Hi All,

I believe that my camera is malfunctioning, but wanted to verify my finding with the forum before I send it off to Fuji Australia.

Since buying the camera I have been plagued with random glaring over-exposures. Being a novice, I assumed that this was due to user error, but after reading about this issue in other places I've come to the conclusion that my X100 is flawed.

To test this, I took a series of shots. Auto-ISO, Auto-DR, ND-filter, and flash were all turned off. The pictures were shot in aperture priority mode, with manual focus and no exposure compensation. I started at F2.0, and the exposure was correct.

For each successive shot, I narrowed the aperture by turning the aperture ring one stop. As you can see from the photos, this resulted in increasingly overexposed shots with the worst exposure at the narrowest aperture(F16).

It seems to me that my camera aperture is 'sticking' at F2.0 without narrowing to the selected setting.

Is this a case of user error or a broken camera? Is there a better way to test this? From the little theory I know, each of these shots should be at exactly the same exposure.

Thanks for your help,
Ash
