Vâng. Mới nghe tên thì thấy khác nhau một trời một vực. Máy Canon đắt gấp đôi tiền (khoảng 24 triệu). Dòng này của Canon thì khỏi nói rồi, anh em ai cũng biết. Còn em Sony, em chỉ sợ nó ít người chơi, không biết chụp chiếc thế nào. Sợ là mua về chụp chán quá lại muốn bán đi để lên đời Canon, lúc đấy chả ai thèm mua, bán lại mất giá thì phí. Show Các bác giúp em chọn nhé. Từ nay đến cuối năm em định mua máy rồi. Cảm ơn các bác. EOS 40D là chiếc máy ảnh mới nhất của dòng máy ảnh số SLR của hãng Canon.

The 40D is a DSLR, while the NEX-5 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 10.1 megapixels, whereas the Sony provides 14 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 40D and the Sony Alpha NEX-5? 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 side-by-side display below illustrates the physical size and weight of the Canon 40D and the Sony NEX-5. 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 size dimensions are rounded to the nearest millimeter. The NEX-5 can be obtained in two different colors (black, silver), while the 40D 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 Sony NEX-5 is considerably smaller (58 percent) than the Canon 40D. Moreover, the NEX-5 is substantially lighter (65 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the NEX-5 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (40D) and the Sony E-Mount Lens Catalog (NEX-5). Mirrorless cameras, such as the NEX-5, 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. Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the NEX-5 can take 330 images on a single charge of its NP-FW50 power pack. The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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. Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The NEX-5 was launched at a markedly lower price (by 46 percent) than the 40D, 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.
Sensor comparisonThe 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 , and richer 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 in order to 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. Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-5 is 10 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (40D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2. With 14MP, the NEX-5 offers a higher resolution than the 40D (10.1MP), but the NEX-5 has smaller individual pixels ( of 5.11μm versus 5.73μm for the 40D). Yet, the NEX-5 is a much more recent model (by 2 years and 8 months) than the 40D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. The resolution advantage of the Sony NEX-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-5 for good quality output (200 dots per inch) amounts to 23 x 15.3 inches or 58.3 x 38.8 cm, for very good quality (250 dpi) 18.4 x 12.2 inches or 46.7 x 31 cm, and for excellent quality (300 dpi) 15.3 x 10.2 inches or 38.9 x 25.9 cm. The corresponding values for the Canon 40D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints. The Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Sony Alpha NEX-5 are ISO 200 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 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"). Of the two cameras under consideration, the NEX-5 has a markedly higher DXO score than the 40D (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.099999999999998 bits higher color depth, 0.9 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. 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. The NEX-5 indeed provides for movie recording, while the 40D does not. The highest resolution format that the NEX-5 can use is 1080/60i.
Feature comparisonApart from body and sensor, cameras can and do differ across a range of features. For example, the 40D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-5 relies on live view and the rear LCD for framing. That said, the NEX-5 can be equipped with an optional viewfinder – the FDA-SV1. The adjacent table lists some of the other core features of the Canon 40D and Sony NEX-5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 40D has one, while the NEX-5 does not. While the built-in flash of the 40D is not very powerful, it can at times be useful as a fill-in light. The NEX-5 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 40D does not have a selfie-screen. The 40D writes its imaging data to Compact Flash cards, while the NEX-5 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 Canon EOS 40D and Sony Alpha NEX-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 40D (unlike the NEX-5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera. Both the 40D and the NEX-5 have been discontinued, but can regularly be found used on ebay. The 40D was replaced by the Canon 50D, while the NEX-5 was followed by the Sony NEX-5N. Further information on the features and operation of the 40D and NEX-5 can be found, respectively, in the Canon 40D Manual (free pdf) or the online Sony NEX-5 Manual.
Review summarySo what is the bottom line? Is the Canon 40D better than the Sony NEX-5 or vice versa? A synthesis of the relative strong points of each of the models is listed below. Advantages of the Canon EOS 40D:
Arguments in favor of the Sony Alpha NEX-5:
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-5 is the clear winner of the contest (12 : 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 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. 40D 07:12 NEX-5 How about other alternatives? Do the specifications of the Canon 40D and the Sony NEX-5 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 40D and the NEX-5 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. Expert reviewsThis 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], 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 above review scores should be interpreted 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
