Fujifilm X-H2S Autofocus Tracking vs X-T4, for Wildlife and Performance on Older XF Lenses (XF56mmF1.2 Included)

Share

The French channel Les Guides Fujifilm has published a video about the Fujifilm X-H2S autofocus performance under many different scenarios.

It’s a 40 minutes video where he tests:

  • X-H2S vs X-T4 eye/face tracking
  • X-H2S tracking a running dog
  • X-H2S tracking kids (running and on bicycle)
  • X-H2S for Wildlife
  • X-H2S at 40fps and 30fps tracking (dog and kids)
  • how good several Fujinon lenses work on X-H2S
  • low light stills tracking in a circus
  • low light video tracking in a circus

Lots of stuff, right?

You don’t have time right now to watch it all?

Well, for your convenience I’ve made a summary down below and I’ll also give you time stamps so that you can jump to the section that interests you most.

NOTE 1: when he scrolls very quickly through the images you see them unsharp. This happens because his computer is not rendering at full res. When he stops on an image it gets rendered and it becomes sharp.

NOTE 2: I speak four languages, but sadly French is not one of them (although I understand it a bit). In case any French FR-reader notices an error or wants to add something, feel free to let me know in the comments.

Fujifilm Recommended CFexpress Type B Cards: Why These Four Cards are BEST and Which Ones You Should NOT Use

Share

With the release of the Fujifilm X-H2S and hence Fujifilm’s first digital camera to take CFexpress cards, Fujifilm has updated its list of officially recommended cards to store your files.

Now, all the cards listed below are recommended.

But attention, not all CFexpress Cards are made equal.

  • Some CFexpress Type B Cards can’t record 6K/4K
  • Some can record 6K/4K but not in ProRes
  • Some can record all video formats, but when used for bursts don’t last as long as others
  • Only 4 Card Models can do it all and can do it best

Also, CFexpress Cards not listed here are not properly tested by Fujifilm. This means they could perform very well, too. But they could also have a negative impact on the performance of the camera (or even don’t work with certain features).

This is important to know, as I have already seen reviewers using the Pergear CFExpress Type B card in their X-H2S first looks. Whatever those reviewers say in terms of performance, please take it with a grain of salt, as they use cards that are not on Fuji’s list.

If you treat yourself with a Fujifilm X-H2s, please stick to the recommended CFexpress Type B cards (and also UHS-II cards) listed below.

CFexpress Cards – Official Fujifilm Recommended

Out of all the cards mentioned above, the four cards without any compromise in performance are:

In order for you to get the complete overview, I have added the full detailed chart at the bottom of this article (also for UHS-II cards).

UPDATE: IMX671 is NOT the Sensor of Fujifilm X-H2S

Share

Back on May 31, an anonymous source send me the sensor sheet for the a new IMX671 sensor by Sony.

I was skeptical, and considering our approach to be as accurate as possible, I decided not to share it. I also received the one for the Fujifilm X-H2, and also that one, I did not share it.

Sharing probably fake stuff just for clicks is not what we do here on FujiRumors.

But I guess once the anonymous source noticed FujiRumors would not be tricked to publish it, it started sending that file to several websites, who, hungry for clicks, all published it giving it for granted that this is the Fujifilm X-H2S sensor sheet.

At that point, I had to publish it too, but more because I wanted to warn you that I am very skeptical about it.

So I did what FujiRumors does best: I verified!

Well, I can now say with 110% certainty that the IMX671 is NOT the sensor for the Fujifilm X-H2S and also the other sensor sheet I’ve received, which the anonymous contact said it’s for X-H2, is 110% not for X-H2.

In fact, I don’t know if they even exist, or they are just made up. Or they are just sensor for other cameras (maybe Sony, certainly not Fuji).

But what I can tell you for sure, it’s that none of them is for Fujifilm X-H2S or Fujifilm X-H2.

In a future not all too distant I will let you know the IMX definition for both sensors in a way you’ll see with your own eyes that this was just a fake.

OUR COMMITMENT TO OUR READERS:

In these years I have seen all possible fakes. Websites who claim the X-H line had been axed (but now we got even two of them!!), websites spreading rumors about nonsense lenses like the Fujinon GF56mmF5.6 and much more.

