Nautican D7100 housing AF-M switch not working

Recommended Posts

Since I purchased my Nauticam from Reef photo about 18 months ago I have had problems with the auto focus - manual focus selector switch. I've muscled through it but now I've had it. I am diving in about on Sept 18 so looking to see if anyone has any advice. The gear mechanism easily switching the camera from AF to manual, but it won't take the switch back to AF......there seems to be too much play in the connections. I suppose I can use the AF on function but that is cumbersome if you have a quick need to focus and shoot. Focusing with one lever and shooting with another is an extra step in my mind....acceptable for static maybe but not for fish. So has anyone had this problem and if so how was it solved? Is there a field repair or am I stuck sending it back to Reef photo? I am sure Reef photo would turn it around in time but the risk of not having my camera back for this trip is quite high. I tried to jam duct tape in the connecting areas to get rid of the sloppy movement but that didn't do anything. I also have enough know how to pull that part out if there's a "tightening" procedure, but don't want to go there is that isn't a viable solution.

 

Any help would be really appreciated.

The tray was redesigned early and replacement of the part is very easy. The shape has been modified very slightly to ensure that the button rotates far enough to prevent this issue.

 

If you are in the field already the best option I’d say would be to set the focus to the thumb lever and use this to focus. That way, the AF/M function on the camera is superfluous.

 

If you don’t want to do that, a quick fix until you can have the part replaced would be to build up the part which connects to the dial using electrical tape or similar.

Once you've tried back button focus you'll never go back to half shutter press. It gives you the best of both worlds. Leave the lever on continuous and back button gives you lock or focus tracking.

Hi Joe,

 

When you put the camera on the tray, make sure the two prongs sit correctly on the switch. You should be able to rotate it using the little dial on the tray and hear it click on both sides. Generally, if you do that, it works fine once in the housing. If not, we will get it fixed for you asap. Drop us an email at innovation@nauticamusa.com and we can get it scheduled for you. Make sure to note your trip date so our service manager can make it happen.

 

Regards,

Chris

 

P.S. I do agree with Eric though, thumb focus is great. If I was a Nikon shooter, I would glue that button on the front down and locked into the autofocus position, as I always seem to forget it is there when I pick up a Nikon. :)

Thanks, Eric & Chris. I did chat with Reef Photo yesterday and they know of the problem. I overnighted my housing to them. Their feedback was that the tolerances in the Nikon switch design are broad enough that the standard switch mechanism can't function across all bodies. Whether that's true or not, they have a fix, but it is a fix for my specific camera body, which I don't like. Either way, yes Eric, my go-to will be back button focus and the switch will become my back up.

 

Thanks for all the help.
