I switched a few years ago and have never looked back! Even on my battery grips :) It has now become a second nature :)

I discovered BBF just after buying my first DSLR (40D) a few years back. It's the only good way to shoot moving subjects, IMO. It makes it so much easier to keep focus and wait for just the right moment to release the shutter.

so when enabled, do you have to keep it held down to track? if you want to lock just push the button once and then release it?

i think i'm going to have to check the ergonomics when i get the a6000 as it does sound too good to be true.

You have to hold it down. The nice thing is if something enters the frame say between you and the subject you are tracking you can let go of the button let the subject pass by than focus back on your subject with minimal auto focus delay seeing focus didn't grab the closer subject that just passed through the frame and still maintain IS. and exposure.

hypothetical situation;

shooting a car at a race track.... back button focus onto it, hold button in, click shutter - car moves from bright section of track to dark section, you can release shutter and click again for new exposure without loosing focus lock?

ok, so perhaps model in high dynamic scene, back button focus on model's eye, re-compose and shoot with correct exposure for whole scene??

To simplify, when you change button functionality using the custom function menu. The shutter button can be set to do three specific functions 1-focus,meter 2-meter only 3-AE lock. Back button can be also set to do four functions 1-meter/auto focus 2-AE lock 3-AF off 4-FEL.

once you go Back button you never go back. Its also funny to watch someone use your camera and not be able to get it to focus :)