The reason why this happens is simple: they want your attention, your time and your money. And every way to achieve that is legit in their eyes. Yes, they know they fool you, but they don’t care, as long as it brings them profit. The only rumors they get right, are the ones they copy from FujiRumors (without quote of course).

But here on FujiRumors we don’t share fake rumors as we don’t take this kind of shortcut to get your attention and increase traffic.

Our commitment to you: we want to respect your time! And if you honor us with your time, then we want to deserve it by working hard and good, day after day, article after article.

I know that this is the hard way to success, as spreading sensational fake rumors would be a guarantee for traffic (and you can always talk yourself out of it by saying “hey, it’s a rumor, doesn’t have to be accurate”). But that’s not who we are. I just have too much respect for you and your time.

Decrypting Fujifilm Manager Statement: “No other Camera Platform more Suitable to Have both 5th Gen Sensors than X-H Series”

Share

I’ve re-watched the Fujifilm X Summit, and right at the end I noticed a sentence that I think we have to investigate further what it could mean.

When talking about the two new 5th generation X-Trans sensors, the 26MP stacked sensor and the 40MP non-stacked sensor, that will both be featured into the X-H line, the manager says:

and there is no other camera platform more suitable to have them both than the ‘X-H” Series

I did try to wrap my head around this sentence to try to get what he really meant. I see the following options:

  1. It means that only the X-H line will offer both 5th generation sensor options as other platforms are not so suitable “to have them both“. As a consequence to this, all other camera lines will get either one or the other sensor (but not both)
  2. It means that since the X-H line is the most suitable of all, it will be the first line to get both 5th generation sensors, and other camera lines that might eventually also feature both options will come only after the Fujifilm X-H2S and Fujifilm X-H2

What do you think is the most appropriate interpretation of this sentence? Feel free to vote the survey down below.

The Fujifilm Manager is saying that...

BIRD TRACKING with Fujifilm X-H2S with XF150-600 (in Complex Condition) and EYE AUTOFOCUS on Par with SONY & Co

Share

Bird Tracking

Just yesterday I reported about a video by tb- photography, who in 1 minute was able to give us more clues about the real autofocus performance of the Fujifilm X-H2S then some of the big youtube channels in 20 minutes of talks (and in some cases without showing and samples).

And since smaller youtube channels seem to often stay on the piece better than the big ones, today I’ll share a video of an even smaller youtube channel, in fact so small, that this time even I missed this video, but a fellow FR-reader made it notice to me today.

Passionate bird photographer liewwk Nature runs a 860 subscriber channel with hundred of bird photography videos.

He posted a 5 minute video of birds tracking with the new Fujifilm X-H2S and XF150-600mmF5.6-8.

A lot of it has been taken in tropical forest environment, often in tricky and low to very low light conditions and with a complex and distracting background.

In these objectively difficult conditions, Iiewwk Nature writes:

The new system just weight 2.4KG which allow us to shoot 150-600mm (225-900mm 35mm equivalent) which is one best available

This system allow me have >50% success rate 1/125 at 900mm which is my recommended minimum shutter speed for handheld.

The AF is fast and accurate (on bird eye), it may not best in market but it is very good and accurate even at low-light & complex environment.

For the Auto-focus, I think this is a huge upgrade compare previous X series. The Animal Detection just simple amazing

Keep in mind that this is the success rate mentioned is for shooting at 900mm.

In my eyes it already looks pretty amazing. And considering that this is an early pre-production firmware (on both, camera and lens), I guess it can get only better from this point on until the final firmware is released.

You can find the video down below and his blog post about his experience at liewwkphoto.

Eye Autofocus

The second video below is of Lee Zavitz, who used the Fujifilm X-H2 with the XF18-120mmF4 for a portrait session and he is says that eye AF is crazy and it detects the eye even when the eyes are mostly blocked by her hair.

He says he is really impressed by eye detection and he did not expect it to be that good.

It’s still a beta firmware, but it is on par with competitors in terms of eye autofocus.
