I have the camera sitting next to another A700, both with the Sony 16-50 2.8 SSM attached.   Both dials are set on Auto. All other settings the same. The working camera chooses 1/30 2.8 and takes a normal photo. The other camera chooses 1/1000 f9 and takes a black photo. The setup is indoors with dim lighting. If I point the faulty camera outside directly into the sun, it chooses the same settings. the photo is much better, but still too dark.

If you set the "Bad" camera to "M" and take a photo at 1/30 2.8; what do you get?
Is the AEL button functioning freely and correctly (not stuck)?
In cleaning mode "Menu" "wrench" "3" fourth down (mirror lock up); look at the sensor with a flash light. What colour is it?


Both camera sensors appear the same greenish color and look clean. AEL button seems normal.

and on manual, metered externally? No changes from Multi-segment, Center-Weighted, and Spot? No "frost" or haze on the sensor?

Nope, no changes when I select between the choices.

Sensor looks normal.

I’ve not tried any external metering
Only from the mind of Macronut.

Well, short of the manual settings experiment, which will expose a sensor fault or software; I would put the blame, as a best guess, on a firmware installation interruption.

I think I might agree. V4 is still available for download, might be worth trying a re-install of it.

When I get the time, I’ll try that and report back. Thanks everyone!
