I've only posted this photo because of the obvious flare/flaw. I'm sure I should know the reason for it but I don't:

What's likely to have caused this, and how could it be reduced/avoided?

It's caused by lens flare. Simple explanation here: -

In reply to MJ: Hi thanks for the reference. Looks like I need a lens hood then - I bought one from Jessops the day before they went belly up, unfortunately their own brand caused vignetting.

Easily prevented by using your hand as a sunshade and casting a shadow over the lens,

Nah, let him get a lens hood, they make lenses look so much better! :p

In reply to Rob Exile Ward: Simple laws of Physics. More glass means more reflections within the lens. As most modern zooms have 12/16 glass elements within their construction and filters on the front,then flare is often unavoidable when shooting directly into the sun.

Probably more down to a wide angle lens than the actual hood. As Chris says, use your hand or something like a map to shield the lens.

And how will that save your lens when it stots off the rock? 1st year using a camera on the crag.
