VIDEO TEST: Fujifilm X-T4 and GFX100 New Firmware Fixes Auto Exposure Stepping Bug

Share

Just very recently, Fujifilm has released a bug fix firmware for the Fujifilm X-T4 ver. 1.03 and Fujifilm GFX ver. 2.01.

All Fujifilm mentioned was a vague:

Fix of a minor bug during a movie shooting.

Well, FujiRumors could not be happy with such a vague definition ;).

So I decided to try to find out what’s behind it, and despite being on my very last days of holiday in South Italy with my wife, I made quick testings and immediacy reported about my findings in this dedicated article.

My findings in short: exposure change is now smoother (not stepping like before), except in high speed modes (like 120 or 240 fps).

Now, I have no time to make a video and edit it, as I am mainly writing from a beach with a beer/seafood pasta/ice cream/etc. in my hand , but luckily other fellow Fujifilm shooters do :).

So, you can find a video made by Andrei, that shows the difference between Fujifilm X-T4 firmware 1.02 and 1.03. He says:

  • Exposure changes a lot better than before, it’s not changing in steps anymore
  • he is happy that Fujifilm works on fixing the small problems the X-T4 has, because it is an amazing camera
  • he shot some clips in 24fps, some in 30fps and slowed down at 24fps in post to see exposure change better
  • he also shot at 60fps and higher frame rates, but at those frame rates it still does not work smooth [admin note: in my quick testings, I see the stepping still clearly at 100 fps and above]
  • at 60fps he shows how the exposure still works in steps, but in my eyes (fujirumors), it is actually smooth, then only shortly stops for moment, and then continues to go down smoothly. Much better than before, where you saw fast and hard steps. Maybe a further firmware down the road will also take away that very last pause at 60fps and higher frame rates
  • he says the exposure still clips when you zoom in and out
  • a good improvement for people who are vlogging
  • he hopes next comes face/eye detection improvement and addition of 4:2:2 internal

Well, happy to see Fujifilm finally addressing this issue.

Let’s Go FAST: First Leaked Images of Upcoming f/1.4 Lens for Fujifilm GFX Mount

Share

In terms of very fast lenses, Fujifilm is offering (or will offer soon):

If you want to go even faster, then you have to fo with manual focus lenses, more precisely:

However, I have received some images by a new source (thanks), of another ultra fast upcoming lens for the Fujifilm GFX system, with a maximum aperture of f/1.4. You can see the images above, mounted on the best camera of all time, the Fujifilm GFX50R.

I am trying to get more information about it, but for now, all I can say is:

  • 1.4 lens for GFX system
  • likely manual focus
  • it will be a wide-standard lens (wider than the Mitakon)

Curious for more? Then stay tuned on FujiRumors, and I will update you as soon as I can, since I am continuous talk with the source. ;)

Sony A7sIII vs Fujifilm X-T4: “Fujifilm X-T4 comes with Top-notch Features at a Much More Affordable Price”

Share

Maybe the news might have passed under the radar, overshadowed by the Fujifilm announcement of the Fujifilm EF-60 flash and the Fujifilm EF-W1 commander, which everybody talks about today.

But I’d like to dedicate a space to a new camera that has been announced today, just in case you didn’t know, and it’s called Sony A7sIII.

It’s a fantastic camera, mainly for video, and it’s basically Sony’s statement that you better do not mess with them, when it comes to full frame cameras with great video performance.

BHphoto has put up a comparison roundup, where they compare the Sony A7sIII with the following cameras:

Overall they talk very good about the new Sony A7sIII and it wins many comparisons overall, although it’s though to compare cameras, which, in some cases, serve a different purpose.

However, overall, one of the cameras that comes out best from this comparison, is the Fujifilm X-T4, because, as they write:

the X-T4 comes in with a top-notch feature set at a much more affordable price […]

It does take advantage of that sensor size to create a smaller, yet still super-capable stills and video system that comes in at a much more affordable price point.

Read the full comparison here.

This kind of underlines once again the strength of an APS-C system: the balance!

But we have already discussed the balance vs. compromise argument in this dedicated post.

Congratz Sony, it’s a wonderful camera. But also congratz to Fujifilm, for releasing such a well rounded package with the X-T4.
