What's the deal with the X-T5 autofocus?

Go to last post
I'm a Sony guy and also have a Fuji X100V. I love the Fuji colors but not the autofocus and was excited when the XT-5 came out and new focus system. Looks like I will wait till they get it figured out. I'll keep using my Fuji for landscape and Sony for fast moving items.

My Sony's are so simple just back button focus and eyes are locked in.
 
Have You guys read comments in those YT videos? Many user reports same behavior from their X-T5 (false AF confirmation). Its to many, to just belive that is user error. Global user error, to be exact because people report exact same problem.

For me it's lookin for poor AF algorithms in newest Fuji cameras, or lack of processing power to compute all this AF data from sensor. Nikon needed to release Z6 and Z7 mark II with adding another EXPEED processors, to achieve enough computing power to make AF in continuous tracking mode finally reliable.

When reading reviews about X-H2s vs X-H2, it's very clear that more precise AF in X-H2s in continuous tracking mode, works better and more reliable because more computing power in X-H2s compared to X-H2.

I do rather wonna stay optimistic, but I'm not sure if future firmware upgrade will fix mentioned failures of false focus confirmation in AF-C mode, to the level of let's sey.. Nikon Z6II or Z7II. Time will tell, but current Fujifilm marketing policy is disturbing (this big hype around new and reliable AF)

The XH2 and XH2S use the same processor. They have the same amount of computing power. Any advantage the “S” has in terms of tracking accuracy are due to the stacked sensor and having fewer pixels to process — not computing power.

I do think this post gets an an important misconception however, that being that the real-world standard for AF performance is 100% perfect accuracy in all situations. No AF system does that in situations other than with a well-lit, static subject. Subjects move — forward, backward, up, down, diagonally — and then pass in front of and behind and near other potential subjects. We often make a photograph quickly without as much time as we might want to carefully frame and locate AF points.

So to say that a camera doesn't get 100% accurately AF doesn't really tell us that much. More useful is knowing when and how it fails and whether the failures are above the rate typical of other cameras in similar situations.

Yes, You are right ;)

Guess it can also depend how you define computing power.

Raw processor speed they are the same. However, if defined as frames per second calculated it isn't.

Wonder if Fuji tried to minimize costs by using a processor that is just barely enough and didn't leave much headroom. Might be the reason for choppy refresh rate of AF box tracking in the viewfinder. Distribute computing power for other functions. Gives a less sticky experience than Sony/Canon.

For sure I don`t know how you use your camera, but based on this statement (and I do not want to be offensive) you are not a demanding user. I own an A1 and I own an X-T5 and from AF system point of view, these are on the 2 ends of the market for any camera released in the last 2 years above USD1000.

Who do you think you help when you imply, that the X-T5 AF system is as good as the A1 AF system? Fuji had AF issues. Fuji worked on the AF, it got better, but still behind the market. Fuji still have a lot do. /And we keep buying Fuji products to support them in their efforts./

I don’t know about the other cameras, but the X-H2S isn’t far behind the A1, and in some circumstances better - such as when hair is in front of the eyes using eye AF.

Wish people would make actual side-by-side video comparing the X-H2s vs A1/R5 etc with different environment/subject instead of making anecdotal subjective claims.

Tried out a X-H2s myself after hearing those glowing comments but was left with mix feelings. AF while much better was definitely not close to what sony/canon can offer.

Oh come on. How can one comparing at $6500 and $5500 camera to a less than $2000 camera? The A1 and Z9 are both stacked sensor cameras with a high read out rate which helps autofocus because the AF control loop is updated at a faster rate. The A1 and Z9 represent two different market segments.

I also expect the AF performance of the XT and XH are as much determined by the lens as the camera. Not all of Fuji lenses are quick enough to support a rapid AF systems. And at least one of the YouTubers was running his mouth off about testing he did in "Release" rather than "Focus" priority. That pretty much tanked his creditability. If one tells the camera to take the shot - in focus or not - one should expect to see out of focus images.

Yep, some sort of psychosis I expect. Comparing the XT5 to the A1 and Z9 is like comparing at nice Ford F150 truck to a BMW 7 Series or Benz S-class and doing it with a straight face.

We all know that the F150 will be the only one to have a chance to complete the Baha endurance race!

The people who drive a BMW 7 Series or Benz S-class would higher the person with the F150 to do that type of chore. Who knows, the person with the F150 might be the one making a million a year.

Even if all the tests are not perfect, even if all the youtubers are not all pros (Chris Nicolls from DP review included who recently reported this problem), even if certain tests can be qualified as flawed, I think there is enough evidence from others users as well to ascertain that Fuji's updated autofocus is still quite far from being on par with Canon and Sony.

To me at this stage in the game, it is a disappointment.

As long time Fuji user, XT2/XH1/Xpro3 user, I was hoping for better AF performance at this point.

Whether it is because the X5 processor cannot handle 40MP files, or because Fuji just cannot once for all fix its oof/false positive focus problem that has plagued its cameras for generations, it will be difficult for me to find an upgrade path within the Fuji system going forward...
 
It's too bad that legitimate questions such as the OPs are always met this way here. We aren't mercenaries in the camera wars, or at least we shouldn't be.

Just as likely as the argument that these videos are made by people who've no background with the camera - as has been suggested here - is that they're made by people who try many brands of cameras and speak to them relative to what else is out there. It's perfectly fine for the OP to try to get more information, and this should be the place to find it.

It's quite ridiculous and sad really how many forumers cope and gang up on any opinion or question that they perceive as "negative" towards the brand.

I love Fujifilm but autofocus has been their biggest weak point ever since the X series started and I've stopped believing their hype every time they announce the autofocus has been improved, the fastest, 0.000000001 second blah blah blah. I've been with Fujifilm from X-Trans I and while they have certainly improved their AF, it has not been able to keep up with the competition. And the improvements have been more on the responsiveness of the interface and detection. But as far as actual accuracy and hit rate, the improvements have not been revolutionary for the system. Heck, even an old Sony A7 III can nail focus and stick to a subject better. Not saying the Fujifilm AF is useless or you can't make wonderful photos with it. I'm just saying that it's not as fast and reliable as the competition.

That's why I use manual lenses with my Fujifilm cameras and treat them like digital film cameras. And with manual lenses, startup time and switching from menu/playback to shooting display is a lot quicker too. No AF lenses pulsating and lagging the camera for a moment.
