Thanks Mike.
Top Dawg housings are without doubt the most versatile and affordable of all the housings.
That being said with that versatility there is a little compromise. ( no flip filter / no microphone / flat port )
The basic functions are accessible power on / off rec / stdby , zoom , manual focus / auto focus select and if your camera supports it - photo mode ( switchable ).
It is possible to get them to manually white balance by preselecting manual white balance mode before putting the camera in the housing.
If you power the camera down and restart it the whitebalance will reset - certainly not a one button push but achievable.
I have found the Top Housings to be very popular with people starting out in the video world.
People find a lot of comfort in knowing that they will always be able to get a camera that will fit / function in their housing - not to mention the ease of upgrading their camera as time goes on.
