Fake Double Exposures IN CAMERA with Canon

Canon does not have a setting to allow in camera double exposures like the Nikon.  Tony Sweet's Blog wrote about a work around for Canon that I found interesting.  He uses a single long exposure, such as 2.5 second.. During the exposure he zooms in for a fraction of a second several times along the way for the duration of the exposure. 

I tried this - but not very happy with the results.  See what you think, but I prefer Nikon and the real deal!!
