Warranty Limited 24-Months • This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. • 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus. • Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. • All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.
