Simple unboxing,video today, no review.
This lens converter will effectively double the focal length of the lens to which it applied and double the magnification.
To use, align the red dots on the lens and converter then twist clockwise until you hear it engage. Then fit the lens/converter to the camera body by again aligning the red dots but this time twist couter clockwise to lock.
Take note that this converter will work with all Canon EF lenses and maintains the autofocus feature. It will not work with lenses below 60mm focal length and best results are obtained with prime lenses 100mm or above. It will not work with Canon EF-S lenses or the 70-300mm f/4-5.6 IS USM and EF 24-105mm f/4L IS USM Lenses.
