Canon SL2 vs 70D
The Canon EOS Rebel SL2 (called Canon 200D in some regions) and the Canon EOS 70D are two digital cameras that were officially introduced, respectively, in June 2017 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The SL2 has a resolution of 24 megapixels, whereas the 70D provides 20 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 SL2 vs 70D
The side-by-side display below illustrates the physical size and weight of the Canon SL2 and the Canon 70D. 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 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 – the SL2 – represents 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 70D is notably larger (27 percent) than the Canon SL2. Moreover, the 70D is substantially heavier (67 percent) than the SL2. It is noteworthy in this context that the 70D 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 compare the optics available in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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 54 percent) than the 70D, 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 SL2 vs 70D
The size of the imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 70D is 2 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.
In terms of chip-set technology, the SL2 uses a more advanced image processing engine (DIGIC 7) than the 70D (DIGIC 5+), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the Canon SL2 offers a higher resolution of 24 megapixels, compared with 20 MP of the Canon 70D. 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 4.11μm for the 70D). However, it should be noted that the SL2 is much more recent (by 3 years and 11 months) than the 70D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The Canon EOS Rebel SL2 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Canon EOS 70D are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600..
For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the SL2 provides substantially higher image quality than the 70D, with an overall score that is 11 points higher. This advantage is based on 1.1 bits higher color depth, 1.8 EV in additional dynamic range, and 0.2 stops in additional 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SL2 provides a higher frame rate than the 70D. It can shoot video footage at 1080/60p, while the 70D is limited to 1080/30p.
Feature comparison: Canon SL2 vs 70D
Apart from body and sensor, cameras can and do differ across a range of features. The SL2 and the 70D 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 adjacent table lists some of the other core features of the Canon SL2 and Canon 70D along with similar information for a selection of comparators.

One feature that is present on the 70D, 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.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
Concerning the storage of imaging data, both the SL2 and the 70D write their files to SDXC cards.
Connectivity comparison: Canon SL2 vs 70D
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 Rebel SL2 and Canon EOS 70D 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 70D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 70D was succeeded by the Canon 80D.
Review summary: Canon SL2 vs 70D
So how do things add up? Is there a clear favorite between the Canon SL2 and the Canon 70D? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS Rebel SL2:
- More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
- Better image quality: Scores substantially higher (11 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1.8 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).
- More compact: Is smaller (122x93mm vs 139x104mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 302g or 40 percent) and hence easier to carry around.
- 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 (54 percent cheaper at launch).
- More modern: Reflects 3 years and 11 months of technical progress since the 70D launch.
Arguments in favor of the Canon EOS 70D:
- 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 (7 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (920 versus 650) 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 July 2013).
If the count of relative strengths (bullet points above) is taken as a measure, the SL2 is the clear winner of the match-up (12 : 6 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.
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 70D 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.

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
