What's a GPX? should we have a Pentax forum. I've never considered buying one before, but maybe now's time to buy a Pentax in the spirit of brotherhood? Thankfully, we didn't buy Sony. :?
You are welcome guys! I hope to add some comments and about the PX, which I'm testing for some time. It's very nice and easy to carry camera with certain problems, but definitely capable of taking some nice photos.
ZDP-189:
The G & PX cameras are Ricoh's tough and waterproof models. The G cameras are targeted more to industrial customers and the PX range is targeted to holiday photographers. It's also smaller, lighter and much less expensive than the G series. But despite that, it has very similar parameters of toughness and waterproof-ability.
