Disappointed with Fuji X-T1 Firmware 4.0? We have tipps for you...


Recommended Posts

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 used all the right setting - AF-C, HP mode, 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.

 

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

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.

 

Ever heard of viewfinder blackout?

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

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

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!

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.

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.

Hi. I know I'm late to the party to have comments on the firmware, but one thing you should also keep in mind is how the phase detection works only with vertical lines when the camera is in landscape orientation-- so subject tracking will be heavily improved if you are tracking vertical lines. If the subject has more horizontal lines, you will have to have the camera in portrait orientation to take advantage of phase detect af. Xt2 better have cross type pdaf.

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.canon.com/resources/articles/2011/1dx_af_pts_article.shtml (Page 2, 4 & 8 points expansion)

 

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

 

 
 
 
 

 

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.

 

 

That happens to me even when shooting not moving subjects using AF-Single set to one point at minimum square dimension (which I don´t why it´s a square instead of a point) specially with wide focal lengths 18-35mm ... The speed is ok, but the AF is still far from being accurate, and at this point I´m not sure if they can fix it with more firmware updates.

 So looking at the tips, and the venting over the firmware..  

 

Seems like PDAF might be the biggest pain, because it's not compatible with so many other features of the camera..  (can't use ES, FD, etc).

 

Was getting so wrapped up in these "must do" tips before I thought about it and realized I don't spend my days chasing cyclists down the street... :D

very true, I have shot some cyclists and motorcyclists just for kicks and then returned to what I do more often than not which is sigle shot, no auto-track autofocus if not completely manual focus.

 

This whole business of the improved AF, in reality, only ever improved the performance of the 60mm autofocus for me.

 

But of course it was marketed as the panacea for everything for months and so, when it arrived was rather more anticlimactic than most would have liked.

PDAF and ES are perfectly compatible.

    • Cheers! I hope to enjoy it as much as I have enjoyed the Spottie I grew up with and which will remain in my bag for life not simply in my bag, but with a roll of film in it, and more to come. I'm coming at the XT5 from a very weird angle. It sort of goes back to unpreparedness. I found myself with my Spotmatic in "the Garden of Ireland" - Wicklow - beautiful county. I was spending a week exploring its beautiful valleys. When the batteries on my Spotmatic failed, I reached into my rucksack for a replacement set. There were none. So I shrugged and decided I had to use my eyes to meter. Things were cheaper then. When picking up processed films the photos came with a new film thrown in, so it was easier to take that decision. Within a few months I was getting nearly 100% keepers - at least in terms of focus and exposure. So circumstances forced me to be ever vigilant of light. I've had many other cameras since then, but the bare bones (it doesn't even have a self-timer) Spotmatic was an ever-present. Expense has forced my hand, though. That and some curiosity. I feel as if my first car is a Ferrari! In fact, when I explained at the shop that I was an experienced photographer looking for a digital which placed the emphasis on stills, they tried to force a €7k model on me. That would be a step too far. Thus my experience in approaching this camera is somewhat unusual. Thus far I have had great enjoyment with it. I was thrilled on opening to box to discover that I was getting utter rubbish from it. Yes!!! I had to learn how to use it! Praise the Lord! I also found a magic button which was the answer to my dreams - the diopter adjustment. That's how naive I was (and am) about the digital offerings - this was an enormous and hugely welcome surprise. I've been learning. The supplied kit lens is not ideal - a 16-80mm zoom. It's pretty sharp, but demanding in manual mode. My old glass reminds me of my father's Opel Senator, which was forgiving to the point that it would comfortably take off at the lights even if you'd mistakenly selected third. My old glass is much more forgiving. At the moment, I'm leaving everything to automatic ISO. I'll wean myself away from that quickly enough, though. in the past I'd retrofitted my son's lenses to my older kit, and found that you needed to be much more precise. I guess when you're designing something which will be adjusted by algorithms then you can make the continuum as tight as you want. My son laughs at me. "You have bracketing mode if you want, Dad.", he'll remind me. "Use burst mode.", he'll add. Some of my habits are deeply ingrained, though. Two other things people find odd about my photography: I never ever use post-processing - what comes out of the camera is the final product. Secondly, I have never once taken photos where the subject is a human being without first requiring a lot of persuasion. 
    • Seconding this! Would be nice to preview a desqueezed image in camera + output it via HDMI.
    • I found my answer. Actually you can assign the profile from a .dng conversion but not from a .tiff conversion. I hadn’t double checked the .dng option.
    • There's no implied threat. I'm just saying that you're going about things the wrong way. Now you're throwing conspiracy theories and mistresses in and, unaccountably for a photographer's forum, the word "buggery". Complaining and nagging may work for you, but I don't see why innocent posters here should be caught in your crossfire. If you want manual shooting, I'm with you. This is my first digital camera. In all of the various bodies adorning my shelf I haven't put a battery in any in over a decade except where the camera simply won't work without the presence of one. People have actually offered me high-spec DSLRs as they upgraded, but this one was the first one I wanted. I've had to change my MO massively in every way. I accept that, because it comes close to realising everything I need from it. Not 100%, but close.  Y'see, I get the fact that the manufacturers have a huge pool of customers to satisfy and as one of them I know and accept that they're not designing a custom camera for me alone. I accept that and I get on with it.  The solution you were offered is not a fudge or a workaround. It is a logical exploitation of a design feature of the camera: the ability to assign commonly-used functions to a button. That is an excellent customisation option. I'm going to gradually exploit that as I gain experience with the machine and learn what I need most readily at my fingertips.
