[MF & Infinity Focus] When using this product, there are no electronic contacts, so focusing is MF (manual focus), and aperture adjustment is also entirely manual. Infinity focus is achievable. Other functions will not work properly while using this adapter ring. (Please turn off the camera's power when attaching the adapter.)

[High Quality & Portability] Made of high-quality copper and aluminum alloy, it will not damage the lens body. Durability has also been greatly improved. It is lightweight and compact, making it highly portable.

[Easy Operation] Marked with a red indicator, you can accurately adjust the aperture by aligning the indicators on the camera and lens and rotating. Attaching and detaching the lens is easy.

*The adapter has an aperture ring, allowing aperture adjustment on the adapter while it is attached.
