Canon EF to EF-S conversion for 7D

If you search long enough or troll photographic forums you will find people talking about  “crop factor” and what it is etc.. but usually they only give one example.  I decided to go to B&H photo’s website and grab every lens from 7mm to 18mm on the small end made for an EOS body and do the maths to show what the equivalent EF-S lens view would be using my 7D and its 1.6 crop factor. I extrapolated from 7mm and stopped at the 18-55mm EF lens to show you how different it could be. See below graphic. I will eventually add more to this post.
