Rất chân thành cảm ơn các bạn p/s : Chỉ có nhu cầu máy nhỏ gọn và tiện dụng, không thích dòng DSLR The Panasonic Lumix DMC-LX7 and the Sony Alpha NEX-5R are two digital cameras that were announced, respectively, in July 2012 and August 2012. The LX7 is a fixed lens compact, while the NEX-5R is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (LX7) and an APS-C (NEX-5R) sensor. The Panasonic has a resolution of 10 megapixels, whereas the Sony provides 16 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 Panasonic Lumix DMC-LX7 and the Sony Alpha NEX-5R? 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. Body comparisonThe physical size and weight of the Panasonic LX7 and the Sony NEX-5R 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 width, height and depth measures are rounded to the nearest millimeter. The LX7 can be obtained in two different colors (black, white), while the NEX-5R is also available in two color-versions, but different ones (black, silver). If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-5R is notably smaller (13 percent) than the Panasonic LX7. In this context, it is worth noting that neither the LX7 nor the NEX-5R are weather-sealed. The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX7 has a lens built in, whereas the NEX-5R 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 NEX-5R and their specifications in the Sony E-Mount Lens Catalog. The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras 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 LX7 was launched at a lower price than the NEX-5R, 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. Sensor comparisonThe 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 , and richer 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 in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses. Of the two cameras under consideration, the Panasonic LX7 features a 1/1.7-inch sensor and the Sony NEX-5R an APS-C sensor. The sensor area in the NEX-5R is 769 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 1.5. The sensor in the LX7 has a native 4:3 aspect ratio, while the one in the NEX-5R offers a 3:2 aspect. The LX7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution. With 16MP, the NEX-5R offers a higher resolution than the LX7 (10MP), but the NEX-5R nevertheless has larger individual pixels ( of 4.78μm versus 2.05μm for the LX7) 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. The resolution advantage of the Sony NEX-5R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-5R for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.6 x 27.6 cm. The corresponding values for the Panasonic LX7 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints. The Panasonic Lumix DMC-LX7 has a native sensitivity range from ISO 80 to ISO 6400, which can be extended to ISO 80-12800. The corresponding ISO settings for the Sony Alpha NEX-5R are ISO 100 to ISO 25600 (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 consideration, the NEX-5R offers substantially better image quality than the LX7 (overall score 28 points higher). The advantage is based on 3 bits higher color depth, 1.4 EV in additional dynamic range, and 2.6 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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 LX7 provides a higher frame rate than the NEX-5R. It can shoot video footage at 1080/60p, while the Sony is limited to 1080/60i. Feature comparisonBeyond body and sensor, cameras can and do differ across a range of features. The LX7 and the NEX-5R 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. However, optional viewfinders – the DMW-LVF2 for the LX7 and the FDA-EV1S for the NEX-5R – are available as accessories. The table below summarizes some of the other core capabilities of the Panasonic LX7 and Sony NEX-5R in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The LX7 has one, while the NEX-5R does not. While the built-in flash of the LX7 is not very powerful, it can at times be useful as a fill-in light. The NEX-5R 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 LX7 does not have a selfie-screen. The Panasonic LX7 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. The LX7 writes its imaging data to SDXC cards, while the NEX-5R uses SDXC or Memory Stick PRO Duo cards. Connectivity comparisonFor 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 Panasonic Lumix DMC-LX7 and Sony Alpha NEX-5R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NEX-5R offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the LX7 does not provide wifi capability. Both the LX7 and the NEX-5R have been discontinued, but can regularly be found used on ebay. The LX7 was replaced by the Panasonic LX10, while the NEX-5R was followed by the Sony NEX-5T. Further information on the features and operation of the LX7 and NEX-5R can be found, respectively, in the Panasonic LX7 Manual (free pdf) or the online Sony NEX-5R Manual. Review summarySo what conclusions can be drawn? Is the Panasonic LX7 better than the Sony NEX-5R or vice versa? The listing below highlights the relative strengths of the two models. Reasons to prefer the Panasonic Lumix DMC-LX7:
Advantages of the Sony Alpha NEX-5R:
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-5R is the clear winner of the contest (11 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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. LX7 07:11 NEX-5R How about other alternatives? Do the specifications of the Panasonic LX7 and the Sony NEX-5R place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 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 LX7 or the NEX-5R. 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. Expert reviewsThis 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 (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. 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 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. Other camera comparisonsDid this review help to inform your camera decision process?
