I have recently purchased the Topaz Sharpen AI in March 2020 and is very surprised on how effective it is. Let the images speak by themselves. You can notice that with the power of AI, the digital stabilization is even better than the optical image stabilization (OIS) by the lens! After the test, I can say that the "stabilize" function of Topaz Sharpen AI can offer about 4-5 stops for a 200mm lens without OIS.
