Canon 6D vs SL2
The Canon EOS 6D and the Canon EOS Rebel SL2 (labelled Canon 200D in some countries) are two digital cameras that were revealed to the public, respectively, in September 2012 and June 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (6D) and an APS-C (SL2) sensor. The 6D has a resolution of 20 megapixels, whereas the SL2 provides 24 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 6D vs SL2
An illustration of the physical size and weight of the Canon 6D and the Canon SL2 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. 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 side – the 6D – 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 SL2 is notably smaller (30 percent) than the Canon 6D. Moreover, the SL2 is substantially lighter (41 percent) than the 6D. It is worth mentioning in this context that the 6D is splash and dust resistant, 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. A larger imaging sensor (as in the 6D) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (SL2). You can compare the optics available in the Canon EF Lens Catalog.
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 decision will obviously take relative prices into account. 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 SL2 was launched at a markedly lower price (by 74 percent) than the 6D, 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 6D vs SL2
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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 6D features a full frame sensor and the Canon SL2 an APS-C sensor. The sensor area in the SL2 is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the SL2 uses a more advanced image processing engine (DIGIC 7) than the 6D (DIGIC 5+), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SL2 offers a higher resolution of 24 megapixels, compared with 20 MP of the 6D. 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 3.72μm versus 6.57μm for the 6D). However, it should be noted that the SL2 is much more recent (by 4 years and 9 months) than the 6D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The SL2 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS 6D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS Rebel SL2 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200..
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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 have a sensor with sufficiently fast read-out times for moving pictures, but the SL2 provides a faster frame rate than the 6D. It can shoot movie footage at 1080/60p, while the 6D is limited to 1080/30p.
Feature comparison: Canon 6D vs SL2
Apart from body and sensor, cameras can and do differ across a range of features. The 6D and the SL2 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 6D and Canon SL2 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 6D, but is missing on the SL2 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.The SL2 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 6D does not have a selfie-screen.
Concerning the storage of imaging data, both the 6D and the SL2 write their files to SDXC cards.
Connectivity comparison: Canon 6D vs SL2
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 6D and Canon EOS Rebel SL2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The SL2 is a recent model that features in the current product line-up of Canon. In contrast, the 6D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 6D was succeeded by the Canon 6D Mark II.
Review summary: Canon 6D vs SL2
So how do things add up? Is there a clear favorite between the Canon 6D and the Canon SL2? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS 6D:
- Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Longer lasting: Can take more shots (1090 versus 650) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More heavily discounted: Has been available for much longer (launched in September 2012).
Advantages of the Canon EOS Rebel SL2:
- More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
- More dynamic range: Captures a broader range of light and dark details (1.3 EV of extra DR).
- Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 5+).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
- 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.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (122x93mm vs 145x111mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 317g or 41 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (74 percent cheaper at launch).
- More modern: Reflects 4 years and 9 months of technical progress since the 6D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the SL2 is the clear winner of the contest (15 : 5 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 specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 6D or the SL2. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Care should be taken when interpreting the review scores above, 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 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.
