Actually, there isn't; there is nothing holding the sensor in place.  It 
only moves into position after the mirror initiates its swing up movement 
during an exposure.

That would be my idea, too.  What Rob is suggesting is equally possible, 
if a rather fly use of language by Pentax regarding its effect on 
battery life when in use.  But I can't imagine, in that case, that 
battery life would not be affected quite noticably and I haven't seen 
anything untoward mentioned.

I'm sure there is something (fixed magnet, spring mounting, etc.) to
keep the sensor fixed in place if SR is not operating.  The electro-
magnets of the SR system would displace the sensor from the central
'home' position - they wouldn't be needed to hold it in place.

Sorry, Mike.

I forget that sometimes I use motion picture lingo
when posting here.

Dutch angle refers tilting the camera at an oblique
angle for effect.

So my terminology is backwards.  "Activated" means actually working, not just 
turned on.  I would expect battery life to be essentially unchanged if it is 
only using power during an exposure.  But, if it was using the electromagnets 
to hold the sensor in place when not turned on, battery consumption would also 
be the same as if it was turned on.  Just more than if there was a passive 
location system.

What they said was:

"Since the SR system is activated only when you press the shutter
release, any effect on
battery consumption is negligible."

"Does battery life change while the SR system is engaged?
No, battery life remains the same whether the SR system is turned on or off."

Doesn't make total sense.  If SR is off, the plate would be free to move.  
Pentax specifically said that SR uses no power unless in action (not even when 
activated) so the electromagnets can only be used when SR is working.  There 
must be something locating the plate when SR is off/not functioning.

I don't think you'll have to. I was actually talking about the
horizontal-vertical sensor, which, afaik, is unrelated to the SR
circuit. All it does is tell the camera whether the picture was
landscape or portrait, and there is an option to rotate the picture
based on that data.

Also, I might be wrong, but I suspect that the acceleration I'm
talking about is way higher than the acceleration you put your camera
through when tracking a car as you describe.

Hmmm.  Actually it is.  When I'm using a long lens and framed tightly on
a car coming toward me (or going away) through "ess curves" the camera
is swivelling back and forth thoughout the tracking.  Might have to
disable SR for that.

Re: Re: Re: K10D - what's that rattle?

[Juan Buhler]

Fair enough.

The acceleration needed to confuse the sensor is bigger than that,
though. Besides, that vector would be along the lens
axis--perpendicular to the two directions the sensor detects.

The best way I found to confuse the sensor is to move the camera to
one side, and then to the other, pressing the shutter as I change
direction.

That isn't something you'd do for real pictures though.

It's based on electro-magnets which are on the floating plate on which
the sensor is mounted acting against permanent magnets affixed to the
body (front plate of SR assembly). So there is nothing to anchor the
floating plate until the electro-magnetic coils are energized.

Don't forget, too, that the normal panning motion is to
rotate the camera.  An angular rotation (even at a constant
rate) *is* an acceleration, and will be detected as such
by the sensor.

Try shooting a book or something straight down on the floor, fire off a
dozen shots, varying the angle slightly and see how the camera decides
what it should be - portrait or landscape.

Ahh, interesting, thanks Cotty. Perhaps it's common to
some DSLRs.

As I mentioned before, it's unusual but it doesn't
seem to affect the operation of the camera in any way.
So, I'm not going to sweat it.

It only moves in the one plane; moving the camera
forward and back it's nice and solid, only rotating it
on the axis of the lens do I feel it.

Re: Re: K10D - what's that rattle?

[Juan Buhler]

I think you are confusing acceleration with velocity.

When panning, you should move in a way that is as constant as
possible, trying to minimize accelerations. So no, the orientation
sensor has no effect then.

I thought SR is based on magnets, with coils interacting with the 
magnetic field to provide sensor movement.  That's how it doesn't use 
any power until actually functioning.  Does this model have a 
vertical/horizontal sensor?  That seems a more obvious candidate for 
unusual noise.

