In Topic: Problems: new Nauticam housing w/ Canon 7DII

You most likely have the AF assist on still which is the problem for the camera’s internal flash.


Settings,

 

If you want to use TTL, keep the camera in TTL mode and then put the INON to STTL, right dial to 12 o’clock and the button on the bottom right should be OUT.

 

If you want to use manual, go to flash settings onthe camera, turn to Manual mode, turn to 1/128th output, put INON into M mode, use right dial to modifiy output, bottom right button should be IN (or the magnet should be IN for the Z220).


The AF assist will only activate in low light and let’s out a series of short flashes to aid autofocus. This needs to be turned off.

Leepix,

 

Do you mean you have camera and housing already that you want to use?

Hi Nick. I’d be a little wary of the G7X if I were you, it does not behave like most other compacts so needs some consideration. If you are thinking of going wide angle, the G7X is particular in that its lens is shorter when at its widest. The result of this is that if you screw a wide angle lens to the front of the standard port, you are left with a large air gap between the camera lens and the port glass with a result that the corners of the image become very soft and out of focus with heavy vignetting around the borders of the image. The alternative is to zoom in which then means you lose much of the benefit of the wide angle lens.

 

Nauticam have overcome this issue by offering interchangeable ports for this camera, a shorter port for wide angle and a longer port for macro. When you have the short port installed, you cannot zoom in beyond about 40mm as the lens extends and hits the glass. This does mean that you lose flexibility that you would normally expect with a compact camera but you do end up with good image quality for both wide angle and macro. As far as I’m aware, other manufacturers do not offer a similar solution.

 

We have sent a setup to a French magazine, Chercheurs d’Eau, who are currently running tests with the Nauticam, Isotta, Recsea and Ikelite housings for G7X with a variety of wide angle lenses so this will be worth watching.

If you are looking for flexibility to change from wide to macro underwater, I’d still personally think the Sony RX100 Mk2 is the winning choice for underwater. This camera though does not perform well underwater for white balancing and the flash recycle time tends to be longer than the Canon.

I have a Nauticam Rx100ii here in front of me now and I cannot find a control that I don\t have access to from outside the housing.

No, the brackets have been redesigned to enable you to use T-plates on the handle tops, and keep the brackets.
