Thought I had this all understood about Sunpak flashes. After more
checking, I find that Gary is right. I had info on the 422D which does have
removable module. I had assumed the 433D would be the same. DUH!
As Gary mentioned, the 444D does have modular shoe.
I would not compare Vivitar 283 or 285 with the Sunpak 4xx flash units.
That would be better done with the 3700, 4600 or 5x00 flashes that have
interchangeable modules. The 3200, 3300, 3500, 3700 as well as the 4600
have the same module (D/x). The 5200 and 5600 have the P/xx module. Both
series allow a DSC-x adapter that permits TTL off-camera flash.
There is also a macro adapter using fiber optics to allow close monitoring
of flash at subject.
Someone also asked about using a 283 on an OM-10. The question seemed to
hinge on power of flash through shoe into the camera electronics. An easy
way to tell if the flash trigger voltage is too high is to place your tongue
on the flash shoe, turn on the flash and then trigger it with the open flash
button. If you burned a hole in your tongue, the voltage would have been
too much for the camera. ;-). JUST JOKING!

One or two other distinguished Zuiks made similar comments wrt
this strobe and Sunpak modules. I believe there is some confusion
regarding this issue, so pls allow me to clarify.
The Sunpak 433D is a fixed mount, "single system dedicated" flash,
i.e. it comes pre-configured/dedicated for a specific camera, and
this configuration is not supposed to be user modifiable (although
it may be possible to do so with some spare parts from Sunpak).
The OT-1D (OM) interface module is one of the numerous dedicated
TTL modules which Sunpak offers for its line of "multi-dedicated"
strobes, such as the 444D, the 622 Super, and the two ring flashes.
These modules _are_ user interchangeable.
Having said that, I concur with other Zuiks' evaluation of the
433D flash: it's a very well designed, powerful and flexible unit,
which is highly effective on an Olympus body in OTF mode, on- or
off-camera.
However, beware that if used in Auto mode, the 433D must remain
either on camera or very close to it, as unlike the equally great
Vivitar 283/285 flash guns, the 433D light sensor is non-removable.
But then, the very popular Vivitars do not offer TTL dedication...
Oh well, no one said this was supposed to be easy, right? :-) :-)
