Another question about back button focus.
Jun 23, 2018 09:26:43 #
A post about BBF on the Nikon D7200 this morning prompted me to ask another question. I have a D5600 and have downloaded Steve Perry's ebook (so glad I did!). Following his instructions, I set my camera for BBF and am still practicing, but I think I will like using it. My question: Is there any situation in which BBF is not recommended/useful?

Not that I know of and I have been using it for years.

If you forget to to use it you may have out of focus images. it takes a while for it to sink in.

I think that if you use a cable release (remote) it won't focus when you press the button.

Macro, I would think. I assign it to one of my "U" selections on my D7000 so I can switch back and forth.

At least on my Nikons pushing the button half way down activates the focus and all the way down fires the shutter on the remote just like on the camera.

But he's using BBF. "Normally", I think, you (I) would disable the shutter release button from focusing when using BBF.

Yeah, I think with a remote you don't have access to the BBF button, but then you probably have the camera stationary on a tripod so I don't really see any advantage with using the BBF feature in that case.

Exactly the other way as you said, when using BBF on tripod, you can focus on the object that you want it to be the main thing in focus but you want it in some other area of the frame other than center, it means focusing the object first and turn the camera to re-frame or re-composition, then take the picture. This can be applied hand held with the camera too by moving the focus point in the viewfinder to the object you want to focus when re -composition.

With some of the Nikon cameras there are 4 different shooting menus. I use BBF for BIF but for landscape I use the shutter release for focusing.

How is the exposure affected when you do this?

If you are going to use BBF use it all the time. If you use half-press of the shutter button use it all the time. Just my two cents worth.

Exposure in this case is an other thing, If I want the main object in focus and it with right exposure, I can lock in the exposure with the button (AE/AF) when focusing with the (A/F-ON), (my Df has both button). If your camera only has one (AE/AF) that you have already assigned it to BB, then you can still using the old way (Press the shutter half way to lock the exposure.

Its not much use when you are set to Manual Focus!! No, I am not being sarcastic. I recently switched to BBF too. A couple of my lenses have MF/AF switches on the lens. When BBF wouldn't work I was in a state of panic thinking my camera was busted until I realized it was on MF on the lens. The AF/MF - AEL switch on my A7Rii gets me confused too. I don't have BBF assigned on my A6000. I find myself looking for it when I use the A6000 even though I use the A6000 nearly as much as the A7Rii
I'll figure it out eventually. Once BBF, you will never go back.
