Tony,
Sorry for taking so long to get back to you. Being new to this forum, I did not realise you could get personal messages. The email is not my work one so I dont look at it that often.
My problem is that some images seemed washed out and out of focus. Here is an example taken at F8. The lighting conditions dont seem overely complex to me so I would expect a reasonably sharp shot.
