mm film is generally more affordable and readily available than medium format film, making it a cost-effective option for certain projects.
   • Experimentation: Enables photographers to experiment with different film formats and types without needing multiple cameras.
