Panny
+ smaller - 1/6th stop faster, lighter, cheaper, slightly sharper 1.7-2.8.
- Slower, noisier AF (audible in quiet movies), 0.4 stops more vignetting (meaning it is slower in practical usage except at the centre), more CA, focus by wire only, cheaper made.

Oly
+ Slightly sharper f4 to f11, Mechanical and electronic focus, proper lens hood available, less vignetting, less CA, quieter focus (I've never heard a peep out of it), better made.
- more costly, larger (but not large), marginally less sharp edges wide open.

They are both good lenses and BOTH trounce the Zuiko 17/2.8 except on price.  It is plainly a 'swings and roundabouts' situation.

So .. I struggled with this for a while - ended up going for the Zuiko and am very happy.  Isn't choice grand?
