The macro photography was something that I always wanted to try. So, I hopped on Amazon and started searching for a reverse lens for my lens. But, to my surprise, I ran across this device that will also allow you to use your lens with autofocus. This device is manufactured by a company called MovoPhoto, and the model number of this device is ext-c5 v2. So far, the autofocus is sort of a pain in the butt to get working, but I use manual mode for now. I will be adding more images as I have the time to capture them.
