In Topic: Strobes not firering. Nikon D70 with Ikelite case and DS125 and DS50 strobes

It is also possible there is a bad sync cord. Over the years i have had two ikelite cords that sometimes fire and sometimes not. Ikelite has updated the sync cords with more protection for the internal wires. Also if you shoot on full manual the camera built in flash will not pop up. I preset my iso and shutter speed and use the aperture setting for adjustment on most shots. Some i adjust shutter speed and aperture.

In Topic: Testing ttl strobe accuracy on a film camera?

31 December 2013 - 09:09 AM

Testing ttl from the Jim Church essential guide to nikonos systems book. This is for nikonos strobes but your strobe should work this test also. 

Part 1

Set shutter for a

Open aperture to the lowest  number f stop

Set strobe to ttl

Aim strobe into camera lens

Trigger shutter

If ttl is working it should be a brief flash and a quick recycle

If the flash is long and the ready light blinks for a full flash signal ttl is not functioning

Part 2

Set aperture to f22

Aim strobe away from camera

Cover the lens with lens cap or hand

Trigger shutter

If ttl is working it should be a bright flash and the ready light will blink as you have done a full power flash.

On the nikonos 5 if battery is weak the ttl system will fail also. So check your f100 camera battery too.

On a roll of film using macro or close focus shots if 1 or more shots are black the ttl is failing


In Topic: Wanted: D90/Ikelite housing/Strobes package

I have a ikelite 100a strobe. With a digital camera you can use this strobe in manual modes. It is in excellent condition. Includes strobe,arm and sync cord. i would like $350usd plus shipping. I use with my nikon d40x camera an ikelite  ai strobe which is the older version of the 100a strobe. Works very good.


In Topic: 2+ diopter for Megadome?

15 October 2013 - 12:06 PM

No the specs i gave you is from nikon site which is 12 inches from the sensor plane. And if you look at it 1foot  when set to 16mm and .9 foot when set to 20mm to 28mm. And the distance from the sensor plane to the exterior of the dome  is about 6 inches. You could shoot pictures from about 3 inches from the exterior of the port which would be hard for strobe position. It would be real close focus wide angle. On my system i use the +4 diopter as per aquatica chart. For macro i do add a second +4 diopter to get 1:1 macro but even with 2 - +4 diopter i  have about 6 inches from the port to subject so lighting is not difficult.
