Re: Another test of DA 16-45/4 against other Pentax glass

[Herb Chong]

from what is posted, i can't see anything that i can safely conclude is 
chromatic aberration. i don't expect any of the posted images to really show 
significant CA anyway since the contrast isn't too high. of Jostein's test 
lenses, i have the DA 16-45, the FA* 28-70, and the 31 Limited. i have some 
brick walls i can shoot too, although they won't be rectangular bricks. it's 
heavy overcast and a bit windy, but i think i can get some shots.

Hmmm, even with  my reading glasses on I don't see anything that I would 
call fringing on most of the shots. I see some minor difference in color 
rendering. The only place I see something that I would call fringing is on 
the FA 20/2.8 at f22 and f8. It's somewhat evident on the upper branches 
of the pine tree. Perhaps these crops display differently  on different 
monitors. I'm looking at them on a 21" Apple Cinema Display. Perhaps a 
high end CRT might reveal more or perhaps some CA is monitor induced. I'll 
be interested to hear what Rob and Herb see.
