Introduction
The Fotodiox Pro Soft Shutter Release Button is an accessory designed to enhance the ergonomics and functionality of cameras equipped with a standard threaded shutter release. Its primary purpose is to enlarge the contact surface of the shutter button, providing a more comfortable and stable point of activation for photographers. This design helps to minimize camera movement during the shutter release process, which can contribute to sharper images, especially during longer exposures or when precise timing is critical. It is particularly beneficial for classic cameras where the original shutter button may be small or less comfortable to operate.
Key features include simple installation on traditional threaded shutters and a smooth surface for an improved shooting experience.
Product Overview
The Fotodiox Pro Soft Shutter Release Button is a small, circular accessory made of metal, featuring a threaded post on its underside for attachment to compatible camera shutter buttons. The top surface is smooth and slightly convex, designed for comfortable finger placement. The silver finish complements various camera bodies, and some versions may feature branding on the top surface.

Installation
The Fotodiox Pro Soft Shutter Release Button is designed for straightforward installation on cameras equipped with a standard threaded shutter release button. Follow these steps for proper attachment:
- Locate the Camera's Shutter Release: Identify the threaded shutter release button on your camera. This accessory is compatible with traditional mechanical threaded shutter release sockets.
- Align the Threads: Carefully align the threaded post of the Fotodiox Pro Soft Shutter Release Button with the camera's shutter release thread.
- Gently Screw On: Turn the soft shutter release button clockwise. Apply gentle pressure and ensure it threads smoothly.
- Secure, Do Not Overtighten: Continue turning until the button is securely fastened. It should feel snug but avoid overtightening, as this can damage the threads on either the button or your camera.
- Verify Stability: Once installed, ensure the button is stable and does not wobble.
- Test Functionality: Lightly press the button to confirm that it activates the camera's shutter mechanism correctly.
Note on Compatibility: While designed for cameras with standard threaded shutter releases, including many Leica models, it is important to verify compatibility with your specific camera model. Some users have reported fitment issues with certain newer Leica M series cameras (e.g., M9, M240, M3, M9-P, M-E, M Monochrom) due to variations in thread depth or design. Always consult your camera's manual or manufacturer specifications for compatibility information regarding external shutter release accessories.
Operation
Once the Fotodiox Pro Soft Shutter Release Button is installed, it functions as an extension of your camera's native shutter release. Its operation is intuitive and mirrors the standard shutter button:
- Half-Press for Focus/Metering: For cameras with a two-stage shutter button, a gentle half-press on the soft shutter release button will activate the camera's autofocus system and exposure metering, just as the original button would.
- Full-Press for Shutter Release: To capture an image, continue to press the soft shutter release button down fully until the camera's shutter activates. The enlarged and smooth surface provides a more comfortable and stable point of contact, which can aid in smoother shutter activation and reduce the likelihood of camera shake during exposure.
The enhanced surface area allows for a more relaxed finger position, potentially leading to more consistent and sharper handheld shots.
Maintenance
Proper care and maintenance will ensure the longevity and optimal performance of your Fotodiox Pro Soft Shutter Release Button:
- Cleaning: To clean the button, gently wipe its surface with a soft, dry, lint-free cloth. Avoid using abrasive materials, harsh chemicals, or solvents, as these can damage the finish or material.
- Storage: When not attached to your camera, store the soft shutter release button in a clean, dry environment. Protect it from extreme temperatures, high humidity, and direct sunlight.
- Handling: Handle the button with care. Avoid dropping it or subjecting it to strong impacts, which could deform the threaded post or scratch the surface.
- Thread Inspection: Periodically inspect the threaded post for any signs of wear, damage, or debris. Ensure the threads are clean before attaching to your camera.
Troubleshooting
If you encounter issues with your Fotodiox Pro Soft Shutter Release Button, refer to the following common problems and their potential solutions:
- Issue: The button does not thread onto the camera's shutter release.
Solution 1: Verify camera compatibility. This button is designed for cameras with a standard threaded shutter release. Some camera models, particularly certain newer Leica M series cameras (e.g., M9, M240, M3, M9-P, M-E, M Monochrom), may have different thread specifications or designs that are incompatible. Consult your camera's manual for specific requirements.
Solution 2: Inspect threads for debris. Ensure that both the threads on the soft shutter release button and the camera's shutter release socket are clean and free of dust, dirt, or other obstructions. Use a soft brush or compressed air if necessary.
Solution 3: Do not force it. If the button does not thread on easily, it is likely incompatible. Forcing it can damage the threads on both the button and your camera.
- Issue: The button feels loose or falls off after installation.
Solution 1: Gently tighten the button. Ensure it is screwed on snugly, but avoid overtightening. Excessive force can strip threads.
Solution 2: Inspect threads for wear. If the button consistently loosens or falls off, the threads on either the button or the camera's socket may be worn or damaged. In such cases, replacement of the button or professional camera service may be required.
- Issue: The camera's shutter does not release after the button is installed.
Solution 1: Check installation depth. The button might be screwed in too far, preventing the internal shutter mechanism from depressing fully. Unscrew the button slightly (e.g., a quarter turn) and re-test the shutter function.
Solution 2: Verify compatibility. As mentioned, some cameras may have a different internal shutter mechanism depth that is not fully compatible with the length of the button's threaded post, even if it threads on. If adjusting the depth does not resolve the issue, the button may not be suitable for your specific camera model.
