Fujifilm X-T4 Review

May 5, 2020 | Tim Coleman |

Image Quality

All of the sample images in this review were taken using the 26.1 megapixel Raw + Fine JPEG setting, which gives an average image size of around (a whopping) 55Mb and 10Mb respectively.

With an identical sensor to the Fujifilm X-T3, the X-T4 boasts outstanding image quality, which today 18-months on remains class-leading.

The native sensitivity range is ISO 160 to ISO 12,800, which can be expanded to ISO 80 to ISO 51,200. In JPEG images there is no visible sign of noise all the way up to ISO 6400, which is mightily impressive for an APS-C sensor.

The impact of noise at ISO 12,800 is seen through a minor colour desaturation and smudged detail in shadow areas. Of course the extended high settings of ISO 25,600 and ISO 51,200 progressively exhibit more noise but those images are still useable.

We like the application of noise reduction in those JPEG images - it's not too heavy handed so as to overly smudge detail. In RAW files where no noise reduction is applied, noise is more evident but images still look pretty clean up to ISO 12,800.

Yes, we would happily shoot the entire native ISO range in RAW and JPEG and it's not often that we could say that about a camera.

Elsewhere, we love the Fujifilm colour science. The sensor of the XT4 uses a different colour array to other brands and the results are lovely, especially when you factor in the choice of Fujifilm’s film simulation for different colour effects. Provia is the standard mode and we are partial to the Eterna Cinema mode.

With an excellent sensor that provides crisp images full of detail come day or night, fast and reliable AF, class-leading continuous high speed shooting, quick handling and improved stabilisation, there is little that the Fuji XT4 cannot handle.

Noise

There are 11 ISO settings available for the Fujifilm X-T4 for RAW and JPEG files. Here are some 100% crops which show the levels of noise for each ISO setting.

File Quality

The Fujfilm X-T4 shoots in RAW and JPEG with two quality settings; Fine and Normal . Here are 100% crops of those three options with the files size shown in brackets.

Fine (13.7Mb) (100% Crop) Normal (8.37Mb) (100% Crop)

Night

Set the shutter speed dial to its T position ( Time) and shutter speeds up to 15 minutes are available, plus there is a bulb setting for even longer shutter speeds. Combined with such a good control over noise, the X-T4 is an excellent night shooter.

Dynamic Range

A dynamic range (DR) boost is always on, with a choice between auto, 100%, 200% and 400%. We taken have identical images going through this range of settings and the visible difference of detail in the extreme shadow and highlights areas is actually rather subtle. As such, for the most part we kept DR in the auto setting.

There is also a HDR option with options of Auto, 200%, 400%, 800% and 800%+. Multiple images are recorded and combined into one final image of greater dynamic range. With both IBIS and OIS active and rapid multi-frame capture, it is entirely possibly to use the HDR mode handheld (depending on your shutter speed).

Film Simulations

There is a new film simulation mode on the block; Eterna Bleach Bypass, offering a high contrast desaturated look. Of course, colour profile preferences are subjective and also down to what is in the picture. This new mode would work particularly well for male portraits and gritty urban scenes.

In addition to Eterna Bleach Bypass there are another 11 film simulation modes, two of which (Acros and Black & White) have several sub-options. Below is an example of these 12 film simulation modes. For us, the addition of new film simulation modes are a nice extra but no reason to upgrade a camera.

Advanced Filters

Another setting on the drive mode dial is Advanced Filter. We suspect these filters will remain unused by most X-T4 owners. What you have are 13 different filter effects (six of which are partial colour effects) that are visible on screen when the mode is active. From Toy camera to High-Key and Low-Key, we've included these 13 effects below.
