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

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, p

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

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. On Sun, Nov 26, 2006 at 10:17:11AM -0800, Juan Buhler wrote: > I think you are confusing acceleration with ve

Re: K10D - what's that rattle?

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

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

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. j On 11/26/06, Jostein Øksne <[EMAIL PROTECTED]> wrote: > So panning will be an intere

Yes, I can confirm that something of some mass moves inside the body when you switch it from horizontal to vertical. But no problems so far, so I imagine is a normal part of the system. Angel Ramos Arecibo, Puerto Rico Brendan MacRae wrote: > Does anyone else have some internal shifting about >

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! -Brendan --- Paul

Re: K10D - what's that rattle?

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:-) Paul On Nov 25, 2006, at 10:33 PM, Brendan MacRae wrote: > I'm starting to think it's an inop. SR system. I

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. -Brendan --- Paul Stenquist <[EMAIL PROTECTED]> wrote: > Tried again.

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. Brendan MacRae wrote: > I hope not. It's not

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
