Canon 300D vs 7D

The Canon EOS 300D (called Canon Rebel in some regions) and the Canon EOS 7D are two digital cameras that were announced, respectively, in August 2003 and September 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 300D has a resolution of 6.3 megapixels, whereas the 7D provides 17.9 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 300D vs 7D

An illustration of the physical size and weight of the Canon 300D and the Canon 7D 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 measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 7D is notably larger (17 percent) than the Canon 300D. Moreover, the 7D is markedly heavier (33 percent) than the 300D. It is noteworthy in this context that the 7D 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 compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 300D gets 400 shots out of its BP-511 battery, while the 7D can take 800 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 would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 300D was launched at a markedly lower price (by 47 percent) than the 7D, which puts it into a different market segment. 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 7D

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 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 7D is 3 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 300D and Canon 7D sensor measures

Despite having a slightly smaller sensor, the 7D offers a higher resolution of 17.9 megapixels, compared with 6.3 MP of the 300D. This megapixels 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 7.38μm for the 300D). However, it should be noted that the 7D is much more recent (by 6 years) than the 300D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The Canon EOS 300D has a native sensitivity range from ISO 100 to ISO 1600 The corresponding ISO settings for the Canon EOS 7D are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800..

300D versus 7D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the 7D offers substantially better image quality than the 300D (overall score 11 points higher). The advantage is based on 1 bits higher color depth, 0.9 EV in additional dynamic range, and 0.7 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 7D indeed provides for movie recording, while the 300D does not. The highest resolution format that the 7D can use is 1080/30p.

 

Feature comparison: Canon 300D vs 7D

Beyond body and sensor, cameras can and do differ across a range of features. The 300D and the 7D 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 7D, and comparable cameras.

One feature that is present on the 7D, but is missing on the 300D 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.

Concerning the storage of imaging data, both the 300D and the 7D write their files to Compact Flash cards.

Studio photographers will appreciate that the Canon 7D (unlike the 300D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 300D and the 7D have been discontinued, but can regularly be found used on eBay. The 300D was replaced by the Canon 350D, while the 7D was followed by the Canon 7D Mark II.


Review summary: Canon 300D vs 7D

So what conclusions can be drawn? Is there a clear favorite between the Canon 300D and the Canon 7D? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon EOS 300D:

  • More compact: Is smaller (142x99mm vs 148x111mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 211g or 25 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in August 2003).


Arguments in favor of the Canon EOS 7D:

  • More detail: Has more megapixels (17.9 vs 6.3MP), which boosts linear resolution by 69%.
  • Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • 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 (920k vs 118k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (8 vs 2.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (800 versus 400) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More modern: Reflects 6 years of technical progress since the 300D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 7D is the clear winner of the contest (15 : 4 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 04:15 7D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 300D or the 7D handle or perform in practice. 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
