Why Disassemble the Auto Toyo Optics 28mm FD Lens?

Before jumping into the disassembly process, it’s worth asking—why take apart your lens in the first place? Some common reasons include:

Cleaning dust or fungus: Older lenses are prone to internal dust and fungus buildup.
Repairing stuck focus or aperture: A vintage lens may need some TLC to restore smooth operation.
Curiosity or customization: You might simply want to understand how it works or modify it.

Tools You’ll Need

Before you begin, gather the necessary tools. Having the right equipment makes all the difference:

Small Phillips-head screwdriver
Lens spanner or precision tweezers
Microfiber cloth (for cleaning)
Blower bulb (to remove dust)
Magnifying glass (optional but helpful)
Small containers (to store screws and tiny parts)

Pro tip: Always work in a clean, well-lit area to avoid losing small components.

Step-by-Step Guide to Disassembling the Auto Toyo Optics 28mm FD Lens

1. Inspect the Lens

Before you touch any screws, take a good look at your lens. Familiarize yourself with its parts, including the aperture ring, focus ring, and mounting flange.

2. Remove the Front Ring

Use a lens spanner or a rubber tool to gently unscrew the front nameplate (where the “Auto Toyo Optics 28mm FD” branding is).
Be careful not to scratch the surface—gentle pressure is key.

3. Detach the Front Element

Once the nameplate is off, you’ll see the front glass element. Carefully unscrew it with your hands or a spanner tool.
Place the glass element in a safe location.

4. Disassemble the Aperture Assembly

Locate the screws around the aperture ring. These hold the assembly in place.
Unscrew them and lift the aperture assembly out. Pay close attention to the alignment of the aperture blades—take a picture if needed for reference.

5. Focus Ring and Helicoid

The focus ring is connected to a helicoid mechanism that allows the lens to focus.
Unscrew the focus ring carefully, noting its position relative to the lens body.
Once removed, clean the helicoid threads and reapply grease if necessary.

6. Access the Rear Element

Flip the lens over and locate the screws on the rear mounting flange.
Unscrew these to release the rear element.
Like the front glass, store it safely.

7. Clean and Inspect Components

Now that the lens is disassembled, inspect each part for dust, fungus, or wear. Use a blower bulb to remove dust and a microfiber cloth for cleaning glass surfaces.

Reassembling the Lens

Reassembling the lens is essentially the reverse of disassembly. A few tips to make this easier:

Work slowly and patiently.
Refer to your photos if you’re unsure about the alignment of parts.
Test the focus and aperture mechanisms as you reassemble each section.

Important Tips and Warnings

Be gentle: Lens parts are delicate, and force can cause irreversible damage.
Avoid touching the glass elements: Fingerprints can be a pain to clean later.
Stay organized: Use small containers to keep screws and components safe.
