Fujifilm released firmware updates for Fujifilm X-T4. [Note: in the original article I wrote also about X-A7 firmware, but that was the one released a few days ago, I removed that part now].
The phenomenon is fixed that the battery in the camera body cannot be charged by the bundled AC adapter when the USB POWER SUPPLY SETTING is changed to OFF from ON (default setting).
The phenomenon is fixed that repeated turning on and off a camera delays the set time.
Gordon from Cameralabs published the full Fujifilm X-T4 review.
I know many of you will probably see this in a hurry on their smartphones, so I will provide the full written summary below.
same form factor of X-T3
in terms of size, the biggest difference to X-T3 is the thickness, due to IBIS and more powerful battery
a bit heavier
more comfortable grip hold
controls look familiar to X-T3
movie mode now has its own switch
Fujifilm is gradually understanding the needs of videographers
now camera is much easier and practical when switching between stills and video
luckily it keeps the D-Pad
hard to press Q button accidentally, that’s good
articulating screen, a delight for vloggers
more rigid eye-cup
viewfinder has a boost option for clearer low light view
removable SD-card slot great if you work on a cage
headphone jack is gone, but you can adapt it via USB-C port
new battery is very welcome, rated for 500 shots
he exceeded the given battery life, by taking 550 shots using mechanical shutter and IBIS enabled and a few minutes with IBIS stabilized 4K video clips
he filmed 3.5 hours clips in 4K 25p with IBIS, with battery expiring 18 minutes and 40 seconds into the 4th clip
after the first clip, the X-T4 became very warm, but only became a little bit hotter as the test proceeded
at no point it overheated or became uncomfortable to hold
total of 109 minutes of 4K25p video on a single charge vs 62 minutes with X-T3
X-T4 IBIS is more effective on almost all lenses compared to X-H1
X-T4 is slimmer than X-H1
on of the best benefits of IBIS is having a stable view while composing your image with non stabilized lenses like the XF16-55mmF2.8, XF56mmF1.2 and XF90mmF2
he got sharp results at 1/5th of a second using XF16-55mmF2.8. Without IBIS he could have shot only at 1/80th of a second. That’s 4 stops of compensation (a bit less than what Fujifilm claims, but still great results)
IBIS + DIS (digital stabilization) applies 1.1x crop at all video formats, except for 4K@50/60p, where the crop is 1.29x
he does not notice any additional advantage using DIS
If you use IBIS with Boost mode (best used with static subjects), you see a small improvement over IBIS only. Applies no crop
impressive 15 fps mechanical shutter
quieter shutter than X-T3. It is incredible silent
eye autofocus does a good job, but maybe not quite as sticky as the latest Sony cameras, but certainly now amongst the best out there
no animal face/eye detection
Eterna bleach bypass is ideal for stylized video
annoying: the large color array (where you select your color temperature) can be navigated only with D-Pad (no joystick). It would have been better if one could use the joystick for faster selection
images have plenty of detail, but it’s the colors and tones that continue to be a highlight of owning an X series camera
X-T4 will be one of the last, if not the last model to use the X-Trans IV sensor
recording times: 30 minutes at 4K/30p and 20 minutes at 4K/50-60p
X-T4 support ExFAT (does not split longer video files in multiple clips)
ETERNA is a great allround use film simulation for video
during panning IBIS is easy to catching up on itself, delivering some jarring stumbling effect. To be fair, this effects also many other stabilized systems, but it is something to be aware of
walking while filming is more successful (compared to panning)
autofocus while filming is OK, but with occasional hunting or overshooting, and lacks the ultimate confidence of Sony and Canon latest systems
might not be the best in class AF in video, but it is still pretty good
overall the X-T4 is a compelling high-end option for vloggers
having 24o fps slow motion is rather impressive, when most rivals top out at 100 or 120 fps.
240 fps footage looks softer than 120 fps. Horizontal resolution is essential the same, but dramatic reduction in vertical resolution
Fujifilm Japan confirmed to him, that 200/240 fps use only about half of the vertical data
this is not an unusual technique, as lots of other cameras do the same at higher frame rates. Actually, few rivals even offer more than just about half of 240 fps
4K/60p quality is as good as his full frame 4K in his resolution tests.
4K/60p maintains sound
Fujifilm says the X-H line will continue
Gordon suspects the X-T4 will be the last body to use X-Trans IV sensor. But the X-Trans IV sensor is only 1.5 years old and delivers great results
the 6×6 X-Trans filter array makes it hard to implement pixel shift than the 2×2 Bayer pattern (which is what the GFX100 will get)
high end APS-C cost about the same of mid-range/budget full frame bodies. The Canon EOS RP costs less (even with lens) and the Canon R costs the same. But neither of those full frame cameras has IBIS, dual SD-Card slot nor 4K/60p video
Nikon Z6 and Sony A7III (no 4K/60) are priced a little bit higher, but still within reach of the X-T4
Personally Gordon would not trade a bigger sensor for the overall feature set of the X-T4 at least at this price point
Fujifilm enhanced a popular mode without compromising its charm
The Japanese store MapCameras published their top selling camera rankings for last month.
The Fujifilm X-T4 leads the pack, and we find other 3 Fujifilm in the top 10. I am surprised to see the Fujifilm X-H1 in there, not because it would not deserve that spot, but because it is discontinued on so hard to find anywhere.
Of course thet Mapcamera data is not representative for overall sales.
With that said, if big retailers share their sales data, it might not be representative for the overall market, but it can still give an approximate indication of what the market wants and how different markets react to different products.
So, down below is Mapcamera ranking for April 2020
