Just a couple of personal thoughts on Back Button Focus<\/strong>. I’m surprised at the number of people who don’t use this tool – it allows you to have a lot more control over what the camera is doing…<\/p>\n\n\n\n

This is a NIKON mirrorless camera (but many NIKON cameras are similar) – and at the top right is a little button marked AF-ON. When you receive the camera, the default setting for the AF activation is the shutter button. To reassign this to the AF-ON<\/strong> button, go to the Custom Setting Menu<\/strong> and scroll down to a7 AF Activation<\/strong>.<\/p>\n\n\n\n

a7 AF Activation Menu<\/em><\/p>\n\n\n\n

Now you can select AF-ON<\/strong> only<\/strong> which will decouple the AF activation from the shutter button and assign it to the AF-ON<\/strong> button instead. Once you have scrolled to AF-ON only<\/strong>, click on the right arrow button which will display the Out-of-focus<\/strong> release menu. Select Enable<\/strong><\/p>\n\n\n\n

This allows the camera to make a picture even if the subject isn’t perfectly sharp.<\/em><\/p>\n\n\n\n

Now all this actually gives you a lot more than just moving buttons.<\/p>\n\n\n\n

1 : A first pressure on the shutter button will now lock the exposure setting.<\/p>\n\n\n\n

2 : If the camera is setup correctly, with the Focus Mode <\/strong>(Photo Shooting Menu) set to AF-C<\/strong> Continuous AF, you will be able to control BOTH<\/strong> the exposure AND<\/strong> the autofocus at the same time, but independently.<\/p>\n\n\n\n

Think of the flexibility – you can lock (or not) the exposure while independently controlling what the AF is doing – this is even more important when using the 3D AF tracking functions. <\/p>\n\n\n\n

This takes a bit of getting used to, but everyone I’ve spoken to that has adopted this system are firmly convinced it’s the only way to go!<\/p>\n","protected":false},"excerpt":{"rendered":"
