I've bought an Sony A55 camera for home use. Recording video is very important for me. Fortunately this camera is very good in video recording. It records 1080 HD and more important than that it does have autofocus during the video recording. If I ignore sound of lens moves for autofocusing there is another problem that I can't ignore with this camera autofocusing. It gets too hot and stops recording video after 5 to 10 minutes then shows an alert saying "camera is overheat, let the camera cools down". This is a known issue. Sony recommend to turn the autofocus off.
So this camera couldn't be my choice, I want a camera with great video recording capabilities. I have to return the camera then. But before that, I want to know what should I buy after I returned this camera? What is the best DSLR photo-camera for recording videos. I want autofocusing while video recording. Please don't recommend me buying a video camera. I don't want to do that.
When I was very happy with the camera I posted this video to Youtube to show off the focusing future!
I also found Canon's autofocusing EOS 5D Mark II too noisy and also out of my price range!
