4. Delovanje
4.1 Autofocus and Image Stabilization
The adapter fully supports the autofocus and image stabilization features of your Canon EF/EF-S lenses when used with compatible Canon EOS R series cameras. No additional settings are required for these functions to operate.
4.2 Using Drop-in Filters
- Circular Polarizer (CPL) Filter: Rotate the outer ring of the CPL filter to adjust the polarization effect, reducing reflections and enhancing color saturation.
- Variable ND (ND3-ND500) Filter: Rotate the outer ring of the VND filter to adjust the light density from ND3 to ND500 (equivalent to 1.5 to 9 f-stops), allowing for slower shutter speeds or wider apertures in bright conditions.
- Clear Filter: Use the clear filter when no other filter effect is desired, to protect the camera sensor from dust and maintain optical integrity.
