Control. I like to have control and play with the possibilities a working flash's exposure compensation can give. Also, I have been using this rig for less than 2 month, so I still need to check how the TTL works on a variety of light situations.

Thanks for your quick response, Interceptor121.

As I cannot create a new topic, I will use this one.
Looking for opinions to decide: Canon G15 + Patima housing X Sony RX-100 + Patima Housing.
With Patima housing, both cameras can use truly wide angle lens (W.A. is my passion)
In my opinion, Canon G15 + Patima has these pros:
-Hot shoe. Meaning you can use a sync cable and depend only on the external strobe recycling time to fire several shots
-Super fast lens, even using telephoto, with F/2.8
-More physical buttons. Meaning less hassle with menus
-Macro mode
-N.D. filter. very useful for taking sun ball shots
Cons:
-Historically Canon's slow auto focus
-TTL cannot be use in manual mode
-Smaller sensor

Sony RX-100 + Patima Pros:
-Bigger sensor
-TTL can be use in manual mode
-Much better video capabilities
-Fast auto focus
Cons:
-F/4.5 in telephoto
-Lack of hot shoe. You can only use optic cable, depending on the internal strobe which can take up to 10 seconds to recycle
-Lack of N.D. filter
-No macro mode

I would like to see your opinions

PS: Patima is about to release its housing for Canon G15
PS 2: sorry about my poor english grammar

Good dives and great pics to everyone!!!
