I specifically ordered both remotes as they serve totally different  
purposes.

The Canon alternative to the wired remote is good.

I use the wired remote with a tripod setup and the wireless when  
doing the self-portrait thing or sometimes on a copy stand.

For Christmas last year, my wife gave me a wired and wireless remote for my DS.

(This which blew me away 'cause she has always maintained that she
would never buy me any camera 'stuff'. She loves the pictures, but has
no interest in all in the equipment. )

Her intent was for me to keep the remote that I would actually use,
and return the other. It didn't take long to convince myself (and her)
that the wireless remote is not the best tool for shooting behind the
camera. Two different tools, completely different purposes.

(I kept both).

The connector is a normal 2.5 mm stereo jack plug. I connected such a
jack plug to my Z1 cable release which is a excellent switch.
The biggest problem is finding a 2.5 mm jack plug which is small
enough to fit the istD. The normal jack plugs are too thick around the
plastic part of the connector (not the metal connector itself which is
2.5 mm).

Hi Francis,

No mechanical remote connection on the DS, unless you get one of the velcro
strappy things to go over the shutter release. 

The IR remote isn't reliable from behind the camera. The signal can bounce
around the room, but it depends on what's in the room. 

I got a reasonably cheap Chinese version of the DS electronic remote on ebay.
Nicely made.

RE: flash questions

Simply move the flash away from the camera.
The angle between lens and flash directions is crutial in getting/avoiding
red eyes (whis actually is the flash light hitting the backside of the eye
apple (the retina), in a place, visible from the point of view of the lens).
Perhaps 8 inches or less will do the trick!

So long as the flash has its own sensor and your use of bouncing doesn't

Assuming the ceiling is white and about 2-3M high, +2 f-stops should compensate

Osram Servo 18SC flash questions

2004-07-19 Thread Markus Maurer

my first and second message did not make it :-(


Hi Jens
thanks to your advice I had an eye for a slave flash and found a barely used
Osram 18 SC servo (with sensor) in a second
hand store for nearly nothing together with some nice filters and other
accessories.

Since I can not find a free copy of the manual an the internet and since
there is really no switch to set anything
on this flash, could you explain for me:

What does this "servo" mean in addition to the slave function, what's the
difference to the non servo model?
Do I have to care about anything when using it together with the AF280T from
Pentax as main flash?
I assume the Osram will always flash at full power and the main flash will
control the amount of light?
I think you told me that you have exact the same flash combination used
successful with analog bodies.
Is 18 the guide number for ISO 100?

thanks in advance
a (today) very happy Markus

Hi Alan
What do you mean by syncronizing?
I have a Metz 32 Z-2 and a 274 (AF) adapter (bought for Z1). I think you
must set the Super A to 1/125 sec (flash speed). If you set the lens to "A",
the Super A will choose apropriate aperture (for non flash/according to
ambient light and 1/125 sec.) and then fire the flash TTL-wise, that is to
give apropiriate flash light for the aperture, which the Super A have
choosen. The Super A will does not provide a facility to set the camera
aperture, accoreding to the possible flash-output, if that's what you mean?
This kind of automtics have been manufactured (AFAIR), but I don't remember
by which company?

The Z1 will adjust shutterspeeds (within certain limits) and the aperure
according to the used program, the flash and the ambient light at the scene.
all the best

I am trying to understand what it will take so as to enable an MZ-5n

What I am missing, is something to place the show adapter. Is there
such a thing as a grip with an attachment that screws to the bottom of
the camera? Could not find anything on Boj's site or on the Pentax
UK/US sites.

Also, is there a manual way to zoom these two flashes if one uses a
manual lens with the camera?

Finally, will they refuse to zoom/flash if used with an F/FA lens at a
focal length beyond their maximum?

Contrast-control flash questions

2003-01-20 Thread Joe Wilensky
Here's a question for those who have used Pentax cameras with both an 
RTF flash and a separate flash unit.

Let's say you have a PZ-1 or PZ-1p, which has the built-in RTF flash 
and can do true contrast-control flash with some of the newer flash 
units (using TTL flash and a slightly slower shutter speed than 
maximum flash synch, the separate flash and the RTF flash fire at a 
2:1 ratio).

But what happens if you use the AF-280T, which is the only flash I 
have with bounce/swivel capability? It doesn't do the 
contrast-control thing, however. But if you fire the AF-280T (let's 
say angled toward the ceiling) and the RTF flash together, you still 
get TTL flash, but what's the ratio? I assume the TTL would shut off 
both flashes at the same time, but perhaps the more powerful one 
would dictate the overall exposure? Would this be workable for bounce 
flash with a little fill-in flash via the RTF? Or should I get an 
AF400FTZ or AF500FTZ?

Joe



Some Flash Questions

2003-01-16 Thread Gregory L. Hansen

I've been looking around a bit more at flashes.  The real world has hit me
pretty hard so I'm not in a hurry to buy anything, but I want  to have
some idea what I'm looking for when I get that straightened out.

Some flashes have TTL modes but no manual mode.  What exactly does that
mean to have no manual mode?  It won't work on a K1000?  There's no way to
turn off TTL metering when used with my ZX-L, even if I have the camera in
manual mode?  I fear that sometimes light reflected from foreground
objects will throw off the exposure, and manual mode would be best then.

Yes.

The camera is still metering for the ambient light. You've set the
sperture/shutter speed for a correct ambient exposure. If you dial
in -1, the camera is telling you that the manual settings will give
you a stop more than the -1 setting on the dial.

In other words, you've told the camera you want to underexpose by -1,
and it's telling you you're a stop over -1, which is just what you
want.

