I have the above camera but no lens hood. It seem that the Pentax hood for it is the RH-RA 70mm screw-in( the lens filter thread is 67mm so I am not clear why it is a 70mm hood) but I cannot locate such a hood. Anyone any ideas where such a hood might be obtained and at what cost? Ideally as I am based in the U.K. a U.K. or European source would keep postage costs down but I may have no choice in the matter

Alternatively what do other P645N owners use for the 45mm A f2.8 lens? It doesn't have to be a genuine Pentax hood as long as it fits the lens and accepts a filter as well
