Sony handy-cam DCR-SX85 question?
Go find the Manual that came with your Camcorder. In that, look for the section that tells you how to shoot in Manual Mode. Doing this this shuts of the Auto focus function of your Camcorder. All good Video Shooters know that and use that.
No, it can't. You've asked about firewire in your other question - firewire's just another PC interface, like USB. The difference is that it supports a data transfer mode that guarantees the availability of enough bandwidth to do video transfers in realtime. USB2 is slightly quicker, but it can be interrupted, which is bad news if your camcorder's still trying to send data down the wire from its tape. Firewire also allows the camcorder to be controlled from the PC, which can't be done with USB.
Low light situations will typically make any auto focus system go crazy. Check the sensor area in the front of the camera and be sure it's clean and free of any dirt, that may also cause the auto focus to act up. The camera has manual focus option which you can use to lock in focus. But you can also try changing the focus 'Area' this camera features an option for 'full range focus' or 'spot focus' See if changing this auto focus option helps. Turn off face detection as well, this can sometime cause the auto focus to act up. Also, turn off image stabilization hat can cause less sharp video Researching other test samples from the DCR-SX85, it looks like blurry images are a common issue. If it's not too late, it may be worth returning/exchanging the camera for something else if you are still having issues.
