Fujifilm X-T4 vs Sony A7R IV Comparison with Fujifilm Manager Warwick Williams

Josh from Georges compares two cameras the Fujifilm X-T4 and the Sony A7R IV to see what they are like for both stills and video.

The curious thing about this comparison, is that he is assisted by Warwick Williams from Fujifilm Australia.

The gear used, beyond the Fujifilm X-T4 (26 MP) and the Sony A7rIV (61 MP):

Of course, when zooming in a lot into the image, the 61 megapixel have an advantage in terms of resolution. But I guess if resolution is what you need, then why just be happy with 61 MP when you can get 102 megapixel with the Fujifilm GFX100 ;).

Then they compared the depth of field between the XF56mmF1.2 and the FE85mmF1.4 and the Sony blurs the background a bit more. Warwick says he should have used the XF56mmF1.2 APD version to get results even closer to the ones you get with the Sony 85mmF1.4.

Let me add a comment: get the upcoming Fujinon XF50mmF1.0 if you really want the ultimate background blur.

A bit more dynamic range for the Sony, but the APS-C sensor hold up very well.

APS-C systems are generally smaller and more affordable.

Georges ends up saying that after looking at the samples, there is a difference between FF and APS-C, but it is a lot smaller than he would have expected.

Warwick ends up saying that Fujifilm wants to keep the APS-C system smaller and lighter, and for that purpose APS-C is better as it allows for smaller lenses. He also speaks for X-Trans, which he says has advantages over Bayer (which FujiRumors explained here, but we also talked about disadvantages in the same post).

Warwick concludes that “smaller and lighter means you are going to use it also more“.

George ends up saying, it all comes down to personal preferences as each system as its Pros and Cons (which we highlighted in this article).

Nobody talks about the price difference ;).

Fuji Guy Billy Interview

Fuji Guy Billy joined the Fujilove podcast. For those of you, who are right now on the road or at work and you can’t listen to it all at iTunes, Stitcher or on fujilove, here are the key points:

Fujinon X Mount Lenses

Fujifilm X100, X-E3, X-T20 and X-T3

  • Fujifilm X100 was the game changer and started the X series success
  • When developing the X100, Fujifilm wondered who is going to buy a fixed lens camera at this price point, but it turned out to be a success
  • Fujifilm X-T3 is balance of size, weight and quality in a good price point, but for Billy even the X-T3 is big
  • Billy’s go-to camera is the Fujifilm X-E3, paired with XF35mmF2, XF23mmF2 and occasionally the XF50mmF2 because of portability
  • Fujifilm X-T20 with no joystick is a dealbreaker for him

Fujifilm X-H1

  • Fujifilm X-H1 latest firmware introduced lots of improvements and the new lower price makes it very tempting
  • The Fujifilm X-H1 maybe has been misunderstood by the market. It had a lot of new video features, so people considered it more a video camera. But it is also a better and more robust camera, and facilitates handling of bigger lenses. For Professionals weight is sometimes not a problem, but more durability. That’s why Fujifilm launched the Fujifilm X-H1. It should also appeal to DSLR customers, who were on the fence of switching to mirrorless. IBIS is quite nice also for photography, especially in low light
  • Shutter has an S1 (half press) and S2 (full contact to release shutter) position. Regarding the Fujifilm X-H1, you can contact your Fujifilm service and see if they have an option to adjust the S1 and S2 position to your taste (low, medium or high). There might be a charge for that service, depending on your country


  • Fujifilm wanted to make an excellent IBIS system, and it is one of the best on the market. But the size of the system was too big to put it into other X-series cameras. At this moment, it can’t fit in other cameras, but hopefully one day IBIS can be designed smaller and make it fit on other cameras

Fujinon G Mount Lenses

  • Fujinon GF 50mm f/3.5 coming in 2019 and Fujinon GF 45-100mm f/4 in 2020
  • Fujinon GF 100-200mm f/5.6 R LM OIS WR: If you look to move into medium format, you don’t have many lenses initially to choose from, so zoom lenses can cover various focal lengths. The GF100-200 is compatible with teleconverter. It’s a little bit heavier, but very sharp. At that focal length with medium format sensor, you can isolate your subject very well
