Olympus C-5050 (PT-015) Nikonos SB-105 TTL mode

Does anyone have any experience or suggestions to connect my Olympus C-5050 (PT-015 Underwater housing) to a Nikonos SB-105 strobe.

Would like make use the SB-105 TTL mode.

You will need to set the camera to the slave flash setting, to cancel the preflash. Then, run a fiber optic cable kit (you can buy these online from one of our sponsors) up to the slave sensor on the flash. Use the SB105's diffuser to hold teh fiber optic cable in place (Cut a small hole in the diffuser and plug the cable in).

You will be able to use the SB105 in manual mode only - set the power on the strobe.

Just a quick reply - just done this although my strobes are Sea&sea. Get in touch with Mike Finger (www.mike-dive.de). He knows all about this stuff, He is in Germany but speaks really good english and is extemely patient while explaining the options. Thare is an IR system available from Matthias Heinrich which will also work - but is not a s reliable as a hard wired system. I converted my housing to take a Nikonos bulkhead fitting. A circuit board inside sits in your hotshoe and converts the Oly signal into a Nikonos signal. Works full TTL/Manual settings, whatever you want. With optical you can get false triggering from somebody elses flash.

divingbiker,

I've looked at Mike Finger's site as well as the Henriech site. Can you please explain how you converted your housing to take the bulkhead? Did you actually drill it?

Thanks,

Glenn

pilotjima, I used the Matthias Heinrich unit. I tried the setup he sends with the unit but it was a little rickety for me, it worked but was rickety, I glued the outer unit to the housing and it worked really great in the local YMCA pool, I am going to give it the "acid test" on Cayman Brac next weeek. The location of the outer unit is a little tricky but with the glue I used it sets up almost instantly therefore you have to locate the outer unit exactly before applying the glue. I call it glue for lack of another word but it actually unites the polycarbonates, molecularly so I am told. I am using two SB105 strobes, one TTL the other in slave mode, until I can find a reasonablely priced dual sync cord. If you would like more information or pics buzz me at supe67@yahoo.com. zulu00

Hi sorry for the dealy in replying......Been in Egypt using my new set-up.....Absolutley stunning....

Anyway. I sent my housing to Mike Finger....he drilled it. Installed the bulkhead ( which he makes) and pressure tested the housing afterwards. He installs the bulkhead and tests free of charge. But you have the postage cost. The signal converter comes from Matthias Heinrich, Mike attaches it to his bulkhead.

You simply slide a small PCB into the hotshoe of the camera, then close the housing as normal. Then connect your strobe with a standard Nikonos lead. The system is not at all glitchy or problematic. No issues for me when doing 25 dives in 6 days.....400 photos, some bad but that was me not the kit. Saw other people underwater with similar conversion work. Works in all camera modes, M A S P or even cheating modes.....

This converter is normally applied to the PT-020 and C5060 system as described on this site by Craig Nelson. but Mike has now converted 20 or so PT-015 and C5050 systems in the same way.

Contact me direct if you want: mark.glynn@eptagroup.it. I can send you a picture of my conversion if it helps.

Would someone be ale to post a picture of their olympus housing with the Nikonos bulkhead fitted. I would be keen to see in as much detail as possible how this has been achieved.

Thanks

Hi ,

have a look at this : this are my mounting examples for the PT15
