EX1 shock resitent ?

The camera is most vulnerable when the lens is in it's out position or if the amoled screen is swivelled out.

Since it was in a bag, I doubt either of those situations existed. The bag would've absorbed some of the shock - varying from negligible in a paper bag to pretty good in a padded camera bag - not sure of the padding in the exterior pockets though.

It is not shock proof but there is a very good chance with this fall, you'll be ok.
