Canon 600D vs S120

The Canon EOS 600D (called Canon T3i in some regions) and the Canon PowerShot S120 are two digital cameras that were announced, respectively, in February 2011 and August 2013. The 600D is a DSLR, while the S120 is a fixed lens compact. The cameras are based on an APS-C (600D) and a 1/1.7-inch (S120) sensor. The 600D has a resolution of 17.9 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 600D 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 side-by-side display below illustrates the physical size and weight of the Canon 600D and the Canon S120. 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 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 (56 percent) than the Canon 600D. In this context, it is worth noting that neither the 600D nor the S120 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the S120 has a lens built in, whereas the 600D 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 600D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 600D gets 440 shots out of its LP-E8 battery, while the S120 can take 230 images on a single charge of its NB-6LH power pack.

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.

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 600D, 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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth 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 depth-of-field 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 Canon 600D 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 600D has a native 3:2 aspect ratio, while the one in the S120 offers a 4:3 aspect.

With 17.9MP, the 600D offers a higher resolution than the S120 (12MP), but the 600D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.89μm for the S120) due to its larger sensor. However, the S120 is a much more recent model (by 2 years and 6 months) than the 600D, 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 600D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 600D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 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 600D has a native sensitivity range from ISO 100 to ISO 6400, 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 600D 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 600D has a notably higher overall DXO score than the S120 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.4 EV of lower dynamic range, and 1.7 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S120 provides a faster frame rate than the 600D. It can shoot movie footage at 1080/60p, while the 600D is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 600D 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 following table reports on some other key feature differences and similarities of the Canon 600D, the Canon S120, and comparable cameras.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The S120 has a touchscreen, while the 600D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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.

Concerning the storage of imaging data, both the 600D and the S120 write their files to SDXC cards. The S120 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 600D cannot take advantage of Ultra High Speed SD 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 600D 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 600D has a hotshoe, while the S120 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the 600D and the S120 have been discontinued, but can regularly be found used on ebay. The 600D was replaced by the Canon 650D, while the S120 does not have a direct successor. Further information on the features and operation of the 600D and S120 can be found, respectively, in the Canon 600D Manual (free pdf) or the online Canon S120 Manual.

Review summary

So how do things add up? Is the Canon 600D better than the Canon S120 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS 600D:

• More detail: Offers more megapixels (17.9 vs 12MP) with a 25% higher linear resolution.
• Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (1.7 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (440 versus 230) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in February 2011).

Arguments in favor of the Canon PowerShot S120:

• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (12.1 vs 3.7 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 600D requires a separate lens.
• More compact: Is smaller (100x59mm vs 133x100mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 600D).
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 2 years and 6 months of technical progress since the 600D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 600D comes out slightly ahead of the S120 (13 : 12 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

How about other alternatives? Do the specifications of the Canon 600D 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 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 600D or the S120 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 why hands-on reviews by experts are important. 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
