Dear all,
First thanks all who response my question.
I am sorry that I only get *"digest" *so I cannot reply article by article.
I'm glad that someone who point out my question. Maybe I mistake about
chromatic aberration as Winsor said & thank you very much for Winsor's
explanation.
I took the picture with Fuji Superia 100 film & scanned by Nikon CoolScan IV
ED. I wondered there is "purple fringing" around the roof at the edge of
highlight area. I can find it even for my Zuiko 24mm F2 ~_~

Why I think there is chromatic aberration for the Tamron SP 17mm F3.5 since
I cannot find same stitution for my Zuiko 90mm F2 Marco ................

Unfortunately, my English is poor, I still cannot distinguish CA & digital
bloom ................
Anyway, thanks all to let me know what is "chromatic aberration" ^^
Btw, I image another problem ................. there is no optical photo
printing in HK & all changed to digital photo printing ............. means
the photo will be scanned before printing ............. As Winsor said, how
do I avoid the "purple fringing" for the photo?
Michael
