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 revealed to the public, 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

The side-by-side display below illustrates the physical size and weight of the Canon 30D and the Canon SL1. 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 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 camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 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 dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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.

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.

30D versus SL1 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 cannot only take still pictures, but also record videos. 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

Beyond 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 following table reports on some other key feature differences and similarities of the Canon 30D, the Canon SL1, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the 30D and the SL1 have been discontinued, but can regularly be found used on eBay. The 30D was replaced by the Canon 40D, while the SL1 was followed by the Canon SL2.

Review summary: Canon 30D vs Canon SL1

So how do things add up? Is there a clear favorite between the Canon 30D and the Canon SL1? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 30D:

  • Easier setting verification: Has 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).


Reasons to prefer 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.
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • 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 (10 : 4 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.

30D 04:10 SL1

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 30D and the SL1 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. This is where reviews by experts come in. 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 refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
