Canon 600D versus Canon 100D

The Canon EOS 600D (called Canon T3i in some regions) and the Canon EOS 100D (labelled Canon SL1 in some countries) are two digital cameras that were officially introduced, respectively, in February 2011 and March 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 17.9 megapixel.

Body comparison

An illustration of the physical size and weight of the Canon 600D and the Canon 100D is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the 600D – represents the basis for the calculations 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 100D is notably smaller (20 percent) than the Canon 600D. Moreover, the 100D is markedly lighter (29 percent) than the 600D. In this context, it is worth noting that neither the 600D nor the 100D 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.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 100D was somewhat cheaper (by 8 percent) than the 600D at launch, but both cameras fall into the same price category. 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 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 and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 17.9 megapixel. This similarity in sensor specs implies that both the 600D and the 100D have the same pixel density, as well as the same pixel size. It should, however, be noted that the 100D is much more recent (by 2 years and 1 month) than the 600D, and its sensor will have benefitted from technological advances during this time.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 600D and the 100D 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 600D and Canon 100D along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the 600D and the 100D have been discontinued, but can regularly be found used on ebay. The 600D was replaced by the Canon 650D, while the 100D was followed by the Canon 200D.

Summary

So what is the bottom line? Is the Canon 600D better than the Canon 100D or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 600D:

  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Can take more shots (440 versus 380) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in February 2011).

Advantages of the Canon EOS 100D:

  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (4.9 vs 3.7 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (117x91mm vs 133x100mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 163g or 29 percent) and is thus easier to take along.
  • More modern: Reflects 2 years and 1 month of technical progress since the 600D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 100D emerges as the winner of the match-up (5 : 3 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 600D or the 100D. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
