Canon 650D versus Canon 7D

The Canon EOS 650D (called Canon T4i in some regions) and the Canon EOS 7D are two digital cameras that were revealed to the public, respectively, in June 2012 and September 2009. 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. 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 650D vs Canon 7D

The physical size and weight of the Canon 650D and the Canon 7D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 – the 650D – represents the basis or 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 7D is notably larger (24 percent) than the Canon 650D. Moreover, the 7D is substantially heavier (50 percent) than the 650D. It is noteworthy in this context that the 7D is splash and dust-proof, while the 650D 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 650D gets 440 shots out of its LP-E8 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 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.

Any camera purchase will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 650D was launched at a markedly lower price (by 50 percent) than the 7D, 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.

Sensor comparison: Canon 650D vs Canon 7D

The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras 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.

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 650D and the 7D have the same pixel density, as well as the same pixel size. It should, however, be noted that the 650D is much more recent (by 2 years and 9 months) than the 7D, and its sensor will have benefitted from technological advances during this time.

The 650D has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 7D has a markedly higher DXO score than the 650D (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 are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison: Canon 650D vs Canon 7D

Beyond body and sensor, cameras can and do differ across a range of features. The 650D 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 table below summarizes some of the other core capabilities of the Canon 650D and Canon 7D in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 650D has a touchscreen, while the 7D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The 650D writes its imaging data to SDXC cards, while the 7D uses Compact Flash cards.

Both the 650D and the 7D have been discontinued, but can regularly be found used on eBay. The 7D was replaced by the Canon 7D Mark II, while the 650D was followed by the Canon 700D.

Review summary: Canon 650D vs Canon 7D

So how do things add up? Is there a clear favorite between the Canon 650D and the Canon 7D? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS 650D:

• Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k 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 148x111mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 285g or 33 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
• More modern: Reflects 2 years and 9 months of technical progress since the 7D launch.

Reasons to prefer the Canon EOS 7D:

• Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (800 versus 440) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• More heavily discounted: Has been around for much longer (launched in September 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the 650D comes out slightly ahead of the 7D (8 : 7 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 650D and the 7D in practical situations. 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 following table reports the overall rankings of the cameras as published by some of the major 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.
