i just got the camera. The housing is still not shipping. After one day with it, I can say I like everything except for the fact in full manual mode, the screen will go dark as you select faster speeds. If I were trying to take a micro shot and don't want the background, I would set the camera for 250 @ f8. With this setting the screen is black.
I have looked in the 'Advanced Manual' but I don't see anything on this. In any other setting mode the screen stays bright.
This could be a 'deal buster' for underwater.
On the plus side, the screen is much larger than the 5050 to 8080s. The write speed in RAW as been improved (photoshop does not have a RAW converter yet).
The camera is very small! Very travel friendly, but at the cost of dropping the CF cards. Only XD is used.
The slave mode is here so that there is no preflash delay when using fiber links to strobes.
If I get fix the dark screen, I think I may like this setup.
