5 pin bulkhead, brand? installation? nexus d300

I have a nexus d300 using fibre optic.

Want to convert for ttl (quicker sync )

Can anyone recommend a brand, or website to buy?

How about self installation? Recommendations ,comments, things to avoid?

Cheers

It sounds like you want to retrofit a Nikonos type (or alternate type such as S6) bulkhead to your housing to use a wired synch cord. The housing industry is not standardized very well when it comes to the hole in housings for bulkheads. It can be a plain hole, have metric threads (more than one size!!), or have inch sized threads. You need to figure this out for your housing first. For example my Seacam housings have M14 holes - 14mm in diameter with metric threads. Subal uses this size as well. No idea about Nexus - it could vary among their housing models. Contact your Nexus dealer. Some dealers here in the US have bulkheads on their site.

For example:

TTL? How?

I agree with Tom's mechanical observations above, My preferred method of obtaining suitable bulkhead connectors is to buy obsolete housings via eBay. Generally each housing provides 2 bulkheads...

Installing a bulkhead connector provides an electrical (vs optical) connection. But you still have the electronic challenge...a TTL converter is likely required...What type of strobes do you have? What type of TTL does your camera support? Digital? Analog?

I have adapted several P&S housings to incorporate Nikonos style wired bulkhead connections. Out of the box this gives me manual strobe control.

No free TTL.

Modern cameras employ Digital TTL: Canon eTTL, Nikon iTTL and others...Strobes do not...well none that I know of - anyone know a strobe that natively supports any of the manufacturer proprietary wired digital TTL protocols?

My current understanding is that many (some, all?) underwater strobes support the ancient wired TTL protocols. http://www.camerasunderwater.co.uk/articles/engineering/ttl-flash\ provides an excellent reference for analog TTL. Thanks! All of my Sea & Sea strobes support at least one of these analog protocols. Welcome to 1990?

Digital TTL is a different subject. One that I am currently exploring via "My Strobe Controller Blog" on both Scubaboard and here on Wetpixel. There is no free lunch...

Seacam Seaflash models 250D, 150D, 100D, and soon the 70D support Canon and Nikon (as separate versions of each strobe model) digital TTL.

UW Technics company produces optical and wire TTL Converters, as serial product for Nauticam housings. But also available to order a custom made TTL system for other brand housings. All types bulkheads are available. No problem to make TTL system for Nexus D300 by optics or by wire.

Hi,
i have a D300 in a Hugy housing, with built in TTl, and a UK Germany housing without, which i can use in combination with a Weihkamp TTl converter.
You need to find out what kind of hole, with or without thread your housing has, find a fitting bulkhead and a converter that has the right protocoll for your strobe.
What strobes are you using, planing to use?
Except Subtronic / Seacam all strobes use the "standart" TTl type.
So you need to find out what converter inside or outside will fit.