Maybe the confusing part is that you expect the meter bar graph to
line up at -1. It's not. It's going to line up in the middle, the
difference being that the middle value is -1.

Now when you hit the shutter, the flash/camera doesn't care about your
manual settings, it's going to shut the flash off when it senses it's
hit -1.

Therefore the ambient exposure will be correct, the flash will be a
stop below.

2002-12-13 Thread Jerome Daryl Coombs-Reyes

[disclaimer: these are pretty basic questions, but hey! I never claim to
be more than a beginner... but a "professional beginner", ofcourse! ]

It's been said on numerous occasions that the exposure compensation dial
works as flash compensation in M mode. Okay, so if I understand this
correctly, for half intensity, dial in -1 EV of flash compensation; for
one-third fill, -1 1/3 or -1.5 EV; for one quarter, -2 EV. Well, even if
that scale is not quite right, the main point is that for less flash, I'm
supposed to dial negatively correct? Well, if the answer is yes, then
please answer the following:

Consider a conventional fill-flash setting. I first metered the scene on
Program mode. Then I set the same exact settings manually (now in M mode).
Then I flip on the flash unit.  Initially, the compensation bar graph
stays at zero as expected. But as I turn the comp. dial to the negative
side (less flash?) the bar graph goes up (towards the over exposure side).
Is this supposed to happen? Is what I expect to happen (less flash)
actually going to occur even though the indicators seem to say otherwise?

Of course, I could probably answer some of these questions by just
shooting some shots, and taking some notes but I figured there is no need
to "waste film" when I have such a panel of experts before me [hoping that
flattery will get me everywhere].

Thanks in advance,
  jerome

ps...  I now see that it pays to take the camera out of the bag sometimes
even when you're not shooting. seems like an obvious thing to do (for
learning purposes), but I unfortunately never bother with such things
until I'm out taking photos, and by then it's too late! hmmm... lesson
learned.

tom,

That and cost are the two current deterrents.  I really would like the
power that it has.  It will work with my leaf lenses and P67II TTL and

How do you figure that? The 500 has a GN of 32 at 28mm, the 280 has a
GN of 28.

Of course how often do you shoot at 28mm? The zoom function isn't some
gimmick, it actually works. Load up some 800 speed film and a
telephoto lens and you can illuminate someone from a few hundred feet.
If I'm at 28mm I'm right in someone's face, or at about 15 feet doing

What's the 900 kit?

The original poster said he found the 280 insufficient for his needs
at ISO 100. I would be curious as to what exactly he's shooting. I
almost never shoot below 400 at weddings unless I'm outside with the

Bump your film speed up to 400 and you've doubled the power of your
flash. If you're worried about the resolution, 35mm NPH does fine up

the guide # is accurate with a 85mm F1.4 lens with the
zoom head set to 85mm. The AF500FTZ is Pentaxes most
powerful flash and it does have some range to it (
only a bit more than the 280 ) but the trade off is it
eats batteries and can take forever to recharge. The
price you pay for sun tanning power :-)

AF-500-FTZ FLASH QUESTIONS

2002-10-01 Thread Frank Knapik

Hello. I have a couple of AF-500-FTZ questions:

1)Guide Number-164/ISO 100.  Is 164 an accurate guide number for this flash? I realize 
that flash manufactures tend to over rate their guide number, but I thought I read a 
comment here that Pentax uses the flash zoom head at telephoto position to obtain the 
high guide number. I am not sure that has any relevance to the actual guide number.

2)I am looking at this flash for Wedding and other event photography. I have the 
AF-280-T, which I like a lot,but I need more power. I like to use Reala film, but with 
an ISO of 100, I find the AF-280-T not quite sufficient. 

I will be using the flash with my PZ-1P. I also have an LX but it is my understanding 
that the AF-500-FTZ is not compatible with it.

adjustable power manual flash is very useful for adjusting the 
ambient/fill ratio when doing daylight fill flash. For example
if you want a 1:1 ratio, choose a fstop/shutter speed for
ambient light and then adjust flash power manually until it gives
correct exposure with the fstop already in use.

also allows extreme closeup work while keeping the f-stop
managable with fast film.

third less used feature is the very low power setting
allows shortest possible flash duration which is desireable
if your trying to freeze extremely fast action of some sort.

Flash questions

2002-07-30 Thread Sveta & Alex Shurygin

Did anybody try or used Vivitar 730AF flash for Pentax?

The spec claims lots of features for very little money, but is unclear
regarding Pentax model.

Also, it seems to have 1/16 power mode. I tried to figure out, how this can be
used? It looks like many f-stops (4?) below the meter reading, so it can
hardly be used for fill-flash. Or am I wrong?

In general, how important are these power settings (1/2, 1/4, ) on
high-end flashes? Could they be used for flash exposure compensation, or they
have diferent purpose?

Thanks

RE: Flash questions

2001-11-20 Thread Karasch, John

The import version of the AF280T is available for < $120 at Focus Camera.  I
bought one, and it's exactly the same as the domestic version.  Some people
think that the warranty is invalid for import versions, but Focus says they
will make good on any defect.  Two points here:  (1) a problem is unlikely,
and (2) $120 isn't exactly a life-altering purchase, even if it went bad.

Re: MZ-S flash questions.

Nick,

The way I read the manual (page 71 of the US manual) the metering
remains on the central section when using the spot meter and does not
follow the focus points.  There is nothing in the operation of the MZ-S
would lead me to believe that the metering follows the focus points in
the spot metering mode.

Page 91 of the manual says that the high speed sync can be used in the
wireless mode.

Possibly, however, it is amazing what creative control you have

The flash should rotate on its mount, so shouldn't cause
problems.
