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 HX99 was somewhat cheaper (by 10 percent) than the MX-1 at launch, but both cameras fall into the same price category. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant 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. 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 Pentax MX-1 features a 1/1.7-inch sensor and the Sony HX99 a 1/2.3-inch sensor. The sensor area in the HX99 is 35 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a smaller sensor, the HX99 offers a higher resolution of 18 megapixels, compared with 12 MP of the MX-1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.25μm versus 1.89μm for the MX-1). However, it should be noted that the HX99 is much more recent (by 5 years and 7 months) than the MX-1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the HX99 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony HX99 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX99 for good quality output (200 dots per inch) amounts to 24.5 x 18.4 inches or 62.2 x 46.6 cm, for very good quality (250 dpi) 19.6 x 14.7 inches or 49.7 x 37.3 cm, and for excellent quality (300 dpi) 16.3 x 12.2 inches or 41.5 x 31.1 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 Pentax MX-1 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Sony Cyber-shot DSC-HX99 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
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.
| DXO |

|12.||Olympus E-PL2||Four Thirds||12.2||4032||3024||720/30p||21.4||10.2||573||55|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the HX99 provides a better video resolution than the MX-1. It can shoot movie footage at 4K/30p, 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 HX99 has an electronic viewfinder (638k dots), which can be very helpful when shooting in bright sunlight. In contrast, the MX-1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Pentax MX-1 and Sony HX99 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The HX99 has a touchscreen, while the MX-1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The HX99 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the MX-1 does not have a selfie-screen.
Both the MX-1 and the HX99 have zoom lenses built in. The MX-1 has a 28-112mm f/1.8-2.5 optic and the HX99 offers a 24-720mm f/3.5-6.4 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Pentax. The MX-1 offers the faster maximum aperture.
The MX-1 writes its imaging data to SDXC cards, while the HX99 uses SDXC or Memory Stick PRO Duo cards. The HX99 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 Pentax MX-1 and Sony Cyber-shot DSC-HX99 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the HX99 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the MX-1 does not provide wifi capability.
The HX99 is a recent model that features in the current product line-up of Sony. In contrast, the MX-1 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the MX-1 from Pentax. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax and Sony websites.
So how do things add up? Is the Pentax MX-1 better than the Sony HX99 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Pentax MX-1:

If the count of relative strengths (bullet points above) is taken as a measure, the HX99 is the clear winner of the contest (18 : 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. 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the MX-1 or the HX99. 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 adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
