Fujifilm Autofocus DOES NOT WORK properly Locked

Surely it would make no sense for the camera to stop down prior to AF? (Unless the light is so bright that it blows everything out when wide open.) That’d just be crippling itself.

In AF-C it stops down first

I guess it needs to be able to fire the shutter at any moment. Never used AF-C in my life, I confess 🙂

Yes I had my first day here, where I contributed to some threads, then created my own thread entitled ‘your 3 favourite photos’, I didn’t roll in with ‘Fujifilm Autofocus DOES NOT WORK properly’ followed by some very suggestive comments in the post below.

I hope you can understand the difference between the two approaches.

By the way, my sharp shots are easily viewable, that’s because I’ve linked my photography in my profile page, as I’m a great believer in people being open and honest about themselves.

Look, I just signed up here in order to see if more people know about this issue, as it drives me nuts and ruins the total image of a company for me, whose products I happen to really like otherwise. I have no interest in promoting myself, as I am not a paid photographer, neither I am interested in presenting myself in a certain manner in a forum... I am more the real-life kind of guy Dont judge people so quickly 

Lets stick to the topic now

Either your technique is profoundly flawed, or your camera is just plain wonky.

Have you tried this with the EVF instead of the OVF?

I almost always use AF-S with a full-press of the shutter button (by far the most reliable AF method, IMO) or manual focus. With a static subject my AF hit rate is easily 99% even with the quirky old slowpoke lenses. I've found the focus scale to be of no help at all and a complete waste of time and EVF space.

I went over to this crummy little garden shop next door to where I work the other day with my good old X-T20 and 56 f/1.2 (probably the most troublesome Fuji lens of all) and decided to limit myself to f/1.2 (which I almost never shoot at) and only AF-S with a full-press of the shutter button (no half-press first) to see just what kind of hit rate I could manage. Except for a couple of shots where the 30 mph wind blew my target away from the focus box or I was closer than minimum focus distance, every single shot was in-focus despite the razor thin DOF at close range. I don't know what you doing, or if the X-Pro3 just has the worst AF imaginable, but I really have no problem at all focusing any of my three Fuji cameras (X-T2, X-T20, X100V) ...and that includes in low light.

These aren't great art and most would look better stopped down a bit and/or manually focused a bit differently, but every one is in focus precisely where the the AF box was positioned and I don't think you can ask more of an AF-S focus system than that.

Hi,

I just looked at the two images with the yellow campervan. (It's late here in Oz). They're obviously different. The degree of focus on the van is similar (if you check out the ventilators on the side of the van). However, the background tree above the van is rendered very differently between the two images.... despite the same reported aperture.

The background tree in the first image is much more OOF. The tree in the second image is less OOF and closer to being in focus. The EXIF is saying they were both shot at f4. I don't know what happened and I don't know where the focus point was placed. The camera was moved slightly - the image centre differs a little between the two images - I don't know if that has a bearing on anything. It may not. However, the very different degree of focus in the backgrounds would suggest that the focusing distance was different. The result being that the van sits at a slightly different place within the DOF available at f4 in both photos, but the tree in the first image appears to be further outside the DOF than it is in the second image. Hence it's rendered softer. Making sense?

I don't own or use the X Pro cameras, I'm an XT person. Nevertheless I still don't use the distance scales in the EVF. I didn't find the scale accurate in my old XT1 when using the 18-55. It was better with primes.  The camera focused correctly - the AF and images were fine, but the distance reported in the EVF was not accurate. I haven't checked them on my XT4 - I just don't use them. I either rely on the AF, which I find absolutely fine, or focus manually by eye using the MF assists. My personal choice is magnification rather than split image or focus peaking, but that's subjective. Nor do I rely on the camera's indication of the DOF via the blue bar. In my experience DOF apps like DOF Master are better than the indicator in the camera.

I don't know if any of that helps. I hope you resolve what your camera is doing.....

Regards, Rod

Maybe so but you are asking for scepticism:

- a new user ID

- a user ID specifically chosen to show loyalty to a different brand

- a post title that is designed to irritate those that use Fujifilm cameras

- a post title that actually SHOUTS the message

- rather than coming across as someone trying to understand an issue you are having - being absolutely sure it is the camera model (or brand) that is the problem

- refusing to post original images as evidence

I posted pictures 4 of them

Check the left front tire.. its the most obvious spot to see a difference.

I took the 2 shots without taking the eye of the viewfinder, if I moved ever so slightly it cannot move the focus distance by that much..

Yes, my technique is overly flawed, basically my whole life I am shooting blurry photos Be it with Nikon or Fuji ... *irony off*

I wrote that it appears with both EVF and OVF.

You've had plenty of on-topic responses but you have to give us something to work with. It's obviously not a common problem with Fujifilm cameras.

How about putting the camera on a tripod and taking a series of photos with the same settings and then sharing the results - it shouldn't take long to get a few good examples.

Just curious: who says that? My understanding is that to focus directly with the chosen aperture, the camera has to be set to manual focus.

And one tip: fujilove.com has a long series on focusing by Rico Pfirstinger.

Nobody needs to say it, just observe your lens when focusing in each mode. 
Thx for the tip, but I am not an amateur beginner who needs explanation on how to focus an AF camera. 
Judging by the kind of feedback the majority of people provide, I am better off looking for support somewhere else.

Appreciate all the rest of the cool and kind guys for having contributed

thanking for what? Judging me based on my new account? On my backed up accusations some fanboys do not want to read? For telling me I am too stupid to press a button?

The ones that have been kind and cool, have received my appreciation.

No such problems with my XT4 and  XPRO3 .AFS is a tricky AF, the smallest change in position , whether from the shooter or the object, gets an out of focus!This is the main reason I always use AFC , even for portraits.Only for architecture and landscape , I tend to use AFS sometimes.

It seems to me that you have chosen to ignore some useful advice provided here.

Which one?

Nobody can explain why the camera measures the distance to a static object differently every time...
That would be already a step into the right direction...

This thread has degraded into a series of personal attacks, with more than one individual stirring the pot.  As such, I will lock the thread and give folks another opportunity to raise the issue and discuss it without getting personal along the way.  Further such issues will result in temporary (or worse) loss of forum privileges.  Enough is enough.
