Supports manual control, manual focus, manual exposure, and focus to infinity. 【First Use】Activate your camera setting as "Release without lens" when first using a manual adapter, as the camera will not recognize your lens otherwise and cannot take pictures. Please note: Infinity focus position: The position of the infinity mark 【∞】 of the telephoto lens or super telephoto lens is slightly shifted to the positive side to allow for focus adjustment, even if focus shift is caused by temperature changes. The shifting range is marked by an L-shaped line. Be sure to check focus through the viewfinder even when shooting at infinity."
