Please refer to product description.
Advanced lens adapter with built in aperture diaphragm (blades)
Stepless aperture control ring with f-stop reference markings from F2.8 to F22*
There is no electronic connection so the lens must be controlled manually
Focus to Infinity.
It is possible to use Macro rings and other accessories.
Material: Chromed Brass and Anodized Aluminium
This adapter is compatible with Canon EF Mount lenses
*This adapter is not compatible with Canon EF-S lenses
*Please note that for some lenses the vignetting will grow as you narrow the aperture. This will be more obvious in a smaller aperture lens or a longer lens.
*Also note that the f-stop markings on the aperture ring are for reference only. F2.8 simply means wide open and F22 fully stopped down. The actual f-stop will depend on the aperture range of the lens used. For example, if you have a lens with an f-stop range of F1.8 to F16, this will still be the aperture range of your lens using this adapter and F2.8 on the adapter will be F1.8 with this lens.
This is a physical lens adapter only. All electronic lens control functions through your camera will not work, including electronic aperture control and auto-focus, and you will be required to operate all lens functions manually. If the lens you use with this adapter does not have an aperture control ring you will need to use the built-in aperture control on the adapter as you will not be able to adjust the aperture of your lens in-camera.
