Another question about back button focus.
Jun 24, 2018 10:15:30 #
If you ever give your camera to someone else to take a photograph, e.g. you with Machu Picchu in the background, make sure you tell them specifically what button to press to focus. Instinctively, they'll think the shutter button will do the focusing. I've had a few blurred shots of my wife and me because I forgot to mention this.

It seems to me that with BBF you are using two fingers to accomplish what one finger can do.
True but... With BBF the focusing never stops. When you press the shutter, the photo is taken and the camera must re-focus.

Actually if nothing moves (you, the subject) the lens) you are still focused.

I do the same thing sometimes. However, there are times.. like shooting from a tripod at a semi-moving object.. waves.. boats or whatever that I want the camera to focus on the moving object. So I have my U2 set for autofocus before shooting. Since it is U2, it doesn't get implemented or used unless I select it and it eliminates guessing or the "awww shucks, the subject moved" incidents.
I had done something similar when I had the D7100, but that option is not available on my D500. I no longer have the D7100. There is a way to save SOME settings on the D500 and it uses two menu options. I haven't delved into that too much, yet; but, I will.

I have the a6000 and I've been using the AEL button for BBF. Admittedly with mixed results.....

True again, under very limited circumstances "If nothing moves (you, the subject). Under those
conditions BBF also only requires one finger because removing the second finger from the BBF
locks the focus, hence only one finger needed to push the shutter button.

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?
I use bbf all the time and have for the last year.

But he's using BBF. "Normally", I think, you (I) would disable the shutter release button from focusing when using BBF.
If you have selected BBF from the camera's menu the half-press-to-focus function of the shutter button is disabled.

Which camera has a menu selection called BBF? The cameras I have don't have that in their menu.
To set up BBF in my cameras (D7200 , D810 , D850) requires that AF Activation by the shutter be removed. If it is not, it will also continue to focus when pushed halfway.

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.
Does this work for you with back button focus set up? I have found on my D7100 that with back button focus the camera will not focus when using any kind of cable or wireless remote. If I need to focus I have to go to tje camera and use the back button first an then shoot. I usually have to switch back to using the shutter release button mode in order to get the camera to focus while using any remote.

I don't own a cable release ... yet. Would you be able be more definitive than "I think that ... it won't focus". I'd like
to find out, where did you get your information so that I can read it too.

ON my nikons, you must focus first with the Back button and then hit the remote to take the photo.

Once BBF, you will never go back.[/quote]
I am totally ignorant about BBF. What is the advantage?

Yea, that is what I am finding with my D7100.

One very basic advantage would be, if you were on a tripod taking a shot of a waterfall, you could first focus where you wanted your focus to be, then roll your focus/exposure point to the brightest part of the waterfall for exposure, right where the sun is hitting it, and then click the shutter button. This way you have exposed on the water which, if not exposed correctly you might blow out, but focused on the overall scene as you wanted. Another advantage is that, while shooting wildlife in flight, you can easily keep clicking the back button as the wildlife moves along if it is moving out of the focused range or just leave it as is if the bird does not move out of the focus range you've set. Once you set the focus it remains at that setting until you hit the button again. If you use the BBF for awhile it becomes very second-nature to use it correctly.
