Canon 77D vs Pentax MX-1
The Canon EOS 77D and the Pentax MX-1 are two digital cameras that were officially introduced, respectively, in February 2017 and January 2013. The 77D is a DSLR, while the MX-1 is a fixed lens compact. The cameras are based on an APS-C (77D) and a 1/1.7-inch (MX-1) sensor. The Canon has a resolution of 24 megapixels, whereas the Pentax provides 12 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 Canon EOS 77D and the Pentax MX-1? 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 physical size and weight of the Canon 77D and the Pentax MX-1 are illustrated 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 size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax MX-1 is considerably smaller (43 percent) than the Canon 77D. In this context, it is worth noting that neither the 77D nor the MX-1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the MX-1 has a lens built in, whereas the 77D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 77D and their specifications in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The MX-1 was launched at a lower price than the 77D, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 77D features an APS-C sensor and the Pentax MX-1 a 1/1.7-inch sensor. The sensor area in the MX-1 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.5. The sensor in the 77D has a native 3:2 aspect ratio, while the one in the MX-1 offers a 4:3 aspect.
With 24MP, the 77D offers a higher resolution than the MX-1 (12MP), but the 77D nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.89μm for the MX-1) due to its larger sensor. Moreover, the 77D is a much more recent model (by 4 years and 1 month) than the MX-1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 77D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 77D for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Pentax MX-1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The 77D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 77D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Pentax MX-1 are ISO 100 to ISO 12800 (no boost).
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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. Of the two cameras under review, the 77D provides substantially higher image quality than the MX-1, with an overall score that is 29 points higher. This advantage is based on 3.2 bits higher color depth, 2 EV in additional dynamic range, and 2.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 77D provides a higher frame rate than the MX-1. It can shoot video footage at 1080/60p, while the Pentax is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 77D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the MX-1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 77D and Pentax MX-1 along with similar information for a selection of comparators.

One feature that is present on the 77D, but is missing on the MX-1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The 77D has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the MX-1 does not have a selfie-screen.
The Canon 77D has 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 77D and the MX-1 write their files to SDXC cards. The 77D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the MX-1 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 Canon EOS 77D and Pentax MX-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 77D has a hotshoe, while the MX-1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the 77D and the MX-1 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Canon and Pentax. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.
So what is the bottom line? Is the Canon 77D better than the Pentax MX-1 or vice versa? The listing below highlights the relative strengths of the two models.

- Ready to shoot: Comes with an integrated lens, while the 77D requires a separate lens.
- More compact: Is smaller (122x61mm vs 131x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the 77D).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been around for much longer (launched in January 2013).
If the count of relative strengths (bullet points above) is taken as a measure, the 77D is the clear winner of the match-up (24 : 7 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Canon 77D and the Pentax MX-1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 77D or the MX-1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
