BBF and AEL: I switched my D7200 to Back Button Focusing about 2 months ago and I'm not going back. It seems one of the trade offs is the Auto-Exposure Lock doesn't work with BBF...

I switched my D7200 to Back Button Focusing about 2 months ago and I'm not going back. It seems one of the trade offs is the Auto-Exposure Lock doesn't work with BBF configuration. Is there a work-around?

I also notice in BBF, that when I push the shutter release half way, I hear the servo. The focus plane doesn't change, but I do hear a sound. Is that normal?

TIA,
KC

Shooting in manual will get around the AEL problem. Not sure about the motor running...

Set it so half press on release is your exposure lock... with BBF (which I use) if it's tracking you may hear the servo. I don't hear it on mine, but then I wasn't listening for it either.

Yup, I shoot in M quite a bit, but where I miss it, is when I shoot in A or S and want to Spot meter away from the center. Not a big deal, but I miss AEL.

I figured out the servo activating. User error. I had different settings for AF-C and AF-S for the Shutter Release.

Thanks OnDSnap. That's exactly what I want to do, but I haven't been able find that option on the D7200.

You may assign the other button for AEL, if your d7200 has the Pv or Fn, that can be assigned for AEL. Check your custom manual setting "f"(control).

The servo that you're hearing at half-press is probably the VR in the lens activating, at least that's how it works on my D7000.

I have mine set up, that the shutter button becomes the AEL button, so it works just fine with BBF ( I shoot Canon).

KC...I think I miss read your post, after re-reading your post and knowing what you want to do, shooting manual is (as mentioned) how I do it...you can set the release button to lock exposure using "c1" set to on, however while the AF/AE is set to AF On (BBF) when you press to lock the exposure with the shutter button, it seems to uncouple the BBF temporarily till you release the shutter button. I don't think you can have both :( Unless a combination of other settings may achieve it. Sorry for misleading info.

I'm correcting my self...c1 =ON (locks exposure with shutter release half press) f4=AE-L/AF-L=AF-ON (BBF) So it can be done...
