Canon 100-200mm f/5.6 Manual Focus Breech Lock Lens for FL-Mount (AS-IS)

Canon FL 100-200mm f/5.6 Lens (Breech Lock)
Vintage Manual Focus Telephoto Zoom – SOLD AS-IS / INTERNAL FRONT FUNGUS
The Canon FL 100-200mm f/5.6 is a classic, beautifully crafted vintage manual-focus telephoto zoom lens featuring Canon’s traditional chrome breech-lock mount. Introduced during the peak of the analog film era for the FL lens ecosystem, this lens offers a highly practical 2x telephoto zoom range that is ideal for isolating distant landscapes, capturing outdoor portraits, and experiencing vintage compression. Clad in a heavy-duty, all-metal barrel with etched focal scales, it provides a completely mechanical, tactile shooting experience.

Please note: This vintage lens is being sold strictly AS-IS due to a ring of yellow fungus inside the front element. It includes a rear lens cap and is priced heavily discounted for restoration projects, lens repair practice, or creative lo-fi photography.

Key Features & Vintage Attributes
Practical Telephoto Zoom Reach: Covers a versatile 100-200mm range, allowing photographers to easily pull in distant details or create flattering compressed portraits with great subject-to-background separation.

Classic FL Breech-Lock Mount: Features Canon’s iconic metal breech-lock ring interface. It is natively compatible with vintage Canon FL-mount and FD-mount manual film SLRs (such as the Canon FT, FTb, and AE-1) or can be easily adapted to modern mirrorless digital camera bodies.

All-Metal Mechanical Craftsmanship: Built with the uncompromising structural durability of the FL era, featuring a fully mechanical zoom and focus ring layout that contains no delicate modern electronics.

Constant Physical Length: Designed with an internal mechanism that maintains the structural length of the lens barrel while zooming, ensuring balanced handling on your camera body.

Item Condition & AS-IS Diagnostic Notes
Optical State (Front Fungus): SOLD AS-IS. There is visible yellow fungus growing around the inside of the front element. This organic contamination will reduce overall contrast, soften fine details, and can cause light scattering or a hazy flare when shooting toward bright light sources. This lens is an excellent candidate for an optical teardown/cleaning project, or for shooters looking to achieve a distinct, low-contrast vintage dream aesthetic.

Mechanical Status: The core mechanical mechanisms are fully functional. The focus ring rotates through its throw, the push-pull/rotational zoom mechanism operates, and the manual aperture ring sets accurately.

Included Accessories: Comes equipped with a compatible Canon breech-lock rear lens cap. (Front lens cap and lens hood are NOT included).
