Not sure the square hood is big enough for 28mm on FF. It is labelled as LH-SA49 and made by JJC (as a "PA-SA49 replacement"). It can be found online for $10-$20. I got mine from the
German Amazon, not sure which shop. Its a clip-on hood, so it has its limitations, but I like it on the DA lenses that don't have bayonet for hood. It works okay on 28mm and 35mm on K-01, but I am not sure it is perfectly effective, but its better than no hood. I think Pentax used to make this hood for 35mm lenses back in the film days. Edit: Here is a link to the official page:

JJC also makes a DA 40mm hood knockoff, I think. They make a lot of hoods, for a much lower price than a genuine one.
