Canon 50D vs S120

The Canon EOS 50D and the Canon PowerShot S120 are two digital cameras that were revealed to the public, respectively, in August 2008 and August 2013. The 50D is a DSLR, while the S120 is a fixed lens compact. The cameras are based on an APS-C (50D) and a 1/1.7-inch (S120) sensor. The 50D has a resolution of 15.1 megapixels, whereas the S120 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 50D and the Canon PowerShot S120? 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

The physical size and weight of the Canon 50D and the Canon S120 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon S120 is considerably smaller (63 percent) than the Canon 50D. It is worth mentioning in this context that the 50D is splash and dust resistant, while the S120 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the S120 has a lens built in, whereas the 50D 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 50D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 50D gets 800 shots out of its Canon BP-511A battery, while the S120 can take 230 images on a single charge of its Canon NB-6LH power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. 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 S120 was launched at a lower price than the 50D, despite having a lens built in. 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.

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 50D features an APS-C sensor and the Canon S120 a 1/1.7-inch sensor. The sensor area in the S120 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 50D has a native 3:2 aspect ratio, while the one in the S120 offers a 4:3 aspect.

With 15.1MP, the 50D offers a higher resolution than the S120 (12MP), but the 50D nevertheless has larger individual pixels (pixel pitch of 4.69μm versus 1.89μm for the S120) due to its larger sensor. However, the S120 is a much more recent model (by 4 years and 11 months) than the 50D, 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 50D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 50D for good quality output (200 dots per inch) amounts to 23.8 x 15.8 inches or 60.4 x 40.2 cm, for very good quality (250 dpi) 19 x 12.7 inches or 48.3 x 32.2 cm, and for excellent quality (300 dpi) 15.8 x 10.6 inches or 40.2 x 26.8 cm. The corresponding values for the Canon S120 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 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 PowerShot S120 are ISO 80 to ISO 12800 (no boost).

In terms of underlying technology, the 50D is build around a CMOS sensor, while the S120 uses a BSI-CMOS imager. 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 50D has a notably higher overall DXO score than the S120 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 0.5 EV of lower dynamic range, and 1.5 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 S120 indeed provides for movie recording, while the 50D does not. The highest resolution format that the S120 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 50D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the S120 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 50D and Canon S120 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 50D, but is missing on the S120 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 Canon S120 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 50D writes its imaging data to Compact Flash cards, while the S120 uses SDXC 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 PowerShot S120 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 50D has a hotshoe, while the S120 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Canon 50D (unlike the S120) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 50D and the S120 have been discontinued, but can regularly be found used on ebay. The 50D was replaced by the Canon 60D, while the S120 does not have a direct successor. Further information on the features and operation of the 50D and S120 can be found, respectively, in the Canon 50D Manual (free pdf) or the online Canon S120 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon 50D and the Canon S120? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS 50D:

• More detail: Offers more megapixels (15.1 vs 12MP) with a 14% higher linear resolution.
• Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (1.5 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (800 versus 230) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in August 2008).

Reasons to prefer the Canon PowerShot S120:

• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (12.1 vs 6.3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the 50D requires a separate lens.
• More compact: Is smaller (100x59mm vs 146x108mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 50D).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 4 years and 11 months of technical progress since the 50D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 50D comes out slightly ahead of the S120 (12 : 11 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.

How about other alternatives? Do the specifications of the Canon 50D and the Canon S120 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 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 50D and the S120 in practical situations. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
