Guys, a little help here please. I want to try this with my D5300 but am unsure what item to select in the options menu. Do I go with "AF Lock Only" or "AF On"?

On edit: What are the pro's and cons of 9 point focus? Is it likely to degrade sharpness?

Set the "f" custom control to AF-On and then Auto Focus to AF-C It works great. I have been using it on my 5300 for a while now and love it.

I think the 9 point focus vs other settings depends on what you are shooting. Birds in flight, I usually set it to Single Point. For some other situations I use 9 point or matrix. Single Point you are either on or off. 9 point can have difficulty focusing if the scene is cluttered with other things ie a bird in a semi-thick bush with lots of branches. (Others with much more knowledge than I will answer this part better, I'm sure. Ha!)

I guess we must have had a similar upbringing Mike. When I was a kid in Norfolk my Mum used to tell me to go play with the traffic in the street but I had to do it without a camera!

You should look at the back-button focus videos... Back-button is AF-S when you press the button, but switches to AF-C when you hold the back-button in... and then goes AF-S when you release it...

Best of both worlds without all the menu fumblin'...

edit to fix typo

Guess I know what I'm doing this weekend. :) Thanks y'all!

So unless it went right over my head the consensuses is Af-C using the back focus button, so in the simplest terms
constant focus is where most of you shoot? I like the back button but I have it set for exposure lock so when I'm
shooting and get a subject overexposed/underexposed I can expose one area, compose the shot in another and get the exposure I'm looking for.
Works great for landscape.

Seems like with this method you've moved the 1/2 shutter focus to the back and I can see that is a specialized shoot but for general shooting
now I'm pressing the back button and the shutter button when one will do both.

No... The camera is set to AF-C... but is NOT actively or continuously focusing. The focusing is only activated when the back button is pressed... If you press and release the button, it AF-Ss... If you pressANDHold then it AF-C until you release the button...

I get that I just don't see why, now I'm pressing the back button and then pressing the shutter button and I'm loosing my exposure lock
and that seems way more beneficial.

I guess it's all in preference and I prefer exposure lock.

My origional question was lost along the way.

You need to change the Shutter button to Shutter ONLY...

Press the back button to focus the camera, and press the shutter to fire the shutter Only and and you don't loose the focus.

I see what you are saying (I think). You are wanting to be able to lock in your exposure setting which you feel you are losing by setting the AE-L/AF-L button to BBF. In one way you are, but then again you really aren't if shooting in "M" mode. If I understand you, it is possible to set your exposure setting all manually (f-stop, Shutter Speed and ISO fixed not auto). Set it for the condition you want. Then once it is set you can use BBF.

I realize you are wanting to lock the exposure with the AE-L and then let the shutter button focus when taking the photo. That works and may really be the best case scenario for the way you shoot.

We have to determine what works best for the situations we are shooting in. I don't know if BBF will benefit your shooting scenarios and I see your dilemma and can't tell you what benefit one method will have over another.

menu option C1 "Shutter-release button AE-L" set to ON should set the shutter to Exposure lock...

Now... you can use back-button focus to focus the camera, and pressing the Shutter button, instead of re-focusing should Lock the exposure...

The back-button focus's biggest benefit is that it puts the option of AF-S or AF-C within the reach of the same button, without looking away from the view-finder to reset the focus modes via the LCD screen or Menu...

So Fred, help me get the sequence of using this setup for getting the picture as the OP seems to want. With Shutter-release AE-L ON you will need to actuate the shutter 1/2 way to set the exposure to a preferred area and then move your camera to the point you want to focus on using BBF and then finish actuating the shutter (Press shutter button the rest of the way). ???

Looks like back button to set focus and shutter button to take the photo.

I never wanted this read my original question.

Or I suppose you could reverse the order and BBF on the subject you want, relase it and then point to the exposure area you want, 1/2 press shutter, move camera back to focus point and finish activating shutter button.

I shoot in manual mode with auto-iso... so I manually set my aperture & speed first... I then focus, and shoot... Same work flow if I've turned off auto-iso... I never shoot auto, A,P,S... well, almost never...

Shouldn't continues focus with focus lock guarantee sharp shots all the time? No need for AF-S except in special situations?
Yes. My only problem with BBF AF-C is that I don't always catch that fast flying bird at the focus point when I bang the shutter. Ha!
