I bought the hideous Pentax Optio LS 1100 just before Xmas from Amazon. Quite happy with the camera until last w/e. I had the 'panoramic' setting to take some broad view shots. The camera switched itself off from standby. When i turned it back on again, the viewfinder is only showing everything in varying shades of green. If you take shots with it - they record in green too. Going through the menu, 'Green Button' is highlighted - but despite all attempts - it cannot be removed. Any ideas other than sending it back??
