I like it for it's affordability and size.
I dislike it for it's lack of manual controls.
I haven't had any problems with the housing.
The bonus is it's stock sony, so it cost under $200.
(Olympus and Canon make similar stock housings)
It is definately the black sheep of this forum.
The camera of choice seems to be the Olympus 5050,
and for good reason as it has a stock housing and has manual settings.
I'm not sure of ther size difference, but it could be negligable.
Anyway here are some shots with the
P10/PHA, no flash.
For all of these I did have a sea and sea 16mm attached via an adapter ring.
The adapter ring lets you attach and change lenses underwater just like the sea and sea setup.
The pics are somewhat green, but i do dive in green water.
Like I said the size is mainly why I like it.
On land you almost don't know it's in your pocket.
In a briefcase or purse you definately don't notice it's there.
Underwater you can clip it off or put it in a pocket,
which is great for when you are doing other things where you don't want to carry a rig.
If I was going to be diving with the sole intent of taking pictures,
I would probably want a camera with full manual controls and strobes.
