Hi Brian,
I went back to my deleted files and took another look at your tree in
Photoshop.  It may have been an overcast day, but it still looks like a
nice soft blue sky to me in the back ground.  So it was still a pretty
bright day.
After re-reading your post it looks like you may have shot the tree with
the 35-70 f3.6 and possibly without a hood.
Where you standing in the shade of the trees or where you out in the
open under the overcast bright sky?
I do not believe you have to have direct sunlight to cause flare.  A big
white cloudy sky can still produce it.

In my way of thinking, if I've got flare in my photos, then I think I
did not take the correct measures to prevent it.  I don't worry about,
does this lens have too many elements and all that stuff.  Some of my
favorite lenses for landscape photos are the 35-70 f3.6 and 85-250 f5.
But, I ALWAYS make sure my front lens element is shaded.

If you want to reduce the contrast on the big tree photos I would try a
very early morning outing.  My favorite time to shoot is the first 2
hours or so of sunrise.  I can always tell when it's time to quit.  The
light just does not feel right anymore and I pack up and leave, sort of
a sad time.

Anyway, I would not loose confidence in your 2 lenses until you do a lot
more testing.

Good luck and have fun.
Buddy Walters

Hi Buddy

For the photo on my website, the day was quite overcast. I needed
overcast 
to reduce the contrast. That tree casts SO much shade it is difficult to

imagine. The sun would have been coming over my left shoulder, yet the
flare 
is on the right. (Looks at notebook) I don't think I had the hood for
that lens 
at that stage (got one later courtesy Bill Barber - thanks Bill). But it
was a 
tripod shot and I put my hand on the camera to steady it even more. In
my 
opinion the flare comes entirely from the bright light reflected from
the white 
trunks of the Eucalypt trees shining through the gaps in the macrocarpa 
branches and foliage. And it has affected the darkness of the image of
those 
darker branches and trunk 

For the 75-150, I'm 90ure I would have used the hood. After all, it's
right 
there with that lens.
