Canon 1D Mark IV vs SL3
The Canon EOS-1D Mark IV and the Canon EOS Rebel SL3 (labelled Canon 250D in some countries) are two digital cameras that were officially introduced, respectively, in October 2009 and April 2019. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark IV) and an APS-C (SL3) sensor. The 1D Mark IV has a resolution of 16 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 IV 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 side-by-side display below illustrates the physical size and weight of the Canon 1D Mark IV and the Canon SL3. 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 measures are rounded to the nearest millimeter.
The SL3 can be obtained in two different colors (black, white), while the 1D Mark IV 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 IV. Moreover, the SL3 is substantially lighter (63 percent) than the 1D Mark IV. It is worth mentioning in this context that the 1D Mark IV 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 IV) 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 IV gets 1500 shots out of its LP-E4 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 IV 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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 SL3 was launched at a markedly lower price (by 88 percent) than the 1D Mark IV, 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 sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Canon SL3 an APS-C sensor. The sensor area in the SL3 is 36 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 IV (DIGIC IV), 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 16 MP of the 1D Mark IV. 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 5.70μm for the 1D Mark IV). However, it should be noted that the SL3 is much more recent (by 9 years and 5 months) than the 1D Mark IV, 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 IV are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 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 IV has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. 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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 SL3 provides a better video resolution than the 1D Mark IV. It can shoot movie footage at 4K/25p, while the 1D Mark IV is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The 1D Mark IV 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 IV 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 IV has a higher magnification (0.58x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 1D Mark IV, the Canon SL3, and comparable cameras.

One feature that is present on the 1D Mark IV, 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 IV 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 IV writes its imaging data to Compact Flash or SDHC cards, while the SL3 uses SDXC cards. The 1D Mark IV 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 IV 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 IV 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 IV does not provide wifi capability.
Studio photographers will appreciate that the Canon 1D Mark IV (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 IV has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the 1D Mark IV from Canon. 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 conclusions can be drawn? Is there a clear favorite between the Canon 1D Mark IV and the Canon SL3? Which camera is better? The listing below highlights the relative strengths of the two models.

If the count of relative strengths (bullet points above) is taken as a measure, the SL3 is the clear winner of the contest (17 : 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 IV 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 says little about, for example, the shooting experience and imaging performance of the 1D Mark IV and the SL3 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
