I can only confirm that at least the first generation model is totally unreliable.
As others described often enough the camera would just turn off mid shooting, with only the first half of the shutter sound (shutter count 32k).

Sony insists on charging you for replacing the Shutter unit, which will likely die again within the next 15-50k.

Design flaws can happen, but Sony Customer Service is just terrible. Definitely not going to buy into their systems.

It seems Sony A55 is very unreliable camera.

While I was taking photos, camera suddenly went black Fully dead. I verified battery is 100% charged.

I tried to contact the repair centre and no feed back. I am very much frustrated as my friend who took Cannon at the same time with me has had no issues with his and I have many other friends ho use Nikon never had issues with their cameras. I feel sorry for my decision to go for SONY DSLR.

I think that the fixed mirror means the cameras are relatively small -- 23 per cent smaller and 26 per cent lighter than the Sony Alpha DSLR-A550, to be precise. They're very light, but with a solid and comfortable rubberised grip.

It does, or rather, did. Strangely, Sony decided, presumably for sound commercial reasons, to delete this body shape when they released the current model, the A58, which is bigger than the A55, 33, 35, and 37 which were all this shape. I like my cameras small (as well as light) so this shape definitely interests me more than the A58.

I love it. It is easy to use and I have never had any mechanical issues with it. I especially love the rapid shooting feature. My grandchildren never stay steady for a second. With this feature, I can go back and delete the frames I don't like. I also used it at professional sporting events at a great distance using the zoom lense with great success. I've also used the portrait function for stills. Great camera!

I have not had a good time with this camera. Just over a year after buying it the camera stopped working and SONY charged me £117 for the repair. Now just 7 months later the camera has a different fault and will not focus or take photos. Sony want a further £117 for repairs!! I feel this is not what i expected from a camera at this price and SONY are not interested in the fact that possibly I have a poor quality camera. I would NEVER recommend a Sony camera to anyone

hey, sorry for your bad luck. Sony manufactures good, but sometimes quite unreliable cameras, I agree.
