I never used BBF on my 35mm film cameras which had it, because I was used to the shutter button. Then I got a DSLR and decided to try BFF, and have never gone back. I'm often slow to change, but once I do, I stay with the new. I used cable releases on MF film cameras, but never felt the need with a DSLR. on my DSLR I tend to use the timer to release the shutter.

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 have been using it for more than 20 years, and I can not think of anything that would make using it unfeasible!

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.


Thanks for the reply.

The only situation that I have discovered is when a relation wanted to take a snapshot of us with my camera. Trying to explain BBF was not an otption, setting the camera to auto mode fixed that, without changing any of my settings. So, short answer is no, except of course if you use manual focus lenses, and then it doesn't matter either.

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 are you able to use both? So you use BBF and then press the shutter, it will possibly change the focal point?

In the menus I can set the camera up for 4 completely different and unique situations and label each thusly. One I could BBF and use the shutter release only for that. I can program the BBF button for group, or dynamic, or single point. I could also use one of the other buttons for
a different focus option.
I probably have not explained this very well. I apologize.

I use BBF on my D7200 and as you say, I will "never go back", but even after reading the posts above, I remain a little confused about
exposure. Is the shutter button still handling exposure?

1. if so, and I don't at least hesitate at the half-way point with the shutter button, then camera doesn't have the chance to set proper exposure. (I have had a couple of unexplained "all blue" shots and wondered if that was the issue)

2. If not, and the AE/AF "back button" is handling exposure along with focus, then I assume that if the light changes, but you don't re-push the back button, then you will have a picture in focus but with wrong exposure?

somebody enlighten me please.

That's right; if the light changes you have to re-push the back button. But why would you be waiting so long after focusing to press the shutter that the light would be changing?

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.

Not an answer, but another question: Does TTL Flash function properly when using BBF? (I'm on Olympus system)...

Agree. Need to use BBF all the time. Hard to turn your mind on and off

YES.. If I am shooting with a remote.. Like the Vello Freewave, Vello Shutter Boss II or a similar device, it will NOT focus before shooting (it doesn't press the Back Button to focus). I have a Nikon D7100, a Nikon D7000 and a Nikon D610.... and these have a completely programmable (U1 and U2) setting on the control dial... along with auto w/flash auto wo/flash Aperture, etc. So, I created a U1 setting that autofocuses (like original setup) for use when I am using my remote and not manually or back button focusing.
