Canon T5i versus Canon 20D

The Canon EOS Rebel T5i (called Canon 700D in some regions) and the Canon EOS 20D are two digital cameras that were officially introduced, respectively, in March 2013 and August 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The T5i has a resolution of 17.9 megapixel, whereas the 20D provides 8.2 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 T5i vs Canon 20D

The side-by-side display below illustrates the physical size and weight of the Canon T5i and the Canon 20D. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 side – the T5i – 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 20D is notably larger (15 percent) than the Canon T5i. Moreover, the 20D is markedly heavier (33 percent) than the T5i. In this context, it is worth noting that neither the T5i nor the 20D 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 T5i gets 440 shots out of its LP-E8 battery, while the 20D can take 700 images on a single charge of its BP-511A power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T5i was launched at a markedly lower price (by 57 percent) than the 20D, 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 T5i vs Canon 20D

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. 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 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 20D is 2 percent bigger. 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.

Sensor size

Despite having a slightly smaller sensor, the Canon T5i offers a higher resolution of 17.9 megapixel, compared with 8.2 MP of the Canon 20D. 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 20D). However, it should be noted that the T5i is much more recent (by 8 years and 7 months) than the 20D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

For most 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The T5i indeed provides movie recording capabilities, while the 20D does not. The highest resolution format that the T5i can use is 1080/30p.

Feature comparison: Canon T5i vs Canon 20D

Apart from body and sensor, cameras can and do differ across a variety of features. The T5i and the 20D 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 T5i and Canon 20D along with similar information for a selection of comparators.

Review summary: Canon T5i vs Canon 20D

So what conclusions can be drawn? Is there a clear favorite between the Canon T5i and the Canon 20D? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS Rebel T5i:

  • More detail: Offers more megapixels (17.9 vs 8.2MP) with a 48% higher linear resolution.
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 118k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More compact: Is smaller (133x100mm vs 144x106mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 190g or 25 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
  • More modern: Reflects 8 years and 7 months of technical progress since the 20D launch.

Arguments in favor of the Canon EOS 20D:

  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Gets more shots (700 versus 440) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in August 2004).

If the number of relative strengths (bullet points above) is taken as a guide, the T5i is the clear winner of the match-up (10 : 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.

T5i 10:04 20D

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 T5i or the 20D. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
