Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D Mark II N and the Canon EOS Rebel SL1? 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.

Body comparison: Canon 1D Mark II N vs SL1

An illustration of the physical size and weight of the Canon 1D Mark II N and the Canon SL1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The SL1 can be obtained in two different colors (black, white), while the 1D Mark II N 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 SL1 is considerably smaller (57 percent) than the Canon 1D Mark II N. Moreover, the SL1 is substantially lighter (74 percent) than the 1D Mark II N. It is worth mentioning in this context that the 1D Mark II N is splash and dust resistant, 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. A larger imaging sensor (as in the 1D Mark II N) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (SL1). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1D Mark II N gets 1200 shots out of its NP-E3 battery, while the SL1 can take 380 images on a single charge of its LP-E12 power pack. As can be seen in the images above, the 1D Mark II N 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 SL1, there are third party battery grips available as optional accessories (see here on eBay).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 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 86 percent) than the 1D Mark II N, 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 1D Mark II N vs SL1

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark II N features an APS-H sensor and the Canon SL1 an APS-C sensor. The sensor area in the SL1 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 SL1 uses a more advanced image processing engine (DIGIC 5) than the 1D Mark II N (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the SL1 offers a higher resolution of 17.9 megapixels, compared with 8.2 MP of the 1D Mark II N. 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 4.31μm versus 8.17μm for the 1D Mark II N). However, it should be noted that the SL1 is much more recent (by 7 years and 7 months) than the 1D Mark II N, 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 SL1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL1 for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Canon 1D Mark II N are 17.5 x 11.7 inch or 44.5 x 29.7 cm for good quality, 14 x 9.3 inch or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inch or 29.7 x 19.8 cm for excellent quality prints.

The SL1 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 N 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 SL1 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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The SL1 indeed provides for movie recording, while the 1D Mark II N does not. The highest resolution format that the SL1 can use is 1080/30p.

Feature comparison: Canon 1D Mark II N vs SL1

Apart from body and sensor, cameras can and do differ across a range of features. The 1D Mark II N and the SL1 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 N offers a wider field of view (100%) than the one in the SL1 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1D Mark II N 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 following table reports on some other key feature differences and similarities of the Canon 1D Mark II N, the Canon SL1, and comparable cameras.

One feature that is present on the 1D Mark II N, but is missing on the SL1 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 1D Mark II N writes its imaging data to Compact Flash or SD cards, while the SL1 uses SDXC cards. The 1D Mark II N features dual card slots, which can be very useful in case a memory card fails. In contrast, the SL1 only has one slot. The SL1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1D Mark II N cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison: Canon 1D Mark II N vs SL1

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 N and Canon EOS Rebel SL1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1D Mark II N (unlike the SL1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D Mark II N and the SL1 have been discontinued, but can regularly be found used on eBay. The 1D Mark II N was replaced by the Canon 1D Mark III, while the SL1 was followed by the Canon SL2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary: Canon 1D Mark II N vs SL1

So how do things add up? Is the Canon 1D Mark II N better than the Canon SL1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS-1D Mark II N:

If the number of relative strengths (bullet points above) is taken as a guide, the SL1 emerges as the winner of the match-up (14 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 N and the Canon SL1 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 1D Mark II N or the SL1 perform in practice. 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.

Expert reviews: Canon 1D Mark II N vs SL1

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
