Can istDs fire in AF when not in focus?

I've been searching the menus and the manual but can't find the answer.

Can you shoot a shot on the Ds, when in AF mode, when the AF hasn't achieved focus? I thought I'd seen that it could, but can't find the answer.

This is for when you want to get the shot that will soon disappear but it hasn't locked focus yet.

With AF-C you can

That sounded a bit like a commercial from the dark side but AF-C is designed to do it.

Well, some of all those blury pictures has to come from somewhere. They can't be all manually misfocused.

But really, yes.With the AF set to Continues mode you can just shoot away.

But if I haven't got time to wait for the AF then I haven't got time to go to the menu to change to AF-C! Any other way?

I don't think you don't need any other way. Try it; just switch to AF-C and leave it there and see what you think. It hasn't stopped me from taking single pictures and not pressing the trigger until focus was locked.

you need to check the special functions menu.

The *istD has a function to allow this, but the K10D does not. I suspect each camera type is different.

I have raised this issue wioth pentax, as it should be the usere who decides when to shoot, not the camera, especially when they market the K10D as a pro camera

I agree. I thought it was in the menu somewhere too. Af-C is a pain when recomposing the shot after focussing.

sorry for digging up this old thread.

but may I ask, what is the best work around you have found?

I only have my *istDS a few days and try hard to really like it, but not being able to fire when not in focus in AF is going very much against my style of photography and already has been disturbing me quite a few times.
and: as I still could exchange my camera for a K100D: does the K100D have the same issue?

thank you,
Andreas

I am going to get out my soap box now --- be forwarned.

De-couple AF from the shutter button - use the OK button. You want to take an picture - move your thumb off the OK button and press the shutter. Boom ---- the camera takes a picture when the shutter button is pushed.

this is the menu option: OK button when shooting > 4: cancel auto focus?

so:
first I disable autofocus by pressing OK,
and then I enable it again by moving off the OK button just 'before' pressing the shutter?
won't the camera then hunt to get the focus right again?

thank's a ton!

From an old post:
On the *ist Ds it is the custom menu:
OK btn when shooting: option 3

On the K10D it is the custom menus:
AF Button Function : 1 Enable AF
AF by Press Halfway : Off

Do not put disable AF.
Work flow is:
point the camera at the "thing" you want to focus on:
push the OK button - which will set off the AF mechanism.
Once the "thing" is in focus - release the OK button.
Compose - get your exposure --- whatever - push the shutter button and the camera ----- takes the picture - no hunting, no searching.
Push the shutter button again --- it takes another picture - no hunting etc.

I use this because I want to control when the AF function is working - not have the camera try to determine what is in focus. The documentation for the Ds is terrible on this feature.

I use this method, because it follows the way manual focusing worked in the old days. Twist the barrel until the "thing" is in focus, set the exposure, take the picture. With AF and de-coupled shutter button - just change twist with OK button.

It works for me - your mileage will vary - whatever you do is OK with me, I just do what is normal for me. I do not like giving control over to some arbitrary internal computer that thinks it knows what I want.
