Canon 30D versus Canon SL1

The Canon EOS 30D and the Canon EOS Rebel SL1 (labelled Canon 100D in some countries) are two digital cameras that were announced, respectively, in February 2006 and March 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 30D has a resolution of 8.2 megapixel, whereas the SL1 provides 17.9 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 30D vs Canon SL1

An illustration of the physical size and weight of the Canon 30D and the Canon SL1 is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 30D – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SL1 is considerably smaller (30 percent) than the Canon 30D. Moreover, the SL1 is substantially lighter (48 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the SL1 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 30D gets 750 shots out of its BP-511A battery, while the SL1 can take 380 images on a single charge of its LP-E12 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera purchase 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 SL1 was launched at a markedly lower price (by 61 percent) than the 30D, 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: Canon 30D vs Canon SL1

The 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 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 more expensive and 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 SL1 is 2 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the SL1 uses a more advanced image processing engine (DIGIC 5) than the 30D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.

Canon 30D and Canon SL1 sensor measures

Despite having a slightly smaller sensor, the SL1 offers a higher resolution of 17.9 megapixel, compared with 8.2 MP of the 30D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 6.42μm for the 30D). However, it should be noted that the SL1 is much more recent (by 7 years) than the 30D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The SL1 has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

30D versus SL1 MP

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 SL1 has a markedly higher DXO score than the 30D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 0.5 EV in additional dynamic range, and 0.2 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 can also record movies. The SL1 indeed provides for movie recording, while the 30D does not. The highest resolution format that the SL1 can use is 1080/30p.

 

Feature comparison: Canon 30D vs Canon SL1

Apart from body and sensor, cameras can and do differ across a range of features. The 30D and the SL1 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 adjacent table lists some of the other core features of the Canon 30D and Canon SL1 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

One feature that is present on the 30D, but is missing on the SL1 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 30D writes its imaging data to Compact Flash cards, while the SL1 uses SDXC cards.

Review summary: Canon 30D vs Canon SL1

So how do things add up? Which of the two cameras – the Canon 30D or the Canon SL1 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS 30D:

  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Can take more shots (750 versus 380) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in February 2006).


Arguments in favor of the Canon EOS Rebel SL1:

  • More detail: Has more megapixels (17.9 vs 8.2MP), which boosts linear resolution by 48%.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 2).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (117x91mm vs 144x106mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 378g or 48 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (61 percent cheaper at launch).
  • More modern: Reflects 7 years of technical progress since the 30D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the SL1 is the clear winner of the contest (12 : 4 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.

30D 04:12 SL1

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 30D or the SL1 handle or 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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 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.
