My hand? I dunno. I can't justify paying $100 for hood on $250 lens.
If you buy the lens new or mint second hand, the hood should be included. True, the Pentax 67 hoods are interchangeable with some lenses (not all!).
I agree they are exhorbitantly priced bought new, and eBay sellers seem to think they can get away with a killing pricing them so high that you could buy pearl ear rings as a better (and wiser) investment...
BTW, if anybody is buying the SMC Pentax 67 55mm f4, I have a minty PH-SA 77mm square hood for it (the person I sold my 55/4 lens to didn't want it).
Will post overseas. Dunno what price I should put on it...
