Mount replacement for the lens?

Just some clarification, it's just the lens mount itself that's bent (the part in the image below)?

Is it just one of the locking tabs on it that's bent? I just want to make sure that it is only the lens mount that's damaged and not potentially that the part connected to it might be damaged as well. If you add an image to your post, it could be helpful with that.

Notes About Replacing the Lens Mount:

Replacing the lens mount is definitely possible, but it's not quite as simple as swapping it out for a new one. The reason why is the thickness of the lens mount varies slightly between each individual lens. At the factory, the lens undergoes focus adjustments which involves changing the thickness of the lens mount (to change the distance between the lens and the camera) until it's in perfect focus.

At the factory, they just use a thicker lens mount and shave the lens mount down until they achieve the needed thickness. However to make replacement possible in the field, there are pre-sized lens mounts with different sized plastic washers you can get. You'll need to find the combination of which lens mount and washers you need to match the thickness of your current lens mount.

This image above is from the service manual and the two charts shows you the available lens mounts and washers. You can see the lens mounts range in thickness from 1.9 - 2.7mm.

How to Know Which Lens Mount You Need:

1. Remove the lens mount from the lens. The first couple of steps on this guide will show you have to remove it.
2. Measure the thickness of your lens mount. The measurement should be taken of the outer ring of the lens mount. Fig.2 in the image above shows where to measure, but since it's hard to interpret I also took a picture of a similar lens mount and marked where you need to measure (image below).
3. Pick the lens mount that you need from the ones available in Fig.2 above. You will want to round down, so if you measured 2.37mm, go with the 2.3mm lens mount.
4. Determine the combination of washers (which come in 0.02 and 0.05mm thicknesses) to get the total thickness to match that of the original lens mount. For example, if you measured 2.37mm you'd get a 2.3mm lens mount and a 0.2mm and 0.5mm washer to get the total thickness to the 2.37mm. You might not be able to get the thickness to perfectly match, but just get them as close as you can get it. Also note, the combined thickness of the washers cannot exceed 0.07mm.

How to Find Replacement Lens Mount:

You can find a number of websites selling both the lens mount and the washers. You'll have to search for them by their part numbers.

• Lens Mount Part Number: CY1-2180-###
  • The ### should be replaced with the size number which corresponds to the thickness of the lens mount which can be seen in Fig.2 above.
  • For example, the size number for a 2.4mm lens mount is 240, and therefore the full part number would be CY1-2180-240
• Washer Part Number:
  • 0.02mm washer: CY1-2178-002
  • 0.05mm washer: CY1-2178-005

When installing the new lens mount, install the washers underneath the lens mount.
