Those Pentax lugs are very, very expensive -- around $90.00 posted, to Australia. Naturally, I railed at the ridiculous expense, for what they are. Eventually and after deliberation and inspecting another 67 fitted with alternative strap/lug combo, I settled on the
OpTech USA ProStrap alternative. These straps are in wide use on Hassies and Bronicas and can handle heavy weights without feeling like a burden. As for the Pentax lugs, I am chiefly concerned about chafing of the Pentax original lugs against the body. (I have seen this on a number of older, well-used bodies) A small point, but an important one that seems to occur by dint of the lugs' design (The OpTech has a plastic "lock" that apart from fulfilling its locking function also does
not chafe the body). I can understand the desire to own an all-original Pentax, right down to the lugs, but sometimes commonsense takes precedence over impulse when you're lining somebody else's pocket with gold ducats...:ugh:
