Underwater Photography
Or use the WR, if the housing does leak you've at least some extra protection, maybe enough to hold out till you're at the surface again.
As for housings, I've looked into them but they are quite expensive so didn't do it.
Therefore can't recommend you one.
This is a case for the K20D but the manufacture site is under construction so only have this for you link
There is a lack of choice for Pentax but generally speaking, for an SLR you won't get anything under £1,000 (and to be honest, if you did I wouldn't want to put my camera in it).
I would suggest, unless you are planning to become a professional underwater photographer that you at least start out with a compact underwater camera and see how you get on.
The most important thing when taking photographs underwater is to get as little water between you and the subject. That means as short a focal length lens as you can get your hands on.
Most importantly though, the housing. I looked around at specialist housings, and they're very expensive - for something which may not be used that often, e.g. upwards of £1000. I settled on a Ewa Marine flexible housing. There are a number of options for different depths (easily enough to cope with the PADI depth limit).
Pentaxophile is right about the 16-45, it's physically longest at the 16mm focal length - that's going to cause a problem with any housing.
You might want to consider an underwater filter (red or magenta depending on water colour) if you're going to be deeper than about 10 metres.
It's also good to have the option of a flash. If you're diving in clear water then you're unlikely to get back scatter, and you'll have good results. If you're diving, or snorkelling, close to land / seabed then there's likely to be a lot of sediment - which is a pain to remove in post production.
A fast prime might be useful for a night dive, but otherwise the 18-55 is perfectly adequate I would think.
Personally I don't think it's worth going crazy on the lens, unless you've got a professional housing, with an optically matched dome housing.
I'm going on a trip soon, where I'm going to try out a polarising filter too, as it may add contrast. I'll report back if any of my other lenses get used.
EDIT: This photo's better link
It's not that easy to find it for sale though, and there aren't many (any) reviews for it yet.
Doesn't the 16-45 extend too much at the wide end?
Some housing can take the length without a problem, just the problem of finding such a housing.
Also, if you really want a solid housing, then this is the most cost effective option; Diveross.

That one should take the 16-45.
The 16-45 is 92mm and doesn't seem to extend more than half the length.
The low standard port of the DRP200 is 158 mm and the tall one 178 mm so no problem for the 16-45 I think.
The price is around the £705 so that's quite acceptable, thank you for showing us that link geclinke
Hi fellow pentaxusers...
Is anyone of you into Underwater Photography. I am thinking of combining my two favorite hobbies, scuba diving and photography. However, I know that this increases the costs for a while. Therefore, I would like to ask for some advice.
I own a K20D the 18 - 55mm WR zoom, the 16 -45mm f/4 zoom and a FA 50mm prime. What kind of housing would you suggest or do you use? Which would be the best lens for UW? I am thinking of using the prime, because I don't think a zoom as applicable in a housing. Am I wrong?
Thanks for your help.

Hi Dan,
I used to dive but the old Arthritis finall caught up with me,
but in answer to your question, most scuba divers use the Nikonnoss.(If the spelling is wrong I'm sorry)
It is specifically designed for under water photography!
Ikelite make housings for most cameras, but do you really want to risk an O ring failing on your K20D, I would not!
My best advice, is to get along to the 2011 LIDS,(London International Dive Show.)
There you can get specialist advice on housings and lenses ect.
Go on the last day of the show that's when the bargains are to be found as most vendors don't want to cart loads of stock back!
Take only pictures, leave only Bubbles.
Kindest regards,
Peter

How do you zoom the lens with one of these housings?
You can't but Like Giles said.
The most important thing when taking photographs underwater is to get as little water between you and the subject. That means as short a focal length lens as you can get your hands on.
Since the DA16-45 is the widest and best quality lens that Dan has it's probably the most suited one and since you can zoom prior before putting it in the housing you've a range of focal lengths covered with one lens.
This way Dan can experiment which focal length is the best and he doesn't need to leave camera gear at the surface unattended.
