View Full Version : FX1 iris 'flicker' - pulsing brightness levels+

I've recently noticed a problem with my FX1. It has started exhibiting some sort of brightness flicker where the picture will darken slightly for a split second, almost if the iris is closing and opening rapidly. At its worst, the flicker 'pulse' happens once or twice a second. It is visible in the LCD, in the viewfinder and in captured video on the computer.

The problem is intermittent, and has happened in all types of scenes, broad daylight, dusk, indoors, etc.

The flicker happens on full manual with the iris and gain locked as well as on all-auto. No filters or anything on front. I'll post a clip here shortly. I am really hoping this was some setting that I inadvertently changed recently. I've had the camera since October and it has just started doing this last week.

Most of the time it is barely noticable, but occasionally it is noticable enough to ruin the video.

If it is on full manual, and that means everything, then it needs repair.

Timing couldn't be worse. I'm leaving May 4 for a 3-week project, one of the main projects I purchased the camera for. Is there a place that can do warranty repairs in 2 weeks?

I have no idea. Sorry.

I was wondering if anyone else had this problem and how common it is.

No one else has ever had this problem?

No, nothing like that at all...

Just a quick update to this thread. I shipped my camera to Sony's Laredo, Texas repair center last week. They received it on Friday, October 27.

Sony has finished the repair as of Wednesday, November 1 and the camera is already en route back to me. I was charged the standard $249 labor fee (the camera is still under the one-year parts warranty).

They replaced over $800 in parts, including the lens, to address the 'iris flicker' problem. I should receive the camera either Friday or Monday, at which point I'll update again after testing things out. If all is well then, I'll be very impressed by the Sony warranty repair process - about a 1 week turnaround time from start to finish.

That's good to hear, Dan, that Sony is pretty quick about repairs. I'm going to be shipping mine to them soon due to a weird, pulsating, popping noise from the speaker.
