Polaroid Pronto RF - AAA battery and 600 film mod on a very special box camera

Introduction

Introduction

In this article, we'll dive into the refurbishment process of a Polaroid Pronto RF, a unique box-type camera with a built-in rangefinder and the capability to shoot various types of integral film. Enhancing its functionality, this camera can be modified to use both AAA batteries and 600 film, allowing for better versatility and practicality.

Overview of the Polaroid Pronto RF

The Pronto RF, often overlooked, is specifically designed with a variable focus lens, setting it apart from standard box-type models. This clever design incorporates a rangefinder, enabling precise focusing capabilities similar to an SX-70 camera. While it typically uses slow ISO 150/160 film, a conversion allows for the addition of AAA battery capability and 600 film use.

The Modification Process

Step 1: Dismantling the Camera

Before starting the mod, it’s essential to ensure the camera is fully functional. A preliminary test confirmed that the Pronto RF worked fine post-shipping from Baltimore to the modder. The disassembly process involves carefully removing the lens, electric eye, and reaching the internal components like the camera's capacitor.

Note: The very early models of the Pronto are sometimes compatible with parts from standard Pronto cameras, identifiable by a factory testing battery cut-out.

Step 2: Cleaning and Inspection

Upon opening the camera, the internals were found in pristine condition, almost as if it were new. It's crucial to clean the internal components to ensure optimal functioning after the mod.

Step 3: Capacitor Replacement

Here's where the main functionality improvement occurs. By swapping the original red 400 picofarad capacitor with a smaller 100 picofarad capacitor, the camera becomes compatible with 600 film. This step is critical for enhancing exposure accuracy.

Step 4: Wiring in the New Battery Pack

The modder will now wire in a new AAA battery holder. A toggle switch allows the user to choose between AAA batteries or the internal battery when using compatible film. Precise soldering and securing the wiring to avoid any short circuits are key here.

Step 5: Reassembly and Testing

After reassembling the camera, testing was conducted to verify that the modifications worked flawlessly. Sample photos showcased vibrant colors and accurate exposure, illustrating how successful the mod was.

Results

The final output results were gorgeous photos highlighting the camera's capabilities, particularly when modified. The mod also ensures that taking instant photos could now be achieved with greater ease and flexibility thanks to 600 film compatibility and AAA battery usage.

Conclusion

The Polaroid Pronto RF’s modification allows for a more versatile shooting experience. With the ability to use AAA batteries and 600 film, it makes this underrated camera a fun tool for instant photography enthusiasts. Careful handling and understanding of the camera's parts are vital for a successful mod.