Yes, I can confirm that something of some mass moves inside the body

Likely to be the orientation sensor. IIRC it's a small tube with a ball
in it. The ball stays at one end and it's a horizontal shot, rolls to
the other and its a vertical shot. I can just about hear it in my
1DmarkII. You'll find it interesting when photographing looking straight
down or up. Like when doing repro work. If you handhold shooting
straight down, some shots will be horizontal and some will be vertical :-)

Don't even ask what happens if you take the camera into orbit.

This info comes from JohnCPentax, so it is about as official as you can

You guys are forgetting the permanent magnets that are also part of the 
system.  I don't think the sensor plate would move much, if at all, unless 
one of the electromagnets is turned on to make it do so.  When SR is off, 
wouldn't the potential movement of the sensor be a problem?

This is, of course, just me thinking out loud.  I'd love to see something 
more official on how the SR plate behaves when not in use.

Speaking of which, someone really needs to come up with an internet-friendly 
way of saying "thinking out loud," since we're all actually typing.  "Typing 
out loud" doesn't work, because on the internet, no one can hear you 
screa... er, type.

Also, "speaking of which" doesn't really work either, does it?

Yeah, in terms of the display, it senses vertical and corrects, I'm  
going to look into turning it off. You get half the image area, when  
it turns the display to a vertical. I'd rather look at it sideways or

Re: K10D - what's that rattle?

Yep, you're right. I just posted a retraction. 1
second is way too long to be effective with SR, it
would seem. But testing four shots back-to-back first
at .3 sec then at .7 sec the difference with SR ON was
huge vs. SR OFF(especially at .3 sec).

So, it's working alright.

Yea!

Re: K10D - what's that rattle?

[Paul Stenquist]

One second is way too much to ask for. Try shooting with a 50mm lens  
at 1/15th second with the SR on and off. You should see a difference.  
Unless, of course, You're as steady as I am:-)

Nevermind the above. Those shutter speeds are too long
for an effective test. I just compared shorter speeds
with SR on and off and it works great.

Re: K10D - what's that rattle?

I'm starting to think it's an inop. SR system. I can't
tell whether mine works. I have just been testing it
with long shutter speeds (1 second and longer) and it
doesn't seem to be working. The test shots are blurred
terribly.

The SR system was the first thing I thought of when I

Ah, ha!

Interesting. So you too have a "special" K10D.

Re: K10D - what's that rattle?

[P. J. Alling]

The SR system is based on electromagnets which aren't powered until the 
shutter is released.  Since there doesn't seem to be anything holding 
the sensor in place until then it probably flops around a bit, I can't 
think of anything that would stop it.

Re: K10D - what's that rattle?

[Juan Buhler]

I feel the same rattle. It's very subtle. It's not the battery or the
lens, and I don't have the grip.

I'm guessing that whatever the horizontal-vertical sensor is, is
what's rattling around.

BTW, by taking a landscape picture while accelerating the camera
horizontally, it is possible to make it think the picture was
vertical.

It's not a "rattle" per se, just a slight amount of
shifting inside the camera. SR on or off makes no
difference. Camera on/off makes no difference. I
thought at first it might be the battery moving
slightly, but that's not it.

No, I can't hear or feel anything like that. I don't have a battery

The SR shouldn't be moving at all when you rotate the camera: the magnets 
keep it in place.

If it sounds like a piece of something rattling around, I'd take it back to 
your retailer immediately for an exchange.

Of course, it could just be the ghost of the aperture simulator.

K10D - what's that rattle?

[Brendan MacRae]

Does anyone else have some internal shifting about
when turning your K10D from landscape to horizontal?

Mine has a slight "slip" that I can feel when I do
this. Very disconcerting. It doesn't seen to affect
anything so far. 

I was wondering if it has something to do with SR or
the dust removal system. Though this seems far
fetched.
