Fujifilm X-A3 versus YI M1

The Fujifilm X-A3 and the YI M1 are two digital cameras that were announced, respectively, in August 2016 and September 2016. Both the X-A3 and the M1 are mirrorless interchangeable lens cameras that are based on an APS-C (X-A3) and a Four Thirds (M1) sensor. The Fujifilm has a resolution of 24 megapixel, whereas the YI provides 20.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Fujifilm X-A3 vs YI M1

An illustration of the physical size and weight of the Fujifilm X-A3 and the YI M1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the X-A3 – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the YI M1 is notably smaller (7 percent) than the Fujifilm X-A3. Moreover, the M1 is markedly lighter (17 percent) than the X-A3. In this context, it is worth noting that neither the X-A3 nor the M1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Fujinon X Lens Catalog (X-A3) and the Micro Four Thirds Lens Catalog (M1). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The M1 was launched at a somewhat lower price (by 13 percent) than the X-A3, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

 

Sensor comparison: Fujifilm X-A3 vs YI M1

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-A3 features an APS-C sensor and the YI M1 a Four Thirds sensor. The sensor area in the M1 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X-A3 has a native 3:2 aspect ratio, while the one in the M1 offers a 4:3 aspect.

Fujifilm X-A3 and YI M1 sensor measures

With 24MP, the X-A3 offers a higher resolution than the M1 (20.2MP), but the X-A3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.34μm for the M1) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

X-A3 versus M1 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the M1 provides a better video resolution than the X-A3. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/60p.

 

Feature comparison: Fujifilm X-A3 vs YI M1

Apart from body and sensor, cameras can and do differ across a range of features. The X-A3 and the M1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The following table reports on some other key feature differences and similarities of the Fujifilm X-A3, the YI M1, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One difference between the cameras concerns the presence of an on-board flash. The X-A3 has one, while the M1 does not. While the build-in flash of the X-A3 is not very powerful, it can at times be useful as a fill-in light.

Both the X-A3 and the M1 write their imaging data to SDXC cards.

Review summary: Fujifilm X-A3 vs YI M1

So how do things add up? Which of the two cameras – the Fujifilm X-A3 or the YI M1 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Fujifilm X-A3:

  • More detail: Offers more megapixels (24 vs 20.2MP) with a 11% higher linear resolution.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.

ilogo

Reasons to prefer the YI M1:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Less heavy: Has a lower weight (by 58g or 17 percent) and is thus easier to take along.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was released into a lower priced segment (13 percent cheaper at launch).

If the count of relative strengths (bullet points above) is taken as a measure, the X-A3 comes out slightly ahead of the M1 (5 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

X-A3 05:04 M1

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X-A3 or the M1 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
