How To Change Mount On Sigma Lens ?

To change the mount on a Sigma lens, you will need to send it to a Sigma authorized service center or a professional camera repair shop. The mount replacement process requires specialized tools and expertise to ensure proper alignment and functionality. Attempting to change the mount yourself can result in damage to the lens or camera body, and may void any warranty or service agreements. It is recommended to contact Sigma or a professional technician for assistance with changing the mount on your Sigma lens.

1、 Detaching the current mount from the Sigma lens

To change the mount on a Sigma lens, you will need to follow a few steps. Please note that this process may vary slightly depending on the specific lens model, so it's always a good idea to consult the lens manual or Sigma's website for any specific instructions.

1. Start by removing the lens from the camera body. Ensure that the lens is turned off and the camera is powered off before detaching it.

2. Locate the screws that hold the current mount in place. These screws are usually located on the backside of the lens near the mount. Use a small screwdriver that fits the screw heads and carefully unscrew them. Keep the screws in a safe place as you will need them later.

3. Once the screws are removed, gently pull the current mount away from the lens body. Be cautious not to apply excessive force or twist the mount, as this could damage the lens.

4. After detaching the mount, you will notice a metal ring that connects the mount to the lens. This ring is called the lens mount flange. Carefully unscrew the lens mount flange from the lens body using a suitable tool.

5. Once the lens mount flange is removed, you can now attach the new mount. Align the new mount with the lens body and screw it in place using the screws you removed earlier. Ensure that the screws are tightened securely but not overly tightened.

6. Finally, reattach the lens to your camera body and test it to ensure that the new mount is functioning properly.

It's worth mentioning that changing the mount on a Sigma lens is a delicate process that requires precision and care. If you are unsure or uncomfortable performing this task yourself, it is recommended to seek assistance from a professional camera technician or contact Sigma's customer support for guidance.

2、 Selecting the appropriate mount for replacement

To change the mount on a Sigma lens, you will need to follow a few steps.

1. Selecting the appropriate mount for replacement: The first step is to determine the mount type you want to replace. Sigma lenses are available in various mounts such as Canon EF, Nikon F, Sony E, and more. Make sure to choose the correct mount that is compatible with your camera body. It is essential to check the lens compatibility chart provided by Sigma or consult with a professional to ensure you select the right mount.

2. Gather the necessary tools: You will need a set of precision screwdrivers, lens spanner wrench, and a clean workspace. It is crucial to have the correct tools to avoid damaging the lens during the process.

3. Remove the old mount: Carefully unscrew the screws that hold the old mount in place using the precision screwdrivers. Once the screws are removed, gently detach the old mount from the lens body. Be cautious not to damage any internal components while doing this.

4. Attach the new mount: Take the new mount and align it with the lens body. Securely screw in the new mount using the precision screwdrivers. Ensure that the mount is tightly attached to avoid any wobbling or loose connections.

5. Test the lens: After replacing the mount, it is essential to test the lens on your camera body. Check if the lens is functioning correctly and if it is properly communicating with the camera.

It is worth noting that changing the mount on a Sigma lens can be a complex process and may require professional assistance. It is recommended to consult with a camera technician or contact Sigma customer support for guidance specific to your lens model.

3、 Aligning and attaching the new mount to the lens

To change the mount on a Sigma lens, you will need to follow a few steps. The process involves aligning and attaching the new mount to the lens. Here is a step-by-step guide on how to change the mount on a Sigma lens:

1. Start by removing the lens from the camera body. Make sure the lens is turned off and the camera is powered off before proceeding.

2. Locate the screws that hold the current mount in place. These screws are usually located around the base of the mount. Use a small screwdriver to carefully remove these screws. Keep them in a safe place as you will need them later.

3. Once the screws are removed, gently lift the old mount away from the lens. Be careful not to damage any internal components or the lens itself.

4. Take the new mount and align it with the lens. Ensure that the screw holes on the mount match up with the holes on the lens.

5. Once aligned, carefully insert the screws into the holes and tighten them using the screwdriver. Make sure not to overtighten the screws as this could damage the lens.

6. Once the new mount is securely attached, reattach the lens to the camera body. Ensure that it is properly locked into place.

It is important to note that changing the mount on a lens requires technical expertise and should be done by a professional or someone with experience in lens repair. Additionally, it is recommended to consult the manufacturer's instructions or seek guidance from a certified technician to ensure proper installation and avoid any damage to the lens.

4、 Ensuring a secure and tight connection between the mount and lens

To change the mount on a Sigma lens, follow these steps:

1. Remove the lens from the camera body: Start by detaching the lens from the camera body. To do this, press the lens release button on the camera body and twist the lens counterclockwise until it comes off.

2. Remove the existing mount: Once the lens is detached, locate the screws that hold the mount in place. Use a small screwdriver to carefully remove these screws. Keep them in a safe place as you will need them later.

3. Replace the mount: Take the new mount and align it with the lens. Make sure the mount is positioned correctly and then insert the screws back into their respective holes. Use the screwdriver to tighten the screws, ensuring a secure and tight connection between the mount and lens.

4. Test the lens: Once the new mount is securely attached, reattach the lens to the camera body. Twist it clockwise until it locks into place. Turn on the camera and test the lens to ensure it is functioning properly.

It is important to note that changing the mount on a lens should be done with caution and precision. If you are not confident in your ability to perform this task, it is recommended to seek assistance from a professional camera technician.

In recent years, Sigma has introduced a new line of lenses called the "Global Vision" series. These lenses feature a redesigned mount system that allows for easier and more secure attachment to camera bodies. The new mount design includes a locking mechanism that provides added stability and prevents accidental detachment. When changing the mount on a Sigma lens from the Global Vision series, it is important to follow the manufacturer's instructions to ensure proper installation and compatibility with your camera body.
