Canon 300D versus Canon 70D

The Canon EOS 300D (called Canon Rebel in some regions) and the Canon EOS 70D are two digital cameras that were revealed to the public, respectively, in August 2003 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 300D has a resolution of 6.3 megapixel, whereas the 70D provides 20 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 300D vs Canon 70D

The side-by-side display below illustrates the physical size and weight of the Canon 300D and the Canon 70D. 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 300D – 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 70D is somewhat larger (3 percent) than the Canon 300D. Moreover, the 70D is markedly heavier (16 percent) than the 300D. It is noteworthy in this context that the 70D is splash and dust-proof, while the 300D does not feature any corresponding weather-sealing.

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 300D gets 400 shots out of its BP-511 battery, while the 70D can take 920 images on a single charge of its LP-E6 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The 300D was launched at a somewhat lower price (by 25 percent) than the 70D, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Canon 300D vs Canon 70D

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 70D is 1 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 70D uses a more advanced image processing engine (DIGIC 5+) than the 300D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Canon 300D and Canon 70D sensor measures

Despite having a slightly smaller sensor, the 70D offers a higher resolution of 20 megapixel, compared with 6.3 MP of the 300D. 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 4.11μm versus 7.38μm for the 300D). However, it should be noted that the 70D is much more recent (by 9 years and 10 months) than the 300D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

300D versus 70D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 70D offers substantially better image quality than the 300D (overall score 13 points higher). The advantage is based on 1.5 bits higher color depth, 0.8 EV in additional dynamic range, and 0.8 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. The 70D indeed provides for movie recording, while the 300D does not. The highest resolution format that the 70D can use is 1080/30p.

 

Feature comparison: Canon 300D vs Canon 70D

Apart from body and sensor, cameras can and do differ across a variety of features. The 300D and the 70D 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 300D, the Canon 70D, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 70D has a touchscreen, while the 300D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point or for making menu selections.

Both the 300D and the 70D have been discontinued, but can regularly be found used on eBay. The 300D was replaced by the Canon 350D, while the 70D was followed by the Canon 80D.

Review summary: Canon 300D vs Canon 70D

So what conclusions can be drawn? Which of the two cameras – the Canon 300D or the Canon 70D – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS 300D:

  • Less heavy: Is lighter (by 106g or 14 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in August 2003).


Arguments in favor of the Canon EOS 70D:

  • More detail: Has more megapixels (20 vs 6.3MP), which boosts linear resolution by 78%.
  • Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.8 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC).
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • 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: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 2.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (920 versus 400) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Reflects 9 years and 10 months of technical progress since the 300D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 70D is the clear winner of the contest (17 : 3 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

300D 03:17 70D

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 300D or the 70D. 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).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
