Since flash brackets have come up, I may as well mention some things we've 
come across...

The flash flip brackets have the advantage of keeping the flash over the lens.  
They also keep the flash's rectangle of light in alignment with the camera's 
rectangular image area.  This works great with smaller flash units, and we've 
used Sunpak 383 / Vivitar 285 sized flashes successfully with the flash flip 
brackets.  We've also used some Minolta flashes successfully.  The 383 and 
285 are fairly small and lightweight, and the Minoltas lock on nicely with 
their great flash shoe.

The major problem we have is with a Metz 54 on a Pentax exension cable 
( Promaster brand cable, and we have several ).  The flash is heavy and 
eventually wiggles loose from the hot shoe mount on the flash flip, even when 
it is tightened down as hard as we dare go with the plastic screw on the 
hotshoe.  Try connecting your flash to a hotshoe, then wiggle it off by 
twisting slightly left and right while pulling off gently.  The big digital 
flash loses its digital connection long before it loses its large center pin 
fire connection, so you get a bunch of photos with bad flash settings before 
it finally stops firing, soon after which it falls off entirely.  This 
happened to us, causing great frustration before we figured out what was 
happening. The solution so far has been some plastic zip ties, one between 
the hot shoe extension connector and the heavy Metz.  This zip tie keeps the 
flash from coming off the hotshoe.  Another one is used to keep the hot shoe 
on the flash bracket, although this one probably isn't needed.

Supposedly other brands might have a little pin which sticks down to keep the 
flash from sliding off.  I know the Minolta would never do this.  I wish 
Pentax could come up with something.  Maybe they have.  I see an empty hole 
on the hotshoe on the DS, but I havn't seen a Pentax brand flash up close to 
know if it has a pin to fit into this hole to keep the flash on.  If so, 
there will probably be ten responses in a few minutes telling me so.  I do 
know that the Metz 54 doens't have any pin to fit into this hole.


A camera rotating bracket keeps the flash upright all the time but rotates the 
camera.  The flash is still over the lens, but the rectangle of light stays 
horizontal even when the camera goes vertical.   This doesn't take full 
advantage of the flash coverage, but it does reduce the amount of strain on 
the flash to hotshoe connection.  We might go this route.


I also have a bracket which is a folding L bracket, found in many local camera 
shops.  Metal, made in Japan, click stops at several rotations, and the hot 
shoe tilts.  You could put a flash onto this bracket and have the flash up 
high and slightly to the left for horizontal format, the click stop the 
bracket to rotate the flash way to the left which puts it far over the lens 
for a vertical.  You can also click stop it to 45 degrees to the left for a 
compromise.  When you are done it folds up into your camera bag.  The problem 
I had with this bracket is that the tilting hot shoe would flop over with a 
heavier flash unit, so I disassembled the handle, drilled out the spring 
loaded tilt, and put in a pop-rivet.  End of tilt problems.  The 383 can be 
rotated and bounced any direction anyhow, so I didn't need any tilt.  This 
bracket is used for the secondary camera for a wedding processional, with a 
simple on camera flash.  The flash flip bracket is used for the main 
processional camera with both a flash and a radio transmitter for the second 
light.  It's great for what it is, but it flops around a lot when you are 
using the secondary camera.  The click stop L bracket just stays how you set 
it.  Maybe someone will add a click stop to a flash flip bracket some day.


All of which is to say that a heavy flash unit doens't necessarily go well on 
a flash flip bracket.  I am beginning to wish that we had gotten a handle 
mount flash instead of the 54.  


For the curious, I keep the Metz 54 on auto mode using its built in sensor, 
instead of TTL.  Fairly good results, and my wife knows how to dial the flash 
up and down with the flash control, or dial the background up and down with 
the shutter speed.  The 54 does follow the camera's aperature changes, unlike 
the 383s and 285s which I use.
