645Z Aperture Problem

My Z has developed a problem. The aperture will randomly change after taking a picture. For example, when shooting in manual, if the aperture was set to 11, it might randomly shift to f10 or f13 without my making a change for the next shot. It has been doing this for the last few outings.

Is this a known problem with the Z? I really hate the idea of sending it in for repair for a problem like this, especially since I bought it in Canada and not the US.

If you have instant review on, the e-dials still affect the shutter speed and aperture. Is that throwing you off perhaps?

Thanks for the reply. I will check my settings to see if that is the problem.

I experience this problem when I try to zoom in to the instant review pic before it is displayed where you can zoom in, usually after a series of shots. Instead of zooming in (with the dial) it changes the aperture 1/3 stop instead.

The explanation given above is probably it, but just one silly thing to exclude - you don't have the camera set to auto bracket do you?

No, I don't have it set to auto bracket. I do use the 2 sec delay when on tripod. In general I don't purposely use the multitude of settings available in the camera and have a lot to learn about them, just shoot in manual.

Later when I have a chance I'll experiment with settings.

I've not been able to figure what was going on. Today first off the problem was there. The battery was low and after changing the battery the aperture shifts have not been reoccurring.

From the responses from the forum I conclude that this is not a common problem.

Also make sure you're running the latest firmware. A number of goofy glitches in the Z have been fixed over the months.
