Startup Sensor Shake
Over the weekend, I shot extensively at several events, and I noticed something. It seems that the shaking process at startup that is supposed to clear any dust is sometimes lasting longer, usually more pronounced (louder and you can feel the vibrations are stronger), sometimes also slightly delayed.
There seem to be no problems, and even after I did some cleaning once I got home, the varied performance on startup, compared to what has happened in the past, is continuing. Has anyone else experienced anything like this? Is this just a natural response to sensing what may still be some stray dust floating around, or an indicator that problems may be coming?
(Should have mentioned that.)
My nervous nature made me wonder if the camera is trying to tell be something, or if it is just trying to do its job.
I'm not sure that it cleans the mirror when you turn it on. Mine makes this like hmmmm like very short digital sound like somethings moving about 1/2 a cm. It's more high pitched.... really hard to describe.
The shutter sounds normal and takes pictures fine though?
I think the sensor clean and dust shake are automated at start up. I do NOT think they can tell if dust or dirt is on the mirror or sensor and compensate for it. It may recycle itself and rerun the shake if it is picking up something? You may want to also check online foe info. or go to Sont support, I understand that can be more annoying then the problem you are trying to check on LOL! Just a guess here on my part.
Shutter is fine
And it shoots the same as always. Perhaps Mr. Don can better explain the workings of the sensor "cleaning" shake?
I am pretty sure the cleaning shake occurs when turning the camera off, not on. Don had some input on it here:
