I shot some ice skater yesterday and although I got some in focus shot I also have a lot of oof ones that goes straight to the bin.

 

Problem is 3x3 zone is simply too 'loose'.

 

Sure you can argue that I should use single point, but what I think is Fuji needs to implement something like Canon DSLR with 4/8 AF points expansion explained here - http://www.learn.usa...s_article.shtml (Page 2, 4 & 8 points expansion)

 

Anyway samples below shows what I mean, images from a burst sequence -

DSCF4615
DSCF4616
DSCF4617

 

Oh well maybe I'm expecting too much, but I feel there's still plenty of room for improvements if Fuji gives us more flexible AF modes to improve it further.

my short experience with AF tracking, using all the proper settings for it, is very good indeed, I suggest you retry by using those settings

I used all the right setting - AF-C, HP mode, MS only, Ch, 3x3 zone. The problem was at that distance as shown in my samples the 3x3 zone is simply too large and imprecise, it switched focus from the skater onto the background and back.

Obviously single point would have been better but I couldn't keep switching the modes when actions were flying thru left and right.

I used to be a 5D3 shooter and imo 4/8 points expansion would have been perfect in such situation. It's def something that Fuji can implement and improve further.

Overall the update is better than nothing, but it's all of a catch up game and still clearly behind against its main competitors such as A6000, GH4, EM1 etc. by a fair margin.

I'd never use CH.

Seriously? That's your solution?

Cl would not capture as many frames in such fast paced action. Besides burst speed has nothing to do with it.

With fast action like this shooting Ch is a given.

Hi guys,
 
I have a problem with the new firmware. With the 50-140 on, the IS never stops running. I have set it for "Shooting only", but it still runs all the time, as long as the camera is on.
Tips?

I'm pretty certain that this is normal behaviour for this lens.

I have tried only a few shots with the 50-230 at 230mm  they were all well focussed. Different strokes for different people! Good luck!

…And why did you need a tracking AF for this sequence, exactly?

Wow I'm amazed at this board with so many fanboys and their condescending replies.

I posted a legitimate concern with sample photos and these are the replies I get? Great....

Where do I begin.....as I've said in the previous post the actions were flying left and right, there was actually 4 female skaters in the ring and there was no way that I could keep switching af-s to af-c/single to zone.

You are absolutely right about not needing tracking af in the particular sequence I posted, but the problem lies with zone mode algorithms.

First answer this question - Is the camera supposed to lock on the CLOSEST SUBJECT within the zone (either 3x3 or 5x3 in Ch) when using zone AF mode and continues to track if camera is put on af-c?

If the answer is yes, fact that it locks onto the subject in the first few frames (note the four samples I posted wasn't every single shot in the sequence), lost the subject in the next couple (focused on background) and back onto the skater again means the zone af isn't that great after all.

The skater was spinning at the same spot which means the camera to subject distance remained constant, which means in zone AF mode it SHOULD lock and continues to focus on the subject without jumping off.

This alone shows the Fuji's zone implementation is flawed.

Irrelevant to my problem, but thanks for pointing out another X-T1 shortcoming.

Yes, it always makes that noise.

Hi,
Thanks to all involved for tips and trials on FW4
So far so good for me

However I have a question concerning the interlocking of spot metering and the zone tracking.

On which point in the zone does the spot meter take its reading: the one in the middle of the zone? The one used to focus on pressing the shutter? Or...?

I have looked at many of the posts (but not all) and have not seen this addressed (and it does not appear to be addressed in the xt1 additive to the manual either).

Thanks and have a nice evening
Jeremy

Besides burst speed has nothing to do with it.

 

For me, it has a lot to do with achieving good AF tracking performance. Hence my recommendation.

thanks for the reminder re MS+ES mode disabling PDAF!  But I don't really understand why this needs to be a user intervention - couldn't the camera use PDAF when the camera is using the mechanical shutter and keep doing so until the aperture and light combo pushes the shutter into ES mode and THEN have it auto disable PDAF at that point?  Now I have to keep switching ES on when shooting wider aperture with the F1.2 in sun.  I guess though that the rule is if shooting any moving subject then keep the shutter to MS mode only which I agree does make sense.  Nice photo by the way!

Pretty sure it does in tracking mode (meaning AF-C and either Cl or Ch).

Not really. AF is limited to the first frame, though.

Yesterday I had some time to test firmware 4 on some dancers. Its an improvement over firmware 3 but its nowhere near the AF speed of an DSLR. And maybe I would have had more keepers with AF-S then AF-C. Maybe its also because the light in the room was not that great. Hopefully in the next 3 to 4 years the mirrorless cameras catchup with the DSLR performance so I can leave those big cameras / lenses at home.

I suppose the best is to accept the camera as is. If one wants something else there are easy options.

 

Things then to be as they are and rarely they are as we think they should be.

Chaps

 

One thing I noticed with Fireware 4 is in the AF sub menus the Release/Focus priority settings are both default set to release priority (ie for Single Point and for Continuous)

 

This means the camera is prioritising release over focus accuracy.

 

Might be worth checking this setting if you have not already as that might help with accuracy of focus.

 

+1 as well to using CL mode. I used to always use that on my X-E2 as on the X-E2 in CH mode it would not re-focus between frames, so even in C mode on the front dial when in CH it would focus for the firts shot and then lock at that focus for remaining shots.

 

I found that Cl was actually quite good for most applications good example my daughter going down a slide and running towards me, in CH mode I would get about 17 shots of which the first 4 or 5 were vaguely acceptable but nothing special. Same thing in CL mode I would only get 6 shots, but 5 of them were very sharpa nd one passable none were as badly focused as the CH mode. I would rather have less shots and them all be useable than lots of not very good shots. YMMV

 

Now the X-T1 does re-focus between shots, I think the shot rate does go down slightly if you have focus priority on, but its not as slow as CL, so I think that CH plus focus priority is probably the sweet spot, but I need to experiment more.

 

Most of the above was done with Single AF, not played with Zone AF and burst shooting yet. I have mainly be focusing on comparing it to X-E2 with a view to which camera I keep.
