    Posted: 21 April 2011 at 15:11
My a550 is showing the same problem I used to get with my old Minolta 5D. When the camera is swithced on, the first photo taken in that session will be recorded as a black frame. Everything taken in the same session will be fine. Whereas my 5D used to do this only when it had been switched off for more than 24hrs, on Monday my Sony did it within a 10 minute switched off period. The camera is about 3 months out of warranty but as this seems to be an issue that is becoming more apparent with other users, I wonder if Sony will do a free repair like Minolta did. Has anyone else had the same issue with Sony's latest batch?

If its out-of-warranty, you probably wont get free repair. But you may try to suggest (be mean if you need to) that its manufacturing defect, which it is.

Though, Im bit suprised, that they didnt fix it during those 6 yrs. :D

My a550 has the same problem. I just learned to live with it. Always waste the first shot after turning it on. And it doesn't always do it, but usually does. It is now my backup camera to a a580, so it's not as relevant. Still annoying, however.

I'm really surprised to read this...

For 5D/7D, it was not just an exceptionally occuring error, but a simple design default.
I can hardly imagine Sony would make the same mistake as Minolta after fixing this bug first .

IIRC, the a450/500/550 will take a black frame to map out hot pixels every once in a while when the camera is restarted. are you sure this isn't what's happening?

At least on earlier models, that would happen when the date changed to a new month, but it happened during start-up, not on the first shot.

If you trawl around the forums this issue pretty much affects a small proportion of all Sony APS-c cameras.

My A350 does it, and I have seen reports of it doing it on A300/A450/A500/A550.   However Sony is somewhat reluctant to take it on as an issue as many folks had/have trouble convincing Sony that this is a problem. Symptoms are generally first frame grossly underexposed but all EXIF looks correct. It normally takes about 24hrs to repeat, becoming much more pronounced on high shutter speeds.

However, the good news is that I have not seen any reports indicating that this behavior is terminal for the camera, however if it regularly FFBs every 10mins then that is pretty dire.

I think what you mean is that Sony probably know about it, but don't want to accept that it is an issue which requires them to provide support outside warranty (rather like the A700 control wheel issues).

The best recourse, in the EU at least, is to go back to the dealer your bought it from - under law they generally have a greater requirement to deal with "unsatisfactory" goods than Sony may think they do.
