Curious---I am glad it works well as it is  a very small kit indeed.  
Calculation of the  "effective Mag" doesn't seem as straight forward as 
Usually M=FL prime or zoom/FL diopter which at 12mm for the zoom in 
exif doesn't amount to much---.03 X.  though mag not really changed by 
cropped sensor it is effectively
increased by  .06 X by the diopter, though have never seen these 
calculations for cropped sensors.  I think the lens itself goes to .13X 
or effectively .26X and perhaps with the diopter final display is 
closer to
0.4 X though that is a quick estimation.

Must wait for Dr. Butter  to clarify, Mike
