I found this on another site. I did not check out all the links. Take it for what it is worth.

I was thinking hard and long before posting this as I don't want to kill any enthusiasm that has developped on this forum re the A77.
Apparently the current batch of A77s has/can/might develop some issues that have to be solved by Sony. So if I were in your position I might want to hold back with running out and ordering one as you might end up having to return it or wait for a bug fix.

Now please take note I said "might"! The strange thing is that these bugs did NOT happen when reviewers reviewed the A77!

Here are some links that are off some concern:

It sounds like Sony will have two cameras to fix, the Sony NEX-5n and now the Sony A77 too!

Well what happened is I was playing with my new toy when suddenly it stopped working, then I switched it on and since then I'm able to see only black screen or go to the menu, where I can't change anything. Tried everything, taking off battery, connecting to pc ( couldn't do even that)


And there are many more

So far nobody seems to be sure whether this is a hardware problem or a firmware issue!

Please I really do not want to kill your enthusiasm and as said, some people do NOT have these problems, but you might want to check!
