Nikon D7100 vs YI M1
The Nikon D7100 and the YI M1 are two digital cameras that were officially introduced, respectively, in February 2013 and September 2016. The D7100 is a DSLR, while the M1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D7100) and a Four Thirds (M1) sensor. The Nikon has a resolution of 24 megapixels, whereas the YI provides 20.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D7100 and the YI M1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Nikon D7100 and the YI M1. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The M1 can be obtained in two different colors (black, silver), while the D7100 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the YI M1 is considerably smaller (50 percent) than the Nikon D7100. Moreover, the M1 is substantially lighter (63 percent) than the D7100. It is worth mentioning in this context that the D7100 is splash and dust resistant, while the M1 does not feature any corresponding weather-sealing.
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 compare the optics available for the two cameras in the Nikon Lens Catalog (D7100) and the Micro Four Thirds Lens Catalog (M1). Mirrorless cameras, such as the M1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
The power pack in the M1 can be charged via the USB port, which can be very convenient when travelling.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
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 markedly lower price (by 71 percent) than the D7100, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D7100 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 D7100 has a native 3:2 aspect ratio, while the one in the M1 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24MP, the D7100 offers a higher resolution than the M1 (20.2MP), but the D7100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the M1) due to its larger sensor. However, the M1 is a much more recent model (by 3 years and 6 months) than the D7100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D7100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7100 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the YI M1 are 25.9 x 19.4 inch or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inch or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inch or 43.9 x 32.9 cm for excellent quality prints.
The Nikon D7100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the YI M1 are ISO 100 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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").

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, but the M1 provides a better video resolution than the D7100. It can shoot movie footage at 4K/30p, while the Nikon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D7100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Nikon D7100 and YI M1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D7100 has one, while the M1 does not. While the built-in flash of the D7100 is not very powerful, it can at times be useful as a fill-in light.
The Nikon D7100 and the YI M1 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the D7100 and the M1 write their files to SDXC cards. The D7100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M1 only has one slot. The D7100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M1 cannot take advantage of Ultra High Speed SD cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Nikon D7100 and YI M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D7100 has a microphone port, which is missing on the M1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The M1 is a recent model that features in the current product line-up of YI. In contrast, the D7100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D7100 was succeeded by the Nikon D7200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and YI websites.
So how do things add up? Is there a clear favorite between the Nikon D7100 and the YI M1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Nikon D7100:
- More detail: Offers more megapixels (24 vs 20.2MP) with a 11% higher linear resolution.

If the count of relative strengths (bullet points above) is taken as a measure, the D7100 is the clear winner of the match-up (16 : 10 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Nikon D7100 and the YI M1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the D7100 and the M1 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.
The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
