Mechanical design without electronic contacts: aperture and focusing are manual.
Precise fit: rigid metal construction ensures secure mounting of lens and camera.
Maintains flange focal distance: correct focusing at all distances, including infinity ∞.
Compact and lightweight: does not add significant weight to the system.
No impact on image quality: optically neutral (no lenses or filters).
Manual focus and aperture: the adapter does not transmit EXIF data and does not control autofocus or electronic aperture.
No stabilization: if the lens or camera has built-in stabilization, it may not work or may work with limitations.
Compatibility check: some large PL lenses may cause vignetting on Sony full-frame cameras.
Infinity focus: guaranteed for correctly calibrated PL lenses.
