Hi Lowell Goudge, yeah that is quite a bit of mathematics involved. Think I'll be able to get past that, provided I do not get the wrong measurement from the wrong part. lol Thanks a lot for helping me dig out that whole load of information.
Hi geauxpez, I see I see, will try and find out what are the angle of view of the 2 lenses. I checked out the rubber Hoya hoods, looks pretty good but somehow, something in me is itching to find the original Pentax hoods and it is driving me crazy! The bay is probably a good area to look for it, if not then I guess it would have to be the Hoya hood. Thanks for the advice.
Hi G8akjxc8954739 aka georgweb. = ) I got a lil lost when I read your guide on how to check the hood, but I think I get it, it is really informative. Thanks for your advice too. I really appreciate all the help that everyone has given me.
Thanks!
