Another of my endless supply of questions for the experts on the List...
what is a reasonable limitation on the load that a Shoe 4 can support on
an OM-2n?
[snip]
I have and use a (not cracked) Shoe 4 on my OM-1n. Your concern regarding
load limit is shared by many on this list. I've never felt comfortable
with the T-32 directly mounted in it although I have done it a couple
times, albeit carefully. The T-20 directly in the OM-1n Shoe 4 worries me
much less. I would *not* use the flash extender in it with any flash.
My routine use of the shoe 4 on the OM-1n is with one of several potato
masher configurations: T-32 in a BG-2, Metz 40 MZ-3i in a Metz G-15 or
G-16 (Metz version of a BG-2), a Sunpak 544, or a Sunpak 555. I'm still
considering finding a used Sunpak 522 (for which I have an OM dedicated
module). Also considering a Metz 45 CT-4 or CL-4.
The BG-2 poses problems with using anything but an Olympus flash with it,
even if it has a dedicated OM Shoe 4 type foot on the bottom. The left and
right plastic walls surrounding the BG-2's shoe interferes with sliding
most non-Olympus flashes into it, including the Metz and Sunpak dedicated
modules that mount to the bottom of their respective dedicated flash
heads. Furthermore, the grip can only power a T-20 or T-32 with its "C"
cells through its 3-pin connector. Anything else that might fit, including
an Olympus F280, cannot be powered by the grip. The F280 has a cutout on
the front that mates the connector mechanically, but no pins. BTW, the
BG-2 has an internal voltage inverter and its "C" cells provide high
voltage power to "T" flashes on the order of several hundred volts. It's
why a T-32 recovers very quickly when powered by a BG-2 with "C" cells in
it, even after a full dump.
The BG-2 can be wired to the OM-1n Shoe 4 with a TTL shoe cord. The other
method is a .3m or .6m (coiled) TTL cord and a TTL Connector 4 which I also
have but don't use as often. The Metz grips and 45 C[T,L]-4, and Sunpak
522 and 555 potato mashers all use cords with dedicated modules for the OM
system's shoe 4. The 544 uses a PC cord and I plug it into a hot shoe
adapter instead of using the PC socket. The proper module and cord forms
the equivalent of the Olympus TTL shoe cord. Creates much less strain on
the OM-1n's Shoe 4. I've never had any concerns about using any shoe
mounted flash in the OM-2S or OM-4 hot shoes.
