In Topic: Is it a dumb idea to buy a new manual only strobe? And some other beginner qu...

You'll find as many opinions on manual vs TTL as there are days in a year, maybe more. When I was just starting UW photo, I found TTL to be useful in some cases, esp. if you can adjust the exposure on your camera by shooting in manual.. Now I shoot about 30% TTL and the rest manual strobes. Use TTL mostly for macro. I'm not familiar with the SS-2. I use the D1s and love them.

In Topic: Strange Shutter Delay on DSLR???

Here's a long shot to consider. I don't have a D800, but do have a D500 and I assume that the menus are similar. If the delay is consistent in length, there is a setting in Custom called Exposure Delay Mode. It's d5 in the Shooting/Display menu on my D500. I's assume that it's also on the D800.. If that is set to other than off and is somehow getting triggered while UW by pressure, that may cause the problem. This is different than Timer Release. Like I said, this is a real long shot.


Also try this. Make sure that you're using AF-C focus mode and set the a1, AF-C Priority Selection to Release. This will cause the camera to fire without the need to achieve focus. If this eliminates the problem, then the camera is, in fact, waiting for focus before firing and, for some reason, it taking an inordinate long time to get focus.


Like the others have said, misalignment is the most likely cause. The trick is to figure out which button is getting pressed to cause the problem.


I'm not familiar with the S&S housings, but I had an old Aquatica D70 housing that had plastic thread protectors on the end of the rods used to activate the buttons. Occasionally one of those protectiors would work itself loose and contact a button before it was intended to do so. This drove me crazy until I figured that just a slight amount of sea pressure on a button would cause contact with the button when the protector was slightly out of place.


Reef Photo isn't too far away. Consider taking the rig into them for a look.


Let us know what you find.

In Topic: dual to single sync cable

19 November 2016 - 04:47 PM

I used DS-125s and DS-51s up until a few years ago. I recall that Ikelite wrote somewhere on their web site that the caps were not designed to be waterproof. They were only intended as dust caps to protect the ends of the cables. I'd contact Ikelite before I submerged the cable connection with only the cap in place.


Looks like dragon above beat me to the punch.

In Topic: which o-ring maintenance on Inon Z240 Type IV?

31 October 2016 - 12:35 PM

There is nothing wrong with your approach as it has served you well with no floods. May be a bit of an overkill, but it works, so don't knock it.

Although I don't have Inons, I have used two sets of Ikelites and now have S&S YS-D1s. But o ring maintence at this level is pretty much the same. I don't remove the o rings when I change batteries, but I do inspect both the o ring and the seating surface with a light to insure there is no foreign material. I use a head light so both hands are free and I get good strong light on the surfaces. Unless I find something unusual, I only remove and grease the o rings every couple days. Plus I use a make up applicator or something similar to clean the o ring groove when it's been removed.

But the real cardinal rule is not to hurry when assembling your photo kit. In tech diving, it's standard ediquite not to talk to or distract a diver when he is checking his gear or suiting up. The same should apply to camera preparation. Don't distract me when I'm working on my kit.

Again, if it's working for you, why change?

In Topic: Back Button focus/Nikon D7100

06 September 2016 - 03:01 AM

Agree. Use AF-C. I use single point AF and move it around for composition., but that's a personal choice. Plus look at the shutter release setting, a1 and a2 on my D7000, assume it's the same on the D7100. I use Focus, others prefer Release. My eyesight isn't good enough to see focus anymore, so I left the camera make that decision. Also you may need to do an AF Fine Tune on your lens in case its focus point is off a bit. But that's rare with most lenses.
