Can you use Canon FD (manual focus) lenses on the GoPro ILS?
Yes, Canon FD lenses are probably one of the best options for adapted vintage lenses (for VIDEO) because the adapters provide stepless aperture control. The image they produce looks kind of vintage though, which some like (and some don't).
Advantages of Canon FD Lenses for Video
Stepless Aperture Control: The adapters for Canon FD lenses allow for smooth, continuous aperture adjustments, which is ideal for video work.
Vintage Aesthetic: The image quality often has a unique vintage character, which can add a distinct look to video projects.
Build Quality: Canon FD lenses are well-constructed, often featuring metal bodies and high-quality glass.
Affordability: Compared to other vintage lenses, Canon FD lenses are generally more affordable, making them accessible for filmmakers on a budget.
Considerations
Image Quality: While many appreciate the vintage look, it may not be suitable for all projects, depending on the desired aesthetic.
Compatibility: Ensure you have the right adapter for your camera system to utilize Canon FD lenses effectively.
Focus Mechanism: Manual focusing can be challenging, especially in dynamic shooting situations.
