Test Samsung Galaxy Z Fold 4 : des retouches discrètes, mais sans faux-pli

Test Samsung Galaxy Z Fold 4 : des retouches discrètes, mais sans faux-pli

Unlike the Z Flip 4, which retains its predecessor’s photoblock on paper, the Z Fold 4 breaks with its predecessor. It is inspired by the Galaxy S22 and S22 +, offering a main module with a 50-megapixel sensor, and not 12-megapixel. It is accompanied by an ultra-wide-angle module with a 12-megapixel sensor, and another with a telephoto lens and a 10-megapixel sensor. A versatile set.

Wide-angle module: 50 megapixels, f/1.8, eq. 24mm

Who says very defined sensor also says pixel bonding. Small quibble: A walk through the details of the shots obtained shows that instead of 12.5 Mpx shots, Samsung downsized their images to 12 million dots. We compare the results obtained with those of an Oppo Find X5 Pro, slightly less expensive than the Fold 4, but also equipped with a 50 Mpx main module.

If the exposure is correct and the interpretation natural, we regret a smoothing of certain textures, such as that of the book cover or cartography; the effect was quite comparable on the Galaxy S22. Oppo’s model offers superior sharpness. Let’s add that the Fold 4’s shots lack sharpness in the periphery, which we noticed during all our tests. However, the image pleases the eye with its rich colorimetry and software processing that takes care of the contours of small elements.

Same observation at night, where however the difference with the Oppo model is much smaller. Where the Galaxy S22 chose to accentuate contrasts, for a rendering that lacks naturalness, the Z Fold 4 favors smoothness of treatment, but at the cost of visible smoothing. It still performs much better than the Galaxy Z Fold 3 from last year.

50 megapixel mode

The situation changes very little in 50-megapixel mode. Textures are softened and image outlines are blurred. If during the day this mode is justified when cropping is needed, it is not relevant in low light conditions.

Ultra wide angle module: 12 megapixels, f/2.2, eq. 12mm

The difference in processing is visible between the Galaxy S22 Ultra and the Galaxy Z Fold 4, both of which share a 12-megapixel ultra-wide module. The foldable smartphone’s shots are less noisy, but by limiting the noise, the smartphone opts for more smoothing. There is also some distortion and blurring in the corners of the image.

At night, the exposure chosen by the Z Fold 4 is more convincing, and the resulting colorimetry is more accurate. But sharpness is not enough for the image to really convince.

Telephoto module: 10 megapixels, f/2.4, eq. 67mm

The third and last photographic module included in the Galaxy Z Fold 3 consists of a 10-megapixel sensor associated with a telephoto lens that offers the equivalent of a zoom close to 3x (2.8x). The Galaxy Z Flip was based on a 12-megapixel sensor (2x zoom). If the newcomer has a less defined sensor, its optics offer higher magnification.

Quite convincing during the day, this module has the merit of capturing a sharp image even in the periphery, with a high level of detail and bright colors. However, the drop in definition separating the Z Fold 3 and Z Fold 4 is visible when you reframe the image: sharpness is less on the Z Fold 4, with the same area viewed.

At night, the smartphone simply crops an image captured with its main sensor. Difficult in these conditions to compensate by means of a simple software processing the lack of captured elements. The images, whose details lack precision, are unfortunately not very useful.

Front module, portrait and video mode

Rather than the 4-megapixel module found inside the Fold 4, under its screen, and whose results are too little detailed to be really usable, it is better to use the 10-megapixel sensor housed in the outer screen of the smartphone to take selfies. These are a bit too polished, but well exposed and appealing to the eye. The most demanding can also use the option offered when the screen is folded, that is, open the Fold and use the main module, always for selfies, while the Cover Display shows a preview of the image. If the grip is less easy for a self-portrait, the quality is better! Note in passing that the smartphone offers an effective portrait mode, as is often the case with Samsung, with fairly precise cropping. The 3x portrait capture mode is also the most detailed and natural; unwieldy in selfie mode, unless you put the Fold 4 on a pole! —, allows you to get beautiful photos of your loved ones.

On the video side, the Z Fold 4 lets you shoot up to 8K at 24fps. Remember, however, that the internal storage of the smartphone is not expandable, it is not necessarily useful to systematically use this definition, which does not support the electronic stabilization added by Samsung. It is reserved for Full HD (at 30 or 60 fps) and is effective. As is often the case with Koreans, it is possible to successfully switch from wide to ultra wide or telephoto during shooting, and when viewing the shooting area of ​​the other modules in thumbnail form (in “Director’s View” mode “). In short, Samsung offers a completely complete video experience here.
