Canon 50D vs 5D Mark II

The Canon EOS 50D and the Canon EOS 5D Mark II are two digital cameras that were officially introduced, respectively, in August 2008 and September 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (50D) and a full frame (5D Mark II) sensor. The 50D has a resolution of 15.1 megapixels, whereas the 5D Mark II provides 21 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 50D and the Canon EOS 5D Mark II? 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 comparison

An illustration of the physical size and weight of the Canon 50D and the Canon 5D Mark II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 Canon 5D Mark II is notably larger (10 percent) than the Canon 50D. Moreover, the 5D Mark II is slightly heavier (3 percent) than the 50D. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 (as in the 5D Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (50D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 50D gets 800 shots out of its BP-511A battery, while the 5D Mark II can take 850 images on a single charge of its LP-E6 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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 50D was launched at a markedly lower price (by 63 percent) than the 5D Mark II, 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 comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Canon 50D features an APS-C sensor and the Canon 5D Mark II a full frame sensor. The sensor area in the 5D Mark II is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 21MP, the 5D Mark II offers a higher resolution than the 50D (15.1MP), but the 5D Mark II nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.69μm for the 50D) 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 Canon 5D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark II for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Canon 50D are 23.8 x 15.8 inches or 60.4 x 40.2 cm for good quality, 19 x 12.7 inches or 48.3 x 32.2 cm for very good quality, and 15.8 x 10.6 inches or 40.2 x 26.8 cm for excellent quality prints.

The Canon EOS 50D has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-12800. The corresponding ISO settings for the Canon EOS 5D Mark II are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-25600.

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 5D Mark II offers substantially better image quality than the 50D (overall score 16 points higher). The advantage is based on 1.9 bits higher color depth, 0.5 EV in additional dynamic range, and 1.4 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 cannot only take still pictures, but also record videos. The 5D Mark II indeed provides for movie recording, while the 50D does not. The highest resolution format that the 5D Mark II can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 50D and the 5D Mark II are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the 5D Mark II offers a wider field of view (98%) than the one in the 50D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 5D Mark II has a higher magnification (0.71x vs 0.59x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 50D, the Canon 5D Mark II, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 50D has one, while the 5D Mark II does not. While the built-in flash of the 50D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 50D and the 5D Mark II write their files to Compact Flash cards.

Connectivity comparison

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 50D and Canon EOS 5D Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the 50D and the 5D Mark II have been discontinued, but can regularly be found used on ebay. The 50D was replaced by the Canon 60D, while the 5D Mark II was followed by the Canon 5D Mark III. Further information on the features and operation of the 50D and 5D Mark II can be found, respectively, in the Canon 50D Manual (free pdf) or the online Canon 5D Mark II Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 50D and the Canon 5D Mark II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 50D:

• Faster burst: Shoots at higher frequency (6.3 vs 3.9 flaps/sec) to capture the decisive moment.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).

Arguments in favor of the Canon EOS 5D Mark II:

• More detail: Has more megapixels (21 vs 15.1MP), which boosts linear resolution by 18%.
• Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
• Better low-light sensitivity: Can shoot in dim conditions (1.4 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.59x).

If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark II is the clear winner of the contest (7 : 3 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 50D and the Canon 5D Mark II place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 incomplete and does no justice, for example, to the way the 50D or the 5D Mark II perform in practice. 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 reviews

This is where reviews by experts come in. 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 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.
