Good point but that's 90 degrees to the rollers, however I was out shooting 2 days ago and came across a similar lighting condition for a short spell, and shooting into the light was impossible.
In the shot in question the shadows are soft yet the top centre of the image is heavily burnt out, but it's not like bright sunlight it's more a wall of light.
What I found while shooting on Thursday, a bright mostly sunny day was some slight cloud suddenly took the blue sky reading from from Zone VI to about zone XI/XII, that's before taking into account the actual lighting on the subject had dropped. I suddenly had that wall of light behind what I was photographing. When the cloud passed I could shoot again despite the bright direct sunlight only just being out of the frame.
It's harder to describe than the reality.

Ian, I understand what you're saying. But the OP's images don't appear to have a similar problem. It REALLY looks like a steamed lens to me.

Mike, believe me the OP's image shows the EXACT problem I'm describing and had to dodge out on the example I posted.
If the lens was steamed up then it's rather a coincidence it just happens to match the heavily overexposed area of sky :)

I'm not always right, Ian, but often am. We'll see... :D

just a quick update - I'm waiting for my latest batch of film to come back from the lab so I'll have a bit better idea when it does, especially as I've made some notes on weather, temperature, direction of light etc.
One question that did spring to mind this morning was: Is it possible to damage the lens coating by shooting into strong light/ sunlight?

No of course not, coatings are quite robust, physical wear and tear yes, sunlight no.

I've seen this as well with my C330s & 80mm. Using the lens shade eliminated the problem.

Tony this image (http://www.apug.org/gallery1/showimage.php?i=50254&catid=newimages) posted by Cheryl Jacobs illustrates clearly your exact problem, in her case the Bronica 75mm lens is Multicoated.

The earlier lenses for the Mamiya C cameras especially the silver ones were only single coated and quite prone to flare, most of the later black ones were multi-coated.
