There are eight focus area selections in Sony A7R.
- Wide: the whole screen is active, so the subject can be anywhere. The camera determines focus by picking the object that is either closest to the camera, in the center of the frame, or a face if there is one resent. Focuses automatically on a subject in all ranges of the image. When you press the shutter button halfway down in still image shooting mode, a green frame is displayed around the area that is in focus.
Wide could be used in situations where your subject is by itself like portraits of one person or product photography. It is not recommend to use for multiple subjects or objects in the frame. - Zone: With Zone area selected, you can now select a large chunk of the frame to focus on, but the camera will still help select focus in that area. There are 9 different areas or zones, so you can have more control over where to focus. The Zone is good because you don’t have to move the spot around a lot, but it’s bad in that you still don’t have complete control.
- Center: The Center Focus Area leaves the focus point in the middle of the frame, and that’s about it. You just have to put your subject matter in the center, and you will get it in focus.
- Flexible Spot: you have a dot or square that you move around the screen and put on your focus point. With Flexible Spot, you control exactly where the focus goes.
- Expand Flexible Spot: takes Flexible Spot M, but it allows the camera to try to help. When you’ve got your focus point on your subject, the Expand Flexible Spot will “expand” if needed outside of the focus point to grab focus.
- Lock-On AF Expand Flexible Spot: This focus area takes Expand flexible spot, but then it will lock-on and follow the subject once you have started focusing. It could be used for tracing birds and sport objects.
- It does what Lock-On AF Expand Flexible Spot does but in a different way. The first big difference is you have to activate this every time. You have to turn it on, put the subject in the center of the frame, and then select it. This makes it more involved than Lock-On AF Expand Flexible Spot. The other big difference is the way it works. Once you choose the subject, you don’t have to hold down the focus button. The camera just keeps following that subject.
- Eye AF Eye AF goes even further into autofocus and face detection and will automatically find a subject’s eye, focus on it, and follow it!
To select focus area, go to MENU → (Camera Settings) → [Focus Area] → desired setting. Or press Fn.
