No, this is a manual adapter. Autofocus is not supported. You will need to manually focus your Pentax K lens.

Yes, you can control the aperture using the aperture ring on your Pentax K lens. Ensure your camera is set to a mode that allows for manual aperture control, such as Aperture Priority or Manual mode.

No, there is no electronic communication. All functions, including focus and exposure, must be adjusted manually.

It is designed for Pentax K mount lenses. However, due to its manual nature, it's best suited for lenses with manual aperture rings. Lenses that rely entirely on electronic control for aperture may not function as expected.

This adapter is designed for Canon RF mount cameras, such as the Canon EOS R, R3, R5, R6, R7, R10, R50, R8, R100, etc.

Gently wipe the metal surfaces with a clean, dry microfiber cloth. Avoid using liquids or abrasive cleaners.

Ensure there are no obstructions on the camera mount or adapter mount. Verify you are aligning the correct indicator marks and rotating firmly until it clicks.

Check the lens mount and adapter mount for debris. Ensure the lens is properly aligned with the adapter's mount before rotating to lock.

This adapter requires manual exposure. Ensure you are adjusting the camera's shutter speed and ISO, and the lens's aperture accordingly. Set your camera to manual mode (M) for full control.

Confirm the lens is properly seated on the adapter and the adapter on the camera. Use your camera's live view zoomed in to achieve critical focus using the lens's focus ring. Some adapters may have slight variations in flange distance; recalibrate focus using the adapter.
