Unsharp image when on tripod.

In 2016 I shot some images with the K-1 on tripod and with 12 s timer. SR automatically turned off. Horizon correction on.

I could not get a sharp image. Found help on the forum and turned on or off something but can´t remember what it was.

Anyone that remembers?

Recently the K3iii was implicated in some da shutter shock concerns that appear to be related to horizon correction being turned on. You might try turning that off.

I am trying to figure out if it is the same problem. The K-1 no longer has this problem.

I did not start a thread back then. Others had the issue so there were thread already. Not sure I posted...

Have searched without finding...

Are you shooting using the VF or using Liveview? If using liveview, switch off AF and do a manual focus using the magnifier (one of the best ways to critically focus on a tripod if the subject lends itself). It could be that you're using the electronic shutter which should be fine for stationary subjects but you should have that switched off if your scene has a lot of motion in it (it can create motion artifacts). If this gets you a sharp image, switch back to AF and use the VF to pinpoint your focus point and refocus and see if the focus changes - might be an issue with the AF system.

Not sure if my comment about the electronic shutter is applicable to a 12 second exposure but the horizon correction others have already mentioned could certainly be a cause as well, especially if it decides to change the horizon line during that 12 seconds (any noise in the system could make it do that).

The problem was fixed in firmware. I am trying to figure out if it is the same problem with the K-3 III

He mention using the 12 second self timer. I don’t think he said what the exposure duration was.

May be it is a movement of the tripod caused by the mirror. The 12s timer does not flip up the mirror when pressing the shutter release, but waits 12s and then flips up the mirror directly before the exposure. It's quite different from 2s timer, which flips up the mirror at once to calm down the swinging caused by the mirror.

12 second timer, not exposure. The exposure was a fast enough one.

No, it was something wrong in the software, you had to turn something off to make the problem go away. Now the problem is no more for K-1 since they fixed it in FW.

But K-3 III has a similar problem when using 2s timer and horizon compensation on. I wan´t to know if this was the problem K-1 had or if it was something else.

My bad. I read that wrong. In that case, the reference to the electronic shutter could still apply, however it sound's like something else since he said "sharp image".

Isn’t Shake Reduction supposed to be turned off if you use a tripod? Was it?

I think he is looking at a specific flaw with the K-3 III where if the horizon correction feature is on, the sensor is still moving during exposure when taken with both the 2 second and 12 second timers. This, regardless of whether the SR is on or off (normally it would be off in this situation, but you can force it on).

He remembers the K-1 having had a similar issue that was eventually fixed with a firmware update.

So we would hope the horizon correction problem with the K-3iii will also be fixed in a firmware update like it was for the K-1. But is it too much to hope there will be a reviewer firmware update? Oh well...

But why would you use automatic horizon correction on a tripod while you have all the time of the world to adjust you're ball head so the camera itself is horizontal ????
I think this function is totally useless when using a tripod. (or am i missing something?)
