No not daft at all, it made Friday morning more interesting. I do enjoy a bit of camera geekery.
On a completely separate tangent, I really like the photograph of The Roaches. I don't think I've seen this view before. Makes me feel a little restless, as I feel quite landlocked in London. I never go anywhere else with my camera, and I'm starting to get a hankering for photographing somewhere different for a change. :)
