slowest I can shoot at 70mm is around 30. 

I way overpaid for my copy; went on a business trip to NYC and decided to visit the epic BHphoto store.  I got absolutely caught up and purchased one there.  aside from my tse17, it's the sharpest lens I have.  Can't believe it's a zoom.

The 1/FL 'rule' should be 1/2xFL or more for today's higher resolution digital sensors (and higher still for crop sensors).

Personally, I use a minimum shutter speed setting of 1/125 s.

+1. There is a setting on 5DIII to restrict speeds slower than a set point (with auto ISO).

Thanks for the tip.  I mostly shoot in full manual, but I typically have Custom 1 set for grab shots with auto ISO.

To guarantee 9 times out if 10 no relevant shake I'd have to be around 1/140 or twice the focal length. I'd get some OK at 1/70, maybe 50%

The earlier advice to 'double tap' is good and does work. Inevitably it's the second frame that is sharper, I have no idea why.
