point and shoot camera with underwater housing.


Add an external strobe. Makes all the difference. More difference than which camera you end up choosing.

Having said that, consider if you like to take small critters. Point and shoots vary quite a bit in their minimum focusing distance.

The final criteria is ease of operation. Look out for cameras with accessible On/Off switches.

Olympus and Canon are generally the most popular.
 

a friend recently bought Oly XZ-1 w underwater housing and some lights. Not cheap :)
Can consider that if you are 'regardless of budget'
 

zero.. is the colour accurate? my friend recommended cannon ixus range over the powershot range. is it true that ixus is better?
