"Using custom setting C1, shutter-release button ae-l"


US
          

Hi all, I am using back button focusing on my d7100 and just noticed the custom option (pg 236 in the manual) which seems to make it possible to just half-press the shutter button once to lock in exposure. So seems to me that, shooting a sunset for example, you could read your exposure setting from a more neutral tone in the sky by half=pressing the shutter button once, then recompose on a brighter part of the scene without keeping your finger on the shutter button the whole time. Do I have that right? And has anyone used the option in combination with back button focusing?

Not exactly. You would have to keep the button half-pressed. Turning C1 on means that when you half-press, the camera meters the exposure and locks it in until you release the button.

And yes, it is useful in conjunction with back-button focusing.

Wow, that's important info. So at the risk of appearing as ignorant as I really am, what goes on if C1 is NOT on?

Exposure doesn't lock when you half press. The meter keeps taking readings until you release the shutter (fully depress the shutter button) or take your finger off the button.

So what is C1 turning off and on?

The C1 setting is determining whether or not the exposure changes as you hold down the shutter button and recompose.

Really, the best way to understand this is to try it. With C1 On, frame a bright area, recompose to a darker area while holding the button, then fully depress the button to take the shot. Do the same thing again with C1 Off. The difference will become apparent.
