A well-known guideline for hand-held photography is that in order to avoid
camera shake, you should not use a shutter speed slower than one over the
focal-length of the lens. So, for a 100mm lens, don't go slower than 1/100.
Since that's not a standard speed, round up, and don't shoot slower than
1/125.
Here's the question: What's the equivalent rule for the E-1? (Or more
generally, for any system with a frame size different from 35mm).
My feeling is that you need to convert to the 35mm equivalent in order for
the rule to still work. That is, if you get camera shake when shooting a
100mm Zuiko at 1/60, then you'd also get shake when shooting the 50mm
Digital Zuiko at 1/60.
That's right, isn't it?
