⚡ At a Glance
- • Image Quality: Direct mechanical coupling preserves original lens rendering and focusing behaviour without electronic interference
- • Best for: Enthusiasts adapting M42 screw lenses to Canon FD bodies who prefer full manual control
- • Not ideal for: Photographers who require autofocus or automatic aperture control from the camera body
Mechanical M42-to-FD coupling supports infinite focus and requires manual diaphragm control. Alloy and plastic construction keeps weight low at approximately 30g and provides a sturdy mount for regular use.
Precise manual focusing - Thanks to the mechanical M42-to-FD mount
Mechanical mount connects the M42 lens helicoid directly to the FD mount without any ROM communication, allowing continuous, infinite focus. Electronic autofocus and automatic diaphragm functions are not present because there is no electronic interface.
Accurate, tactile focus control suits close-up work and deliberate shooting with vintage glass, delivering predictable focus behaviour for careful framing.
Reliable build for field use - With alloy construction and smooth finish
Stable alloy body combined with plastic components creates a solid interface designed to resist wear and maintain mount alignment. Smooth surface and tight tolerances simplify fitting and removal.
Durable construction reduces risk of looseness or misalignment over time, making the adapter suitable for repeated on-location use.
Lightweight portability - Thanks to approximately 30g construction
Compact design and light materials lower the overall weight added to a camera and lens setup, measured at roughly 30 grams. Minimal bulk reduces strain during long shoots or when travelling.
Easy to carry in a camera bag without noticeable weight, convenient for photographers who move between locations frequently.
