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?
Just been out on the front to try it on cars coming towards me and recomposing flower pictures after focus lock,i think ime going to like it.
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
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.
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). ???
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.
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!Shouldn't continues focus with focus lock guarantee sharp shots all the time? No need for AF-S except in special situations?
