Confused about BBF
Dec 9, 2015 16:30:35 #
I shoot with a D7200. I have programmed it to BBF using the AE-L/AF-L button. By doing so, have I lost the ability to auto exposure lock? Like, green grass supposedly is 18% gray, how can I lock in my D7200 to meter off the green grass, then properly focus on my intended photo?

Can you program your fn button or another button to function as AE-Lock?

Perhaps so, Mac, I have not done anything the Fn button. Thanks!

ON a D7100, the front FN button can be set for many options, including AF-ON and AE lock.... I would think the D7200 has at least the same functions as the 7100.

I use BBF on a D7100. What I would do is focus on what you want in focus using the BBF (the release it), then you can lock your exposure on the grass with a half press of the shutter release. Reframe and shoot. In order to use the camera in this fashion, you have to set menu option C1 to ON (exposure lock with half press of shutter release). I normally shoot with this menu option OFF so that my camera will continually change exposure as I move the camera; but if I want to lock exposure, I have my front lower button set to a personalized menu with the C1 option right at the top for easy access. I believe the settings on the D7200 are identical.

The video by Back Country says to go to AF Activation under the auto focus menu. On my D600 there is no such option so I can't set up back button focus. What am I missing here? Am I brainless?

Don't you have a manual for your D600? If so, look on page 244.

Older Canon models (prior to the 40D) had the same problem... If you set up BBF, it used the AE Lock (*) button so you had no direct means of using AE Lock. Beginning with 40D and later models, Canon have two buttons... one for AF and one for AE Lock, so no problem. (Well, if you used a vertical/battery grip BG-E2/E2N with 40D or 50D you still had the problem during vertical shots, because that grip dates back to 20D and 30D and doesn't have two separate buttons. 60D, 7D, 5DII and later model grips all do.)
However, it really wasn't a big problem even on the earlier models. For one thing, with the type of shooting where BBF is most useful (action/sports/wildlife), you most likely wouldn't want AE Lock anyway. Just the opposite... AE "Unlocked" would be far more likely to be needed. But, if really needed for some reason, there was a different Custom Function setting that makes for AE Lock on ALL shots with half-press of the shutter release button. You just have to be careful to remember to disable AE Lock on all shots, when done using it.
Also, you still have Exposure Compensation, so can tweak the exposure as needed with that. Or, what I sometimes did instead was simply make a mental note of the exposure values, switch the camera to Manual exposure mode, then "lock" the shutter and aperture where I wanted them myself. That gives exactly the same effect as using AE Lock. (This assumes NOT using Auto ISO... which those older cameras didn't have, but would defeat the whole purpose.)

So we would have to name this Front Button Focus. :-) . I might try this, I think it may be more comfortable.

You can set the D7200 to lock the exposure with a half press of the shutter release if you like.

It took some doing, but I found my manual. Thanks for your help.
