I caught the 'shadow bands' in 4 consecutive images although nowhere near as clearly as you. Check the second image here:

Funnily enough, my sequence of shots through the first Diamond Ring in the 2010 eclipse were almost duplicates of 2012 as the Sun emerged from thin cloud, but there isn't really any sign of similar banding. 
The only difference this time was that due to a dreadful clerical error I was shooting at ISO 1600 eek, must have forgotten to wind it back in the heat of the moment!  Obviously there are many factors at work - if the bands are projected onto the cloud layer from upper atmosphere effects then ideally the cloud layer should be quite thin and uniform to transmit the bands. Maybe the clouds I imaged through in 2010 were 'fluffier'?? FWIW comparison images are attached.
Congrats again, amazing stuff!

Thanks very much Rob, and well done on capturing the shadow bands as well! Also congrats for the "Optics image of the day"!
It is an interesting difference between 2010 and 2012 - perhaps due to differences in the atmospheric turbulence as well as the cloud thickness? I'm looking forward to the next eclipse to see if they are visible again!
Cheers,
Stephen
