Canon SL1 versus Canon 7D II

The Canon EOS Rebel SL1 (called Canon 100D in some regions) and the Canon EOS 7D Mark II are two digital cameras that were officially introduced, respectively, in March 2013 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The SL1 has a resolution of 17.9 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 SL1 vs Canon 7D II

An illustration of the physical size and weight of the Canon SL1 and the Canon 7D II 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 size 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 side – the SL1 – 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 (57 percent) than the Canon SL1. Moreover, the 7D Mark II is substantially heavier (124 percent) than the SL1. It is noteworthy in this context that the 7D Mark II is splash and dust-proof, while the SL1 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 SL1 gets 380 shots out of its LP-E12 battery, while the 7D Mark II can take 670 images on a single charge of its LP-E6N power pack.

The price is, of course, an important factor in any camera decision. 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 SL1 was launched at a markedly lower price (by 69 percent) than the 7D Mark II, 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 SL1 vs Canon 7D II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 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 SL1 and Canon 7D II sensor measures

With 20MP, the 7D Mark II offers a higher resolution than the SL1 (17.9MP), but the 7D Mark II has smaller individual pixels (pixel pitch of 4.10μm versus 4.31μm for the SL1). Yet, the 7D Mark II is a somewhat more recent model (by 1 year and 5 months) than the SL1, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

SL1 versus 7D Mark II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 Mark II has a markedly higher DXO score than the SL1 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.5 EV in additional dynamic range, and 0.4 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 7D Mark II provides a faster frame rate than the SL1. It can shoot movie footage at 1080/60p, while the SL1 is limited to 1080/30p.

 

Feature comparison: Canon SL1 vs Canon 7D II

Apart from body and sensor, cameras can and do differ across a range of features. The SL1 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 SL1 and Canon 7D II in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The SL1 has a touchscreen, while the 7D Mark II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The SL1 writes its imaging data to SDXC cards, while the 7D Mark II uses Compact Flash or SDXC cards. The 7D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the SL1 only has one slot.

The 7D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the SL1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the SL1 was succeeded by the Canon SL2.

Review summary: Canon SL1 vs Canon 7D II

So what conclusions can be drawn? Which of the two cameras – the Canon SL1 or the Canon 7D II – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon EOS Rebel SL1:

  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More compact: Is smaller (117x91mm vs 149x112mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 503g or 55 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in March 2013).


Advantages of the Canon EOS 7D Mark II:

  • More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • 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 (10 vs 4.9 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (670 versus 380) 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 (3.0 vs 2.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Was introduced somewhat (1 year and 5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the 7D Mark II is the clear winner of the contest (13 : 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.

SL1 05:13 7D Mark II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the SL1 or the 7D Mark II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
