istDS sensor tilted?

2006-01-29 Thread Ralf R. Radermacher
It appears the sensor in my *istDS is tilted by about 1 degree. May not sound like much but actually is a whole lot with industry and architecture. Has anyone else had this problem with a Pentax DSLR? Ralf -- Ralf R. Radermacher - DL9KCG - Köln/Cologne, Germany private homepage: http://www.

I haven't seen any evidence of misalignment on either of my D cameras. What makes you think your sensor is misaligned? I would think that an accurate test is very difficult to perform in that it requires precise alignment of a camera and target. On Jan 29, 2006, at 8:37 AM, Ralf R. Radermacher

Of course the camera has to be more than leveled. The lens mount has to be squared off exactly to the target. On Jan 29, 2006, at 9:51 AM, David Savage wrote: Level the camera on a tripod and take a test shot that contains horizontal & vertical lines & check to see if the results are wonky? Da

Hmmm. Then the misalignment could be either in the sensor or the viewfinder. On Jan 29, 2006, at 10:39 AM, Ralf R. Radermacher wrote: Paul Stenquist <[EMAIL PROTECTED]> wrote: What makes you think your sensor is misaligned? While everything is nice and level in the viewfinder the resulting

Reality is the reference. So both could be misaligned with reality, yet aligned with each other. Or all three can disagree, which is the worst case because you have to align both the sensor and the viewfinder. Bob Shell wrote: On Jan 29, 2006, at 11:33 AM, Paul Stenquist wrote: Hmmm. Then

You have to test for both a tilted sensor and a tilted viewfinder. first find out if your viewfinder is tilted. You have to use a reference. Since the ultimate reference is reality, and you have to be able to trust your tripod and the relationship of the tripod to the camera, I would suggest

Well, I went off and followed my own procedure. Here is what I discovered with my *istD: * The viewfinder is not aligned with the camera base. It tilts to the right, so it has a significant negative angle. * I took the picture, but it was not very useful, since the viewfinder was already m
