How to lock exposure when using back button focus (Page 2): Gene51's suggestion is on point -- read the manual. I keep a copy of my manuals on my iPad and I refer to them all the time...

Gene51's suggestion is on point -- read the manual. I keep a copy of my manuals on my iPad and I refer to them all the time for things I forget or when I run into quirky situations. P.S. I'm a tremendous fan of BBF!

Clearly I can press the AE lock button (BBF) and then recompose and shot. How about metering and recomposing the shot? I mean, I'm using the AE lock button for focus.... how may I lock exposure?

Oh geez!

Since you took that button feature away when you assigned it for rear button focus you need to assign another button on your camera for AE lock. Your camera manual will take you through the steps, it is not hard.

I'm still unsure of what you mean , but as for locking exposer ,as soon as you take your finger of BBF the exposer is locked , it is locked there tell you push it again .it will stay there all year locked , and if your taking pictures every day your going to get a lot of messed up shots if you never refocus for the changes in distance,

All the advice regarding BBF and reassigning the exposure lock to f2 button is right on. But allow me to complicate the issue one step more...I shoot stage (mostly ballet) and because lighting varies from scene to scene, I also use Auto Iso. Question is wil the f2 exposure lock setting hold when recomposing; the scene lighting has not changed but the spot focus area has changed due to recomposing the shot?

Forget about exposer lock, it's locked once you take your finger of the bb which you have a asigned the job of focus, it not like using the shutter button if you keep pushing it locks and takes the picture, just put your camera on continues focus never mind locking anything , happy bird hunting ,

I suppose I could reassign the preview button

That would be the beast idea. Either the fn button or the preview button. I have set the fn button on my D7200 to AE-Lock (Hold).

Read the manual, this is not the case. Focus actuation is separate from exposure unless you have specifically set the camera to do that. Camera default is exposure is on the shutter button on half press. If you move the focus activation to a different button, the exposure lock is still on the shutter.

Read the manual. This is not how it works.

I just shoot the big "M" for manual mode.

IBM, you clearly don't know what you're talking about and are just guessing. Do you even have a Nikon? Read the manual if you have one, if not, the pdf manual is online at Nikon USA.

I have the 750 and use back button focus, and often expose by half pressing the shutter, then I can recompose to the shot I want with the locked exposure. Play around in the house and you will see it's simple.

I have read the manual, I just got a little confused, that's all. I'm just learning and it's not like there are only a few features on this device. Doing the best I can.

Might someone respond to my question about using auto-iso with a f2 button exposure lock pressed but not held. Does the exposure stay locked or does auto-iso overide the lock when the spot focus/exposure point is moved when reframing the shot? I've played with this (yes I'm shooting M) and can not tell if the exposure changes

look in the viewfinder as you move the camera. Are the numbers changing?

Yes I have two of them, there both set on BBF for the last three or four years and never taken of that mode and I don't imagine they ever will be it's so much easer than tickling the shutter the other way , and I get a lot more keepers, instead of missing shots, it's not rocket science but to most people it appears to be just that , I really can't get over it ,
