DxOMark Mobile
Overview
The Moto Z Force Droid also offers consistently good performance across both stills and video, achieving a Photo sub-score of 87 and Video sub-score of 86, with the overall result weighted in favor of the Photo score. Exposures are generally very good across a range of different lighting conditions, including good dynamic range; well-balanced, high-contrast exposures, thanks to its Auto HDR mode; and pleasant color with neutral white balance. The high-resolution sensor also enables 4K video capture, with movies continuing to offer excellent levels of detail, particularly in bright light. Exposure and stabilization are also strong points, with the Moto Z Force Droid rendering both pleasant and smooth videos.
The Moto Z Force Droid’s high-resolution 21Mp sensor captures nice exposures with strong, bold color and some of the best detail preservation we’ve seen for smartphones.
Outdoor pictures with superb detail and minimal noise
Shooting outdoors and in bright light conditions, the Moto Z Force Droid produced an excellent set of test images, with good exposure, neutral white balance, excellent detail with well-controlled noise, and vivid color. When triggered, the built-in Auto HDR proved very successful. In tricky high-contrast scenes, skies were well exposed, with good highlight detail; and despite slightly clipped shadows, the overall exposure was very pleasing. On overcast days, HDR exposures were excellent, too, with detail in the sky and excellent processing in the darker areas, ensuring good detail with very little visible noise or color shading.
We observed the odd exposure failure in very bright scenes, with some over exposure and blown-out highlights, but such failure was a rare occurrence. The Moto Z Force Droid’s 21Mp sensor captures outstanding levels of fine detail — in fact, some of the most intricate results we’ve seen from a smartphone.
In bright light conditions, very fine details, such as the mesh on the air vents, shows the extent of the resolution possible, with almost no moiré visible in these high-frequency patterns. Outdoors, noise reduction is very good, too. In blocks of uniform color, such as the blue sky, a fine luminance noise is just visible, but it’s not offensive and is not visible at all in more intricate areas of the picture. Good white balance ensures natural results, with bold, well-saturated color; and although we observerd some exposure and white balance irregularities, the degree of variation between results was well within acceptable parameters.
On bright days, Auto HDR mode does an excellent job of maintaining highlight details, and while some of the blacks are clipped, the exposure remains very pleasant overall.
On a more overcast day, we recorded high levels of shadow detail under the bridge with no visible color shading or noise; excellent detail in the tower and bridge is also evident.
We recorded some exposure failures, including this over-exposed scene, but this was an infrequent occurrence with the Moto Z Force Droid.
Great indoor photos even in extreme low light
Indoors, the Moto Z Force Droid’s f/1.8 lens aperture and Optical Image Stabilization (OIS) help produce some very successful low-light results. In extreme low light (5 Lux), images are a little under-exposed, but far from the worst we’ve seen, remaining very usable with nice (if not bold) color. Even in extreme low light, the bright lens aperture and OIS allow the Moto Z Force Droid to use exposure settings that help maintain better image quality. The maximum ISO sensitivity employed was a fairly low ISO 2000, compared to ISO 3200, which is often used. You should still expect some loss of fine detail in low light conditions, but results are very commendable nonetheless.
The Moto Z Force Droid also uses a fairly slow 1/10 shutter speed, but thanks to the OIS system, using good technique when shooting hand-held make sharp results possible. Under brighter 10 and 20 Lux light sources, the shutter speed remains at 1/10 sec, but the Moto Z Force Droid uses lower ISO sensitivities for both cleaner and more detailed low-light pictures. At 100 and 500 Lux, both a lower ISO setting and a faster 1/30 sec shutter speed ensure the excellent sharp, detailed, well-exposed shots we saw during outdoor testing.
We observed some slight irregularities in noise, exposure, detail, and color when taking consecutive low light shots, but the variation wasn’t overly concerning, and we often achieved good results.
Under an extreme lo- light 5 Lux light source, images are a little under-exposed, but still usable; and the f/1.8 lens and OIS system help reduce noise and produce sharper results.
Exposures are brighter under a 100 Lux light source, with better color; a low ISO 640 sensitivity and 1/30 sec shutter speed ensures sharp images with virtually no visible noise.
Details: Explaining the scores
Exposure and Contrast (89)
One of its best category scores, the Moto Z Force Droid produces well-exposed images in all conditions with very few failures. HDR exposures in both bright and overcast conditions are very successful, recording good highlight detail in most cases, and good shadow detail with no visible color shading or excessive noise. Indoor exposures are excellent, too, thanks to the f/1.8 lens ensuring bright exposures with low ISO sensitivities even in extreme lowlight, and the OIS system helps achieve sharp shots even when using slow shutter speeds.
Successful HDR exposures render a full range of tones, with good shadow detail that displays no visible color shading and little visible noise in areas with high levels of detail.
Color (83)
The Moto Z Force Droid achieves a very acceptable score of 83 for color, thanks to accurate white balance, vivid hues, and barely-visible color shading in outdoor shots. Some color shading is visible under extreme low-light tungsten light sources, with a pink cast in the center shifting to green at the edges.
Neutral white balance on outdoor exposures display accurate color with pleasant hues and no signs of color shading.
Autofocus (91)
An outstanding result for autofocus means that you can be assured of fast and reliable focusing in most conditions when shooting stills or videos with the Moto Z Force Droid. Autofocus is both accurate and repeatable in all conditions, and although video focus is a little slower in low light to converge as you change scenes, it remains very acceptable.
Texture (88) and Noise (88)
Producing some of the most detailed smartphone pictures we’ve seen, the Moto Z Force Droid’s 21Mp sensor does an excellent job of maintaining detail while minimizing noise. Very intricate details are preserved in bright light, and only a fine luminance noise is visible in blocks of uniform color. In low light, the results were a little more inconsistent, but with good handling and capture technique, both sharp and nicely textured images with acceptable levels of noise were achievable. A sequence of images captured in low light using continuous burst mode displayed significantly more noise and less detail, so this feature is probably best avoided.
