Jurgen,
I recently purchased the A75 on 24 June, and I loved it. Three days ago the flash stopped working. I wrote an e-mail to their support, and was informed that I would have to have it serviced. I took it back to where I bought it from and they replaced it. That said, I love that camera. I have no idea of whether it was bad luck or what, but I really like the camera. I hope this one lasts longer than 2 weeks!!!!
Ciao for now
Rob
