XT1 - how to enable focus tracking?
2 months ago

I can't figure out how to enable focus tracking on my XT1. Although I found no mention of tracking in the manual I was under the impression this feature was one of the things that set the XT1 apart from the other X models. On my other cameras (D800, RX100 etc) I can set the focus rectangle on a moving object, enable tracking and have it follow that object even when it goes offcenter .

I typically shoot in single shot mode. When I set the camera to continuous focus no matter what autofocus area I choose I can't get the focus rectangle to lock on and follow an object.

Can someonee clue me in on what I'm missing here or am I  just dreaming that XT1 can do this.

Thanks for any ideas here.

Thanks, good test report. However I don't consider this focus tracking, it appears to just be very good high speed autofocus. Focus tracking means the focus locks onto an object as it moves around the image frame so you can compose with the object offcenter. If focus tracking was really working the focus box would move with the object no matter where you point the camera. And it would stay locked on even if you weren't triggering the shutter at that instant.

I'm surprised I don't see this feature on the XT1 as my P&S RX100 and even my old Oly XZ1 can do this.

Oh, you meant Read the Manual! I usually see RTFM for that Being a software engineer I thought you meant "Release to Manufacturing" which is an operating system version number. I also thought of Remember the Milk before your intent dawned on me. And if you'll note I mentioned in my OP I couldn't find anything on tracking in the manual.

You could have then answered RT(F)OP

The only tracking I see it when Face Recognition is active (haven't try yet).

And of course the one is in the link above.

I think that continuous focus mode is broken on the X-T1. At least, when I try to use it, it hunts constantly, even though the manual says that pressing the shutter release halfway should cause focus to lock on the current focus area. Interestingly, when I take pictures while the focus hunt is in progress, they always seem to come out sharp.

I will be surprised if this mode is not improved in a future firmware update.

I think it's working as intended - continuously checking focus at that point. It might be confusing if it doesn't indicate focus lock though.

Dabbler, I am also looking for the promised focus tracking function in XT-1. I actually thought, that when you freeze the moving subject in focus rectangle, the camera fill follow it at least in the group of 9 central rectangles. But it does not work, immediatelly when the target is out of chosen rectangle, camera looses the focus.

Camera focuses fast on moving subjects, if those stays within chosen rectangle, but this is not effective enough.

Maybe smith come with new firmware.

I think that there's a misuse of terminology here which is leading people astray. From what I've read, the X-T1 will keep focus locked on a moving subject kept in the centre of the frame where the PDAF pixels are. Go outside of that area (9 AF points?) and it will let go.

With other systems mentioned, how do you "paint" (or "unpaint") your moving target?

The recovery is slow. Used it for hurdles this week with the 55-200. Burst over one hurdle was fine but letting up and then trying to burst over next hurdle doesn't work. My 7D and 70-200/2.8 blows it away in that respect. It just can't regain focus fast enough.

It did pretty good with long jump and shot put.

The screen refresh is slow for sports but it still captures the images.

Now maybe it's the 55-200 that can't handle it. I'm eagerly awaiting the 50-140/2.8.

I think terminology is an issue.  There isn't focus tracking in the Nikon (and probably Canon) sense.  Even face recognition probably isn't tracking a face, just continuously looking for faces.

Rather what the X-T1 has is predictive autofocus.  Under certain situations the camera will predict in which direction a subject is moving and how fast and attempt to move focus as the subject moves, not after.

You get this in AF-C with CH modes.  This locks you into the centre 9 focus points.  What is not clear, and isn't clear from the manual, is whether you also get predictive focus in other combinations of modes if you restrict yourself to the centre 9 focus points.

A little more documentation from Fuji on whether this works in other modes would help.

Correct.  I will add that it will hold focus on that moving object (as long as you keep it in the focus box, which does not move around the viewfinder) even if it passes behind closer objects, like light brush and tree branches, that would otherwise grab focus away from the subject.

Frankly, this does it for me.  I never expected it to move the focus box with the moving subject.  Does ANY camera do that?

Mirrorless?  Not that I know of.  dSLR?  Yes.

Brian, thanks for clarification, I have question to that CH and AF C are clear. How do you set other AF parameters ? I am trying with Area and choosing one focus rectangle (1 of 9 middle ones). When I shoot with this rectangle covering the moving target I have a lot of keepers. But if I loose the target with the chosen rectangle and target is within the area of one of 8 middle sensors left, all the shots are unsharp. Predictive focus tracking in my Nikon D3 does follow the target within the group of sensors I choose (one of the possibilities).

Thx.

And that's the point, the X-T1 doesn't do focus tracking, only predictive focus. So it won't automatically switch from one focus square to another in order to keep the same subject. Perhaps make sure that the focus square is as large as possible?

TBH, I don't use this feature much so I'm not sure that this will work, but perhaps you could also try multi mode rather than area mode for selecting the focus point, when in AF-C and CH.

Nope, that doesn't seem to work.  It uses points outside the nine PDAF ones, so it isn't doing predictive focussing in that case.  I guess you use a larger focus square, but maybe not the largest.

Brian, thanks, I tried in-between.

But one is interesting. When you put camera to AF C and CH and set Mode to area in the Menu, the inner 9 PDAF crosses are yellow marked, when you are choosing the focus rectangle. When you choose one of 9 and press OK, the yellow crosses are gone. Are they yellow highlighted only to show, which zone can be chosen for PDAF predictive focus ?
