and that was exactly the question - I hope that actual owner will see the question... of course I can wait for the hood to arrive and buy the cap then, probably I just have to buy 67mm cap, as I have 62mm anyways and 72mm seems to be bigger than image shows, plus I have one already... 67mm then is the only alternative, if it will not fit then loss is $1-2
... the bigger problem then is what to do, if neither 62, nor 67, nor 72 will work - probably hit some stores and really try to find a push on cap or DIY
