Re: MZ-S: a couple of tips

2002-01-07 Thread Michael Perham

I've been away for a few days, so just catching up on my PDML 
news/views.  Actually  the pre-flash is there even if you do not use the 
AF360 remotely because it fires a control flash to measure the flash 
with the multi-zone meter system (P-TTL) and that is what I believe one 
sees through the viewfinder.  Of course if using the flash remotely, 
then there are a further series of control flashes so the camera and 
flash communicate info to each other.  All appearing as one contiguous 
flash with no apparent shutter delay.

Cheers,  Mike.

Hi Pat,

As Michael indicated in his post earlier it seems that you are actually seeing 
the pre-flash containing the data transmission to the remote flashes happening 
before the actual flash for the exposure.

The hotshoe cover and eyepiece blind can also fit in the two little pouches
that come with the neck strap.  I always place them in there because I am
very forgetful and am always misplacing small objects.

Subject: MZ-S: a couple of tips


 Recently, someone complained that it was inconvenient to set the mirror
 pre-lock on the MZ-S.  Unless you use the self-timer frequently, you can
 select the pre-lock and forget it.  If you have the BG-10 grip, you can
use
 the IR remote, which is far more convenient anyway, and it only costs $25
Cdn.
 The remote 'e' is so small it fits in the pocket on the MZ series
neckstrap
 (the hotshoe cover and eyepiece blind can both fit in the other pocket).
This
 also means you don't need to buy and carry an electronic cable release, as
the
 remote is actually handier.

 Pop Photo thought the hold switch was useless, but it could be very
handy
 when handing the camera to someone to take a picture of, for example, you
and
 a friend.  When doing this, you should make sure that AF Single is
selected,
 as a helpful bystander won't notice whether you and your friend are in
focus
 or not (if AF-C is selected), and your one-time special shot could be way
out
 of focus (happened to me).  Hope this isn't too obvious, but it might help
 someone.

 Also, last month, while using studio flash cordlessly (using the MZ-S's
 built-in flash to trigger the studio flash), I picked up the stereo remote
to
 turn down the music and found it triggered the studio flash (Yamaha
stereo,
 Bowens flash w/Bowens IR trigger).  Could be handy for cordless light
 readings.

Re: MZ-S: a couple of tips

2002-01-03 Thread Pat White

Hi, Rob!

The studio flash was triggered by the MZ-S's built-in flash.  The IR trigger
on the Bowens unit is really sensitive, and any flash will trip it,as well as
stereo remotes.  I've started to test lighting and poses with my old Polaroid
Spectra camera, as its built-in flash will also trigger the studio flash.
Polaroids with studio lighting are a pleasant surprise.  They're quite nice.

To minimize the influence of the MZ-S's built-in flash on the photo, I set
PF10 to 2 (sets the built-in flash as a wireless flash controller), but the
difference seems minor (your mileage may vary).  For the same reason, when
using the Polaroid, I set the brightness switch to dark.  The built-in flash
on my MZ-5n also allows cordless studio flash, a nice change after
occasionally pulling over light stands when backing up with a long lens, as
the F5P(L) TTL cord (used with a Metz 40MZ-3) isn't long enough.

Now here's something I'm curious about:  I can always see the flash in the
viewfinder, although that's supposed to be impossible.  It's more noticeable
with the big flash, and when I first got it last summer, I worried that the
the sync was off, but the pictures look fine.  I don't see an image, but a red
flash in the finder.  Could there be light spilling around the mirror?  Back
to you.

Bruce Dayton wondered:
 I have 3 AF360FGZ's.  I can place one or more behind the camera body
 and they still fire without being about to *see* the popup flash.  I
 have read that section many times, but am not sure to it's
 explanation.  I'll do some more experimenting and report back.

Try it in a room draped in black velvet and see if that makes it
fail.  :-)

I know that with a normal optical slave, it doesn't take much
reflection to get the slave to trigger off a non-line-of-site
on-camera flash.  Figure with all that information being sent
back and forth, the situation described sounds a lot more 
finicky, but I could see it working...

Actually, I first noticed this with the MZ-5n, which doesn't do a pre-flash,
as far as I know, and I was using a PC cable with a Pentax hot shoe/PC
adapter.  It seems like I can see it with or without the built-in flash
activated.

Rob,

I've been playing with it some and it is *not* an I/R trigger.  It is
a radio wave of some type.  The flashes do not have to be line of
sight of the body and yes the MZ-S body generates it.

Actually it's neither IR nor a radio signal that communicates between 
the MZ-S body and the remote AF360 flash.  It is the built-in flash that 
communicates this.  The following directly from the manual; page 37.

The following transfer of information is done with the built-in flash 
when the AF360FGZ is used wirelessly before emitting the flash.
1) Shutter button is pressed
2) The built-in flash emits a small control flash (relays the flash mode 
of the camera)
3) External flash emits a small control flash (relays conformation of 
 subject)
4) The built-in flash emits a small control flash (relays flash amount 
to external flash)
 *The built-in flash will emit a small control flash one more time 
after this to relay the flash time when HS (High-speed sync) is set.
5) External flash and built-in flash emit main flash

You can also have the built in flash not fire as part of the main flash 
as one of the PF choices.  And, I might mention, all this happens so 
fast is appears to be only one flash.  Even when the AF360FGZ is mounted 
in the hot shoe, there is a pre-flash that uses the TTL multi-point 
exposure meter to make a reading and that is why the flash exposure is 
so good. However, as I have said before, you can actually see the flash 
in your viewfinder, which normally is not the case as the mirror is up 
during exposure and the main flash.  And my only criticism is that 
people who are prone to blink at a flash, do so during the pre-flashes 
and the main flash/exposure catches them with their eyes closed.  

Cheers,  Mike.

Hi Bruce,

I don't know if you have ever used one of those Wein slave triggers but those 
things are so sensitive they can practically be in another room and with just a 
little light leak form the main flash trigger the remote.
