RE: Wierder! was-- EC with TTL Flash on ist D?

2004-12-04 Thread Jens Bladt
I did a similar experiment.
The result was that there are only small differences visible. However, they
are there!
The difference between  -1 and -2  is just visible to the eye.
Take a look:

Emne: Wierder! was-- EC with TTL Flash on ist D?


Here are 7 small pics taken with the ist-D and 500 FTZ:

http://www.donsauction.com/pdml/flashtest/FlashTest.htm

The chair is light/medium brown.
They are 1 stop of EC apart from -3 to +3.
No difference appears until you reach the plus side,
+1, +2 and +3 show an increase in exposure.
The -3, -2, -1 and 0 are all the same.
These are at 1/150th, Manual mode, ISO 400 with
a Vivitar 70-150/3.8 set at 150mm/f8.0 at 20ft.
Any ideas on why +EC makes a difference and -EC doesn't??

I have very few problems with the AF360FGZ or AF140C on the *istD. As good as 
with the MZ-S.

I Just tried the RTF: Same result, just a bit greater variations, thoug. I
got one tiny overexposure (still within the acceptable) at f4 (open). This
is not an issue to me. I would never use the RTF for anything else than a
fill in flash. Never as the main light source (I own more TTL flashes than
cameras).

Jens, see what luck you have with the built in flash.
I'll duplicate the tests with the 360 and the 500 and see what happens.

I have made some test shots (emailed to a list member) with my *ist D and
the AF500FTZ flash, using TTL-flash metering.
I have used P, P(Tv), P(Av) and M settings. And quite frankly, I can't seem
to get one faulty exposure no matter what I do, except perhaps from shots
where the flash is out of range (long distance).
I have even tried to set the camera to "Auto Sensivity Correction if out of
range" - which means auto ISO setting if necessary. This didn't cause any
bad exposures either - I still got good exposures. All shots were very
usable and the exposure would at the most be perhaps 0.3 or stop or less
off.

How come?
What am I doing wrong here?
What must I do to get some wrong exposures, like everyone else seem to get?
Am I the only one who has a *ist D, that works just like most other Pentax
cameras, manufactured after 1983 (P-series exempted)?

I guess I'll have to do more tests with different flashes.
If I'm lucky I may be able to get bad exposures too.

I don't understand all this exposure failure talk about the TTL-flash and

system I have used (Super A, PZ-1/PZ-1p and MZ-S). I have noticed small

Maybe the prob come from Pentax using only old CW with flash rather

Get real.
My 20 year old LX (centre weighted) is more accurate than my istD.
My Super program (centre weighted) was more accurate than my istD.
My wife's MZ-5 (not the newer MZ-5n) is more accurate than my istD.
I am of the opinion that the problem is the new technology isn't as

I have all sympathy for any kind of malfunctioning the camera
suffered. I would have blown a transistor or three in its place.

Not an expert in anything, but I think you have too much space to fill
with the flash. Did you get TTL-flash confirmation in the first one
for example?

The pro in a friend's wedding in October was using a Nikon D. He told
me that flash is all over the place.

This is typical of how Pentax TTL flash exposure works for me. You 
will note the exposure is correct in one of the four pictures.

RE: EC with TTL Flash on ist D?

Just to make sure it wasn't lack of caffiene this
morning, I tried this again.

This time at f8/150th, ISO 400, 10ft (3 Meter) distance.
Built in flash, Manual mode, f8 set via aperture ring.

The histogram at -3.0 EC is virtually identical to the
one at +3.0 EC.
Wierd!

Jens, have you tried this in Manual mode with
an M lens on the D?
I'll look around in the setup and see what I can find.
I saw NO exposure difference over 5 stops!

It does. Z-1/Z1p did too.
I don't understand all this exposure failure talk about the TTL-flash and
the *ist D. My *ist D works pretty much exactly like any other TTL-flash
system I have used (Super A, PZ-1/PZ-1p and MZ-S). I have noticed small
diffrerences depending on which FLASH I use. My AF280T over exposes just a
little, but my all my different Metz flahses hit bulls eye IMO. So I can't
really complanin about the camera. Works fine for me!

Could there be any custom setting, that will influence this - perhaps an
auto sensivity (ISO) setting ?

I just took a series of shots using an M type lens at f5.6 and TTL
flash on the D in Manual Mode at 1/150 second and ISO 400.
I was about 4.5ft (1.5M) from the subject.
Used the pop up flash, room was very dimly lit.
At EC settings from -2.5 to +2.5 all of the shots are *uniformly*
overexposed.
What gives, does EC not affect TTL flash in manual?
What does one do in this situation?

What gives, does EC not affect TTL flash in manual?
Exactly my experience... however I've found that it's generally pretty 
accurate. It's just those few situations where it refuses to cooperate!

What does one do in this situation?
If you're using the inbuilt flash... cover part of it up or similar. If 
using an off-camera flash, point it partly away for example... pretty 
crude but hey, what's the review screen for (-:



EC with TTL Flash on ist D?

I just took a series of shots using an M type lens at f5.6 and TTL
flash on the D in Manual Mode at 1/150 second and ISO 400.
I was about 4.5ft (1.5M) from the subject.
Used the pop up flash, room was very dimly lit.

At EC settings from -2.5 to +2.5 all of the shots are *uniformly*
overexposed.
What gives, does EC not affect TTL flash in manual?
What does one do in this situation?
