Hi Brian,
I'm sure you have thought of this, but since no one has mentioned it.
I would first make sure your hood was fully extended on the 75-150mm.
If it was, I would make sure on your next test to shade the lens front
with a hat or hand.
I watched a professional photographer, who I am pretty sure was John
Shaw (with his new beard) in Denali Park shade every shot he took.
Just a little food for thought.

Subject: [OM] ( OM ) Internal lens flare
A question for Zuiko users,
I have begun to notice what I think is internal lens flare in a couple
of my
Zuiko zooms. The SC 75-150 f/4 (my USD25 fang!), shown in several
prints
I picked up yesterday, and the 35-70 f/3.6. I have one example on-line
at
http://homepages.caverock.net.nz/~bj/photography/zuikoholics/cup-mac.htm
There is marked lightening of bark colour on the RHS where the dark tree
branches border an area of bright diffuse light.
But I won't display the other just yet as it may end up being part of
the
current TOPE show; however the general situation is the same; dark
abruptly
moving to bright light. The effect is just like the loss of contrast and
general
fogging that results from fungus in a lens - but I'm sure these two are
OK in
that regard. Or were last time I looked.
Have any of you seen this phenomenon also?
I will probably test both subjects with other lenses of which I suspect
no
such problem.
Brian
