How to Fix Sluggish Slow Speeds on a Copal Shutter

A Copal shutter is a popular choice for many photographers, but sometimes the slow speeds can become sluggish. This can be a frustrating problem, but it’s often easy to fix. In this guide, we’ll show you how to remove and service the slow speed escapement, bringing your Copal shutter back to its original specifications.

Understanding the Problem

Sluggish slow speeds on a Copal shutter are often caused by a buildup of dirt and grime. Over time, this debris can accumulate on the escapement mechanism, making it difficult for the shutter to operate smoothly. This can lead to inconsistent exposures and blurry images.

Tools You’ll Need

  • A small screwdriver set
  • A magnifying glass
  • A soft brush
  • A can of compressed air
  • A small container of cleaning fluid (such as lens cleaning fluid)
  • A lint-free cloth

Steps to Service the Slow Speed Escapement

  1. Remove the shutter from the camera. This process will vary depending on the specific camera model. Consult your camera’s manual for instructions.
  2. Locate the slow speed escapement. The escapement is a small mechanism located on the back of the shutter. It typically consists of a lever, a spring, and a set of gears.
  3. Clean the escapement. Use a soft brush and compressed air to remove any dirt and debris from the escapement. Be careful not to damage any of the delicate parts.
  4. Lubricate the escapement. Apply a small amount of camera oil to the pivot points of the escapement. Avoid using too much oil, as this can attract dust and grime.
  5. Reassemble the shutter. Carefully reassemble the shutter, making sure that all of the parts are properly aligned.
  6. Test the shutter. Once the shutter is reassembled, test the slow speeds to make sure that they are operating smoothly. If the slow speeds are still sluggish, you may need to repeat the cleaning and lubrication process.

Tips for Maintaining Your Copal Shutter

  • Clean your shutter regularly to prevent dirt and grime from accumulating.
  • Avoid using the shutter in dusty or humid environments.
  • Store your camera in a dry, dust-free place.
