Z2 unstable video exposure

[davidy]

I bought the Z2 for it's video camera capabilities I'm very surprised to find that there is no AE or AF lock on the Z2 for video. In video mode the camera is almost un-usable because the AF and the AE hunts around like crazy even in decent light. see https://www.youtube.com/watch?v=sY82RvW69Wc Local Sony tech said that this maybe a faulty software design. I'm hoping the updated software supplied with the Xperia Z4 makes it's way to the Z2.

Just for other users that might read this and don't quite understand. 

• AE-Lock. AE simply stands for automatic exposure. The button allows users to lock their exposure settings (i.e. aperture and shutter speed). AE-lock can be extremely useful in many situations. For example, if a photographer is taking a series of images for a panoramic photograph and needs identical exposures, such as if you want to stitch together a set of photos to create a panoramic photo, AE-lock can allow you to be certain each photo has the same exposure. AE-lock can also be very useful in difficult lighting situations.

• AF-Lock. AF stands for autofocus, and AF-lock is the easiest of these lock functions to use. It's also the only one of the three that happens automatically when you take any photo. AF-lock is activated by pressing the shutter button halfway. By keeping your finger on the shutter button as it's pressed halfway, focus is locked. This can be very useful if you want to focus on a subject that is on one side of an image. You can lock the focus on the subject, and then re-compose the image without taking your finger off the shutter button.
