Nothing really is spectacular it seems.  The MZ 7-14/2.8 is good enough accept 
at 7mm.  If doing astro, AF is a blessing as starry sky AF is so consistently 
good.

The PL 9/1.7 is quite small and not bad.  If one looks at the raw files with a 
converter that doesn't process the imbedded corrections, it has a ton of barrel 
distortion!  
There are very few astro images with it to be found so not sure how the 
converters correct the distortion and whether they stretch the stars in corners 
or not. 
I've never seen a coma analysis using a converter that doesn't do the 
corrections.

It looks better than the MZ zoom at 7mm but that is the weakest focal length 
for distortion with that lens. 

OM systems needs to get off their duff and optimize a UWA prime for such use 
since the cams are so durn easy to use for this application.


No wings on my stars please, Mike
