Canon SL2 versus Canon 7D II

The Canon EOS Rebel SL2 (called Canon 200D in some regions) and the Canon EOS 7D Mark II are two digital cameras that were officially introduced, respectively, in June 2017 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The SL2 has a resolution of 24 megapixel, whereas the 7D Mark II 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 SL2 vs Canon 7D II

The side-by-side display below illustrates the physical size and weight of the Canon SL2 and the Canon 7D II. 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. 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 SL2 – 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 7D II is considerably larger (47 percent) than the Canon SL2. Moreover, the 7D Mark II is substantially heavier (101 percent) than the SL2. It is noteworthy in this context that the 7D Mark II is splash and dust-proof, while the SL2 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 SL2 gets 650 shots out of its LP-E17 battery, while the 7D Mark II can take 670 images on a single charge of its LP-E6N 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 SL2 was launched at a markedly lower price (by 69 percent) than the 7D Mark II, 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 SL2 vs Canon 7D II

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. 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 7D Mark II is 1 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.

Canon SL2 and Canon 7D II sensor measures

Despite having a slightly smaller sensor, the Canon SL2 offers a higher resolution of 24 megapixel, compared with 20 MP of the Canon 7D II. 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 3.72μm versus 4.10μm for the 7D Mark II). However, it should be noted that the SL2 is much more recent (by 2 years and 9 months) than the 7D Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

SL2 versus 7D Mark II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the SL2 has a notably higher overall DXO score than the 7D Mark II (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.2 bits higher color depth, 1.6 EV in additional dynamic range, 0.1 stops of reduced low light sensitivity. 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 (1080/60p).

 

Feature comparison: Canon SL2 vs Canon 7D II

Apart from body and sensor, cameras can and do differ across a range of features. The SL2 and the 7D Mark II 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 SL2 and Canon 7D II in connection with corresponding information for a sample of similar cameras.

Review summary: Canon SL2 vs Canon 7D II

So how do things add up? Is the Canon SL2 better than the Canon 7D II or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon EOS Rebel SL2:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.6 EV of extra DR).
  • 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 (122x93mm vs 149x112mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 457g or 50 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
  • More modern: Reflects 2 years and 9 months of technical progress since the 7D Mark II launch.


Advantages of the Canon EOS 7D Mark II:

  • 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.
  • Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
  • 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 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the SL2 is the clear winner of the match-up (10 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

SL2 10:05 7D Mark II

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 SL2 and the 7D Mark II 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
