weird metering thing going on
Hi guys,.

Ive recently bought a sony a100, and am new to photography. My camera is doing something quite strange..

Basically it looks like it's doing some weird automatic metering kind of thing..

Here are some sypmtoms -.

Left dial (ISO etc) does not respond. - when pressing the Fn button nothing happens.

Menu button and the three underneath that do not respond..

The main symptom is that the exposure number on the display keeps moving automatically ie from 0"4 up to 20 whenever you move the camera. If you keep it still it settles down. this is what makes me think that it is some kind of metering option that ive turned on without knowing..

Please can ANYONE help! I cant use it at the minute..

PS ive taken it to jessops and they didnt have a clue..

Cheers guys.

Maca..

I don't know the camera, but my first guess is take it off automatic and see what it does. Set it to Aperture Priority and see if you can control things..

Nothing is enough for the man to whom nothing is enough...

Just thought of another one. Take the battery out for 30 seconds and then put it back in..

OK, sounds like you need to read the manual.

First find out what this thing you call "exposure number" really is (shutter speed?? aperture??.

What mode are you using manual/m??...aperture priority/a?? shutter priority/s???.

(figures on the right hand dial).

At a guess, id say your in aperture priority/a mode and the number is showing how the shutter speed changes automaticly as you point at lighter/darker areas.

Or they could be aperture numbers and your in shutter priority/s mode.

Learn what these modes do.

Sorry I cant advise on the function dial operation, it is a sony specific thing.

Maybe re-post on sony forum for this..

Because you have unresponsive controls, it sounds as if the camera is continuously and actively performing some ongoing function apparently that being metering. It is doing this instead of just 'idling' whilst it "waits" for you to instruct it, and that is not right..

This suggests to me that some switch or other has stuck in the 'ON' position, and this is keeping the operating system fully occupied..

Sorry. It just isn't possible to guess which switch it might be that's causing it. It could be any of them ... or even more than one, if you are terribly unlucky. .

It could even be a "soft" switch that has stuck, one that has existence ONLY in the firmware (operating system)..

Assuming that I'm right about this (!)..... My suggestion is to press ALL the hardware that buttons you have.. repeatedly and vigorously.. to see if you can get whichever it is to UN-stick itself.... at which point you may be able to reset the camera with a cold boot and take it from there..

On the other hand, if it is just a firmware thing (it can happen it's called a glitch!) the cold boot procedure itself is your best bet for clearing it yourself..

Otherwise... it sounds like a repair job to me... (shrugs).

.....which is a drag, so I sincerely hope that is NOT the case.Regards,Baz..

I tend to agree w/ Alethesia. If you're in an auto mode, you may be limited in what you can control. The numbers you mentioned sound like shutter speeds that the camera might be setting based on the situation (though they are somewhat high)..

You may want to review your manual again, and if you still have trouble, try the Sony SLR forum here. You'll have a better chance of finding someone more familiar with your camera..
