YI M1 versus Fujifilm X-T20
The YI M1 and the Fujifilm X-T20 are two digital cameras that were officially introduced, respectively, in September 2016 and January 2017. Both the M1 and the X-T20 are mirrorless interchangeable lens cameras that are based on a Four Thirds (M1) and an APS-C sensor. The YI has a resolution of 20.2 megapixel, whereas the Fujifilm provides 24 MP.
An illustration of the physical size and weight of the YI M1 and the Fujifilm X-T20 is provided in the side-by-side display below. 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 M1 – 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 Fujifilm X-T20 is notably larger (34 percent) than the YI M1. Moreover, the X-T20 is substantially heavier (36 percent) than the M1. In this context, it is worth noting that neither the M1 nor the X-T20 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 Micro Four Thirds Lens Catalog (M1) and the Fujinon X Lens Catalog (X-T20). 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M1 was launched at a markedly lower price (by 61 percent) than the X-T20, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the YI M1 features a Four Thirds sensor and the Fujifilm X-T20 an APS-C sensor. The sensor area in the X-T20 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the M1 has a native 4:3 aspect ratio, while the one in the X-T20 offers a 3:2 aspect.
With 24MP, the X-T20 offers a higher resolution than the M1 (20.2MP), but the X-T20 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.34μm for the M1) due to its larger sensor. Moreover, the X-T20 is a somewhat more recent model (by 4 months) than the M1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X-T20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the X-T20 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the YI M1, the Fujifilm X-T20, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the M1 and the X-T20 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The X-T20 replaced the earlier Fujifilm X-T10, while the M1 does not have a direct predecessor.
So what is the bottom line? Is there a clear favorite between the YI M1 and the YI M1? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the YI M1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (114x64mm vs 118x83mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 102g or 27 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (450 versus 350) on a single battery charge.
- More affordable: Was introduced into a lower priced category (61 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in September 2016).
Arguments in favor of the Fujifilm X-T20:
- More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More modern: Was introduced somewhat (4 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the X-T20 emerges as the winner of the match-up (8 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the M1 and the X-T20 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
