well, gee.  What an interesting question.  I think I would wish all my friends here that amazing shots just drop right in front of them (grin)
And to I have only had my Pentax K10 for a few months.  I also have a hubby who thinks you only need a camera that costs about $100.00 bucks so I am trying to work with a lens from my 35 mm Pentax.   I would wish for a macro lens that really works with my camera!
