Canon 1D Mark II vs SL3
The Canon EOS-1D Mark II and the Canon EOS Rebel SL3 (labelled Canon 250D in some countries) are two digital cameras that were officially introduced, respectively, in January 2004 and April 2019. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark II) and an APS-C (SL3) sensor. The 1D Mark II has a resolution of 8.2 megapixels, whereas the SL3 provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D Mark II and the Canon EOS Rebel SL3? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Canon 1D Mark II and the Canon SL3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
The SL3 can be obtained in two different colors (black, white), while the 1D Mark II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SL3 is considerably smaller (54 percent) than the Canon 1D Mark II. Moreover, the SL3 is substantially lighter (71 percent) than the 1D Mark II. It is worth mentioning in this context that the 1D Mark II is splash and dust resistant, while the SL3 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 1D Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (SL3). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1D Mark II gets 1200 shots out of its NP-E3 battery, while the SL3 can take 1070 images on a single charge of its LP-E17 power pack. As can be seen in the images above, the 1D Mark II has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the SL3, there are third party battery grips available as optional accessories (see here on eBay).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 SL3 was launched at a markedly lower price (by 87 percent) than the 1D 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1D Mark II features an APS-H sensor and the Canon SL3 an APS-C sensor. The sensor area in the SL3 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the SL3 uses a more advanced image processing engine (DIGIC 8) than the 1D Mark II (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SL3 offers a higher resolution of 24 megapixels, compared with 8.2 MP of the 1D Mark II. 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 8.17μm for the 1D Mark II). However, it should be noted that the SL3 is much more recent (by 15 years and 2 months) than the 1D Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon SL3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon 1D Mark II are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.
The SL3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS-1D Mark II has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Canon EOS Rebel SL3 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The SL3 indeed provides for movie recording, while the 1D Mark II does not. The highest resolution format that the SL3 can use is 4K/25p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 1D Mark II and the SL3 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 viewfinder in the 1D Mark II offers a wider field of view (100%) than the one in the SL3 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1D Mark II has a higher magnification (0.55x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1D Mark II and Canon SL3 along with similar information for a selection of comparators.

One feature that is present on the 1D Mark II, but is missing on the SL3 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 SL3 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 1D Mark II does not have a selfie-screen.
The Canon SL3 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 1D Mark II writes its imaging data to Compact Flash or SD cards, while the SL3 uses SDXC cards. The 1D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the SL3 only has one slot. The SL3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark II cannot take advantage of Ultra High Speed SD cards.
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-1D Mark II and Canon EOS Rebel SL3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1D Mark II does not provide wifi capability.
Studio photographers will appreciate that the Canon 1D Mark II (unlike the SL3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The SL3 is a recent model that features in the current product line-up of Canon. In contrast, the 1D Mark II has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D Mark II was succeeded by the Canon 1D Mark II N. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Which of the two cameras – the Canon 1D Mark II or the Canon SL3 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

- More modern: Reflects 15 years and 2 months of technical progress since the 1D Mark II launch.
If the count of relative strengths (bullet points above) is taken as a measure, the SL3 is the clear winner of the contest (19 : 11 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon 1D Mark II and the Canon SL3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D Mark II or the SL3. 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
