It's easy. Turn off face detection buy pressing the custom button. Set iris, shutter and exposure then turn on face detection.

Re: Auto Focus With Face Detection = Very Good

I thought my FS100 had also face detection and spot focus but I can't find it. So the EA50 has it and the FS100 not?

Re: Auto Focus With Face Detection = Very Good

I know what parfocal means. But one has to know both if the lens is parfocal and how to use it too. Not all lenses are parfocal and even if they are it is more difficult to focus at wide angle and expect the lens to be in focus at tele. That is why the recommended procedure is the reverse of that. Focus at tele and then frame for the field of view needed. Depth of field increases as one comes back from full tele position. A lot of modern cameras have electronic control of their parfocal performance and may not always be parfocal under all camera conditions. In other words the camera is refocusing what is really NOT a parfocal lens by itself but needs the camera to make it as such. True optically parfocal lenses tend to be really expensive.

Re: Auto Focus With Face Detection = Very Good

have to film carnival here with steadycam so I prefer The FS100 above the nex-ea50 quality wise.
About 1 month ago I filmed also a carnival with fs100 and stocklens on manual focus and peaking.

There were lots of shots not in focus. So I read about face detection about the EA50 here and thought my FS100 has it also.

I will just shoot autofocus this time because I have no face detection.
