Dear David and fellow Zuiks --
I think this is a case of Ultraviolet sensitivity of color film and
I would guess that you did not use any type of UV absorbing filter
over the Zuiko 180 mm lens.
Ultraviolet can cause just the sort of effects that that you showed with
those nice images of the brunette in the white top and khaki skirt.
I don't think this is a case of chromatic abberation -- the focus of different
wavelengths at different plane.
Single coated lenses transmit more ultraviolet light than multicoated lenses.
Most of the time ultraviolet does not cause a problem but on bright sunny days
or other bright illumiation ultraviolet effects show up.
If you can find a Wratten 1A or 2C filter gel and a holder for your lens
then you'll have a good solution. Filter gels are thinner and optically better
than glass filters, so you'll probably be happier with the results if you can
find a suitable gel
holder. I use both an old Kodak metal holder and a Cokin filter holder with
a 3X3 gel holder on my 49 and 55 mm Zuikos but I don't know if this will work
for the big 180mm -- what is the filter size ?
For ultraviolet photography, of course gels won't work so I use a B&W glass
filter containing Schott UG1 glass. http://flzhgn.home.mindspring.com/uv.htm
When I want to remove all UV light I use a Wratten 12 yellow filter.
Now I want to know more about the Vivitar 17mm lens because I just bought one !
I am thinking of getting a UV0 glass filter for protecting the front element
maybe I should
consider a Wratten 2C or even a 2E !
I think Kodak films are generally less sensitive to ultraviolet effects than
Fuji films
except for Kodak EIR and Fujichrome 64 T which are both wonderful for
photographing
true ultraviolet images.

> Velvia, Provia, Astia are professional-use films with colored film

>
> Color reappearance:
> Trebi True color
> Sensia Settled kind
> Velvia Higher saturation than actual color
> Provia True color
> Astia True color, beautiful human skin

> Gradation:
> Trebi Standard
> Sensia Soft
> Velvia Vivid
> Provia Standard
> Astia Soft
>
> Recommended for:
> Trebi All purposes, good for beginners and those not used to

> Sensia All purposes incl. medical and scientific usages.
> Velvia Those who want sharp and powerful details, brilliant colors,
> excellent quality or high resolution.
> Provia All purposes. Select this if you are wavering in choice.
> Most commonly used.
> Astia Especially good for female and baby shots. Select this when
