Advanced Camera Settings for the A9 and A7RIII cameras

A7RIII and A9 Custom Settings

The release of the A9 and A7RIII cameras has heralded some powerful new custom settings to be found in the menus. Some of these options, however, may not be obvious to implement from reading the camera manual. With this in mind, I have made three movies to cover the following three menu items.

  • Swt. V/H AF Area
  • Reg Cust Shoot Set
  • AF Area Regist.

If you are tired of moving your off-centre focus point every time you switch between a Vertical and Horizontal framing of your subject this option will make the process much more fluid.

The option to register an AF point or AF area, that can be recalled by simply pressing a custom key, is a great new feature. Changing AF area has previously been a two-step process (first selecting the AF area menu and then the AF Area). This can now be fast-tracked into a single press of a custom button. I personally use this to swiftly change from ‘Lock-on AF: Expand Variable Spot’ to ‘Lock-on AF: Wide’ when the subject I am trying to track becomes to erratic to nail with the variable spot.

This new custom setting would appear to duplicate the Memory option – the one where you can register a group of camera settings and then recall them by selecting 1, 2 or 3 from the Shooting Mode Dial on the top of the camera. This new custom setting, however, allows you to swiftly change to a group of settings by simply holding down a custom button and when you let go of the custom button you instantly change back to your previous settings. One of the primary advantages of this for A9 users is that you can register AF Mode and Drive Mode to these Registered Custom Settings which is not possible when using the older Memory menu (due to the hard dials on the top left of the A9 camera). As I do not use the AF-ON button for back-button AF I can now supercharge it to recall Shutter Priority with a 1/2000 second shutter speed, Auto ISO, AF-C, Lock-On AF: Wide + AF-ON.


When the A7RIII camera is set to Continuous Shooting Hi using the mechanical shutter. it behaves more like a full-frame A6500 rather than a slower A9. This movie runs through the optimum settings for capturing and freezing pin-sharp fast-moving subjects.

    One question please.
    I’ve been enjoying the Sony a9 + 100-400GM + 2.0TC but am curious about how you would set this kit up for fast action/BIF.
    So far I’ve been using the combo in Manual with auto-iso but I see you prefer Aperture Priority.
    Would you still shoot Aperture Priority with Auto-ISO and Min. Shutter speed of 1/1000-1/2000 even with the F11 imposed by the teleconverter+zoom combo?
    Thanks. Robert
    p.s. almost all the eagles (one was via RX10iv), in this album were imaged with the a9+100-400GM+2.0TC, just amazing that a camera can AF-C track at F11
