Using PL-mount lenses with long base on Canon EOS cameras via adapters
13 years old. Gear and prices may have changed since.
What the thread found
- PL to EOS adapters designed for long base PL lenses are available but may not achieve proper focus with prime lenses on full-frame cameras.
- When using PL adapters on EOS cameras, long base PL prime lenses can function only as macro lenses with extended working distances rather than at their normal focal lengths.
- PL to EOS adapters work reliably with zoom lenses across various focal lengths.
- Removing the camera's mirror through specialized modification services enables the use of long base PL lenses on full-frame EOS bodies by providing additional depth for the lens mount.
Depends on
- Testing was limited to specific lens models (Zeiss Superspeeds, not CP.1) and one camera body (Canon 5D).
- Focus accuracy issues were encountered but may not apply universally to all prime lens designs or camera models.
- Mirror removal requires professional modification and is not a standard mounting solution.
- The effectiveness of long base PL adapters varies by specific adapter design and lens characteristics.
