Focus and cable release

Here's the thing......

On a tripod using cable release, I have tended to autofocus (half press button on my chosen point) then find that the camera will do it again when I go the cable release (which is sometimes ok, but it can struggle in low light situations eg night photography and is also a pain if I want to take several shots one after the other), so have been autofcussing then switching to manual on the lens to ""freeze the focus". This is also a pain, especially fiddling in the dark. I thought maybe the AF-L button would do the trick, but I think you have to hold that button which is defeating my desire to be hands-off for max sharpness.

I'm sure there must be a better way to do this. Ideas anybody?

PS Nikon D750

On a tripod with a remote release then manual focus would be my choice, however if you must use AF then you need to separate the focus from the shutter button, google 'back button focus'. (I am sure the D750 will have this facility)

Hi flowerpot59,
From my experience if you pre focus either with shutter button or cable release and let go the camera will think it is the first focus.
My way around this is to focus the switch off the auto focus on the lens, re compose etc.
I use Canon but assume same may apply on Nikon.

In such situations in the past I have always used manual focus. I do not use a remote release as such but either use the self timer or control my camera from my iPad. About 12 months ago, I set up back button focus so once I have pressed the back button, the focus will not change. However, I would still normally opt for manual focus in these circumstances.

Thanks to those who suggest using autofocus then switching to manual, but that is what I am seeking to avoid. It's fiddly in dark conditions and recently was a complete pain when photographing a model who moved between every shot. I am now thinking about "back button focus" which I believe might achieve the same thing i.e. fix the focus so that the cable release won't try to do it again every time.

That is correct, it removes the AF function from the shutter button, does take a bit of getting used to but IMHO worth it.
