YONGNUO YN2.0X III 2x Teleconverter Extender Auto Focus Mount Lens Camera Lens for Canon EOS EF Lens
The optical design and glass coating have raised the level of the teleconverter. In addition, the redesign of the upgraded electronic aspect makes the auto-focusing function of the teleconverter able to adapt to more lenses, such as the EF70-200MM F/2.8 L IS II, the EF70-200MM F/2.8 L IS II USM and most of the lens can achieve automatic focusing.
Using an Extender with this lens may result in incorrect autofocus. If your camera has an AF micro-adjustment function, do the AF micro-adjustment. If your camera does not have an AF micro-adjustment function, focus manually if the AF precision is way off. If the automatic focusing does not smooth, it is because the lens aperture is too small, and zoom out two stops of the aperture to decrease half of the light. At that time please use the automatic focus. Mounting and dismounting the Extender First attach the Extender to the lens, then attach it to the camera. Please follow the opposite procedures to disassemble. To detach the Extender from the lens, push the lens release lever as shown by the arrow, then turn the Extender counterclockwise.
