Canon EF 50mm F1.4 Disassembly Procedure

[fatigue]

Another step by step procedure.

Remove the screw holding the contact pins


Remove the 4 screws on the metal mount


The metal mount could not be removed totally
Must remove the black plastic cover first.


It is attached only by clip, be careful not to damage these 4 plastic clips

[fatigue]

Remove the FPC connected to the PCB


Remove the screw holding the PCB, then remove the PCB (handle carefully to avoid ESD)


Remove the 3 screws in front of the barrel


Then you can remove the front ring and focusing ring


Remove the metal switch for distance encoder

Cool? why 50 f1.4? Why not a 50 f1.2L? Even cooler. See how to remove red band and change to orange or purple band-canon new limited addition series?

I thought these things must be done in controlled environment to prevent dust? What they call clean room is it?

A bit OT:

Does service centers clean their lenses inside a cleanroom?
Or is there any shop that performs cleaning inside a cleanroom?

There are ways to avoid forgetting the sequence: you can separate each screws, you can use my post, you can take photos of each step and so on...
Last option: contact 98151974, just don't loose any parts

you don't need to dismantle a lens just to hide/change the red ring.
Use gaffer tape or other colored tape
May I ask, why would somebody hide the red ring when it's obvious that you're using an L lens? In fact, I know some guys who puts a red tape on their ordanary lens to make it look like an "L"

try searching for the word "cleanroom" in this forum

[fatigue]

Back to topic:

Remove the 3 screws (around the front barrel) holding the white spacers


Now you can remove the inner part

[fatigue]

Exceeded maximum photos uploaded per day

The lens got fungus. Need to access the inner parts to clean

Why post?
1. Passing basic knowledge for DIY wannabes
2. I'm just like other photographers here. Some shoot models, some shoot insects, some shoot landscape and so on. Me, I shoot what's inside the lens.

There are a lot of good photographers here that if I post my ordinary shots, nobody will pay attention. With this kind of post, some DIY wannabes will pay attention
